Hey mate! It certainly makes a LOT of data!! at least when using a 'region of interest' crop of the camera sensor, file sizes can be kept down somewhat, but inevitably it still ends up being a chunk! :-D I wish i'd had a big scope for this experiment like my old 250 or 300mm newtonians, I think they'd have done real justice to it, still the Esprit didn't disappoint even running at 645mm focal length! :-) Thanks for watching!

The guiding and imaging from the same chip is a super interesting idea, I know SBIG and similar had some cameras a while ago that had a built-in separate guide sensor next to the main imaging sensor but the only issue was it would be looking through any filters etc, making guiding while imaging in narrowband for example quite difficult, I'd love if the idea was revisited though!

Hey mate, hope you are well! - without a doubt the shorter an exposure the better from a sharpness standpoint, but at the end of the day you still need enough exposure to make the image even worth stacking, so there's always going to be a balance until we have cameras capable of 0e read noise! :-) 'lucky imaging' is a very wooly term which leaves itself open to personal interpretation of what you'd define as lucky! I've personally seen exposures as long as 5s display significant shot to shot variance in sharpness, indicating that they could still be sorted and stacked delivering sharper results than traditional approaches, I'd call that lucky imaging still personally, but I appreciate it won't fit everyone's definition 👍 I can't wait for newer cameras to hit the market in the coming decade perhaps which will allow us to go shorter than ever with our deepsky exposures, good times are ahead! :-D Thank you for watching and sharing some discussion!

Beautiful result. Thanks for the great video that clearly explained the concept of lucking imaging deep sky object. I'd love to give it a go, my QHY294MM has fairly low read noise and very small pixels so seems well suited for it. I found out that with SharpCap I can capture a ROI in the centre and thus not have to deal with thousands of 47mp fits. Would have loved to see a side-by-side with traditional long-exposes stacked. My suspicion is with smaller apertures you might be diffraction limited so there's less to gain with lucky imaging.

I'm sure that was a lot of work but we'll worth it given the quality. I learned a whole lot here about read noise and the concept itself was really well explained. First time I've come across it (although I've been in the game a whole 9 months lol). Really appreciate the shoutout mate and just love seeing how you used it within the video. Such a kick to hear it in someone else's video. No doubt for me you're one of the top astrophotography channels out there.

A huge part of the seeing equation is local. The telescope, and the immediate site. As a matter of fact seeing is mostly local, not the far atmosphere. Never the less lucky will work there too. If you null out the local seeing you would get many more diffraction limited frames.

@@lukomatico Hi Luke. The 462 MC and 533MC behave similarly in short exposures of 0.5 to 1.0s for Deep Sky. The advantage of the 533MC is the cooling that significantly reduces the noise of the individual frames. As soon as I test with my SC 10 "f/6.3 I will tell you (f/6.3 is the native focal radius of some Meade SC from the 90s). I usually use it at f/4 with FR. With the small field of the 533MC I can avoid the coma and spherical aberrations that the FR produces at the edge of the field due to the short f/4 focal ratio foa an SC. Regards

Lucky imaging is not about freeze framing the seeing. Seeing is not constant. Lucking imaging is about capturing when the momentary seeing is better than the average and stacking those images. And it was amateurs that developed lucking imaging. It doesn't work on large telescopes.

Hey there! Thanks for your comment :-) I believe we mostly agree on this, but perhaps would personally phrase a discription differently even though the essence of what's being described is the same. Lucky imaging really IS about freeze framing the seeing, simply because the seeing isn't constant as you say - you take the best and stack them, rejecting the worst. It does indeed work on large telescopes though, better than on small telescopes even as they have a higher overall resolution limit - why else would the best terrestrially captured planetary images come from huge scopes using planetary lucky imaging techniques, and not from small scopes 👍

In planet imaging, key point is how many images will be rejected below some quality point. Sometimes it could be 95%, and almost always more than 80%. How many images survived from those 2500? I have started (April 2022) astrophotography from EAA. Then, I started (July 2022) to keep individual EAA frames, and analyze them. Only -10-20% of images were true lucky (below expected threshold). Exposure were 5-10 sec (actually correct ones calculated by Sharpcap) So, 360 frames per hour, 36 survive. I could say, 7000-10000 such frames are needed and only 700-1000 will be selected for WBPP. This will be true lucky imaging. I learned about Pixinsight and NINA in October 2022, these approaches never overlapped, but I will return to lucky imaging that I have used with EAA.

@derekbaker3279
3 жыл бұрын
Wonderful video Luke (as always!). 👍👍 Four points of follow-up... 1. A question: Did you use all of the short sub-exposures to make the final image? The reason I ask is as follows: During long exposures, the atmosphere is constantly changing, meaning that there are moments when the image is steady, and moments when some or all of the image has been distorted by the atmospheric turbulence. Because both occur quite frequently, then both good & bad moments of seeing will contribute to what the camera records during a long exposure. In a sense, the final result of a long exposure is sort of an average of what the camera 'sees' during the 'sharp moments' and 'blurred moments'. Now, if you take many short exposures, I would think that you will have captured some that occurred only during 'sharp moments', and some that captured the object only during 'blurred moments'. If you then combine all of the sub-exposures, wouldn't you be getting the same average of the 'sharp moments' & 'blurred moments' as a long exposure? I would think that the real benefit of taking huge numbers of short sub-exposures would come from tossing the images that were blurred & only stacking the images taken during the 'sharp moments' (i.e only choose shots which would have the smallest stars in the image). Having said all that, the fact is that your final image of M57 is quite impressive. Perhaps my logic is incorrect? 2. I should point out that the benefit of 'lucky imaging' is greater as the aperture of the telescope increases, because larger apertures look through larger chunks of the atmosphere, which increases the likelyhood that some part of that chunk of atmosphere is turbulent & distorting the image. Anyone who has done planetary or double-star observing (visually) with a larger aperture telescope knows that moments when the object is truly sharp & undistorted are much less frequent with larger scopes (although those moment will show huge amounts of detail). 3. It's interesting to note that, in the past, that the following question was posed & answered (*): "What size of refractor delivers the optimum price/performance ratio for visual observing?". Yes, larger apertures of refractor provide more theoretical resolution and high contrast, but smaller apertures have fewer moments of bad seeing & have the same high contrast. Well, it turns out that, for typical observing conditions that most amateurs experience (especially at middle lattitudes), the 'sweet spot' for refractors is....yup!....a 5-inch aperture! (*) It may have been Robert Burnham Jr., a noted 20th visual astronomy expert & author of the much-loved three-volume "Burnham's Celestial Handbook". 4. For several decades, astrophotographers wishing to battle the effects of seeing during long exposures have made use of an "Adaptive Optics" unit, which is placed in front of the filters & camera. They can be quite effective when objects are too faint for short exposures & the imaging is done with larger apertures. Here's a link to a company that has been making Adaptive Optics for astrophotographers for quite a while. diffractionlimited.com/product/ao-8a/

Hey Derek! Thank you so much for taking the time to write such an in depth comment! :-) RE: 1 - I did not use all of the exposures, I used around 65-70% IIRC which was still too many, but I needed some signal! :D It's not too bad to stack slightly poorer frames with better ones when you are using advanced stacking algorithms which are able to weight the subframes and give greater presence to those that are sharper and a diminished effect to those that are lower quality, it takes out some of the need to 'weed out' the bad subs, just as long as you've gotten rid of the very worst the software can make a good guess as to which subs it should stack based on FWHM etc :-) If you were purely averaging when stacking then absolutely you'd want to get rid of everything that wasn't the cream of the crop though! RE: 2 -You're absolute right mate! I've had first hand experience with that kind of effect for sure, as you say it's way more pronounced on a larger aperture - my 12" newtonian showed it strongly when I was lucky imaging the core of the cat's eye nebula a few years ago with it - some frames were crystalline, others were... well,... not so good!! :D RE: 3 -I wish I'd actually taken a look through my Esprit 120 visually, but so far I haven't! I really should rectify that soon. - I always liked visual through newts when I had them, but rather surprisingly my best ever visual view of the ring nebula came from an 80mm apo, it was just there as plain as day, I couldn't quite believe what I was seeing from such a small scope! amazing stuff :-) RE: 4 -Oh man, I'd love an AO someday if it became feasible to own one, they are incredible aren't they? :-) If I won the lottery I'd have one of the laser artificial star ones, but I'd have to move house as I live near a flightpath and I don't think they'd approve haha :-) A man can dream!

I thought these might peak your interest :D I did initially think the ASI482 would have the lower read noise with it's massive 5.8um pixels, However, I do notice the read noise is lower on the 485 which I didn't expect considering it has much smaller 2.9um pixels. I'm of course getting one, that goes without saying, and might opt for the 485 version as it gives 0.6"/pixels with the 200p which sounds perfect for Lucky imaging, and 4x the real estate compared to my 462 for framing those lovely galaxies.

However, for some reason, the settings in the capture software reverted to "PNG" format, which I couldn't debayer using Siril. The solution I found was as follows: convert PNG to FITS format files using a Linux tool: mogrify -format fits -path ../converted/ *.png. Then in Siril, change the settings to use a predetermined debayer setting (because no debayer info is included in the converted file), and then debayer with Siril. This solved my issue, this method does also work for "tif" files.

Thanks for putting this out there, this is an interesting field and I found this searching for lucky imaging. It would have been really useful to show your great final image against an image taken using the same gear by the more traditional method with 3 or 5 minute subs etc Quick question - I thought one of the principles of lucky imaging was discarding those shots that may not be as clear due to atmospheric impact at that specific time, ensuring you are only stacking the sharpest ones possible. It looks as though you may not have done this, was there a particular reason why?

Hey there! - thank you so much for watching and giving such a detailed comment! :-) Regarding frame rejection : you're absolutely right that you'd usually be very discriminatory with frame selection when performing lucky imaging, however some benefit to resolution can be realised just by using short subs vs the usual long ones, even if you stack nearly all of them without much rejection - I've tested this myself an there's definitely an increase in detail, though not as extreme as only stacking the absolute best few frames 👍 The reason I kept more frames was down to needing the extra SNR that more exposure brings, the end result was still quite noisy so a 'best 10%' stack would have been too noisy to use for the video :-) You made a good suggestion about showing a version taken with longer exposures would have been good, I'd definitely try and do that next time - I just need more clear nights to do it all haha! Thanks again for watching 🙏

With Lucky Imaging, are you suppose to just chose the best lights rather than stack many?

Hey Ian! You'd usually stack just the best ones, but in an ideal world you'd have lots of good frames to stack rather than just a few! :-D I stacked the best 65%-ish of those lights that I captured for reference :-) Clear skies!

Now that’s a thought provoker. Excellent image. How were the star shapes, I’ve seen some of these images with slightly oblong stars.

Hey mate! - The star shapes were lovely and round, no problems there :-) I wonder if some of the images you've seen in the past were from alt-az mounted scopes as this method is popular among users of them? field rotation over time gives you a similar effect to the egged stars :-) Thank you so much for watching mate!

I didn't get if you talked about what may be the most important part of lucky imaging. How to find the "lucky" frames when you have thousands and thousands of total images. Did you just throw everything in Pipp? How did you measure which frames to keep. That would be the whole point of this exercise, to throw away all but the sharpest ones.

Hey cucu! - You are right , I should have elaborated more on my selection!! - I took around 2100 frames but did not use them all, I told DSS to stack the best 70% I think it was, I'd have loved to be more careful in selection but I just couldn't find the energy to go through all the subs manually to check them at that time :D Definitely something I should have brought up and talked more about though, cheers! I hope you have a great weekend mate!

@@lukomatico Thanks! No worries, it was a very cool exercise indeed. Ever since Astrobiscuit's video came out, I've been wondering about this. At some point I will end up trying it. On the other hand, for true lucky imaging we'd need much shorter exposures to essentially mitigate seeing wobbles. Probably even 1 second is on the upper limit... which brings up the need for much larger aperture for light gathering capabilities. Also, likely you will need to ditch way more frames. Take the example of planetary luck imaging, they take 10-20k frames and keep only 10% in average...

Nice video. Trying a new style? Seems a little Trevor Jones but with actual content and not just wistfully looking up while talking and then showing a photo. One thing I would suggest is to try siril again now you have the individual tiff files but use the generalized extreme stacking method and select weighted on the stacking page. Should work well on such a large data set.

Hey Michael! You got me :D I was trying a bit of a different style, - I'd like to make more videos like this in the future, as I feel really quite proud of it :-) I was forcing myself to get 'something' out each week and my creativity and quality suffered as a result I think. RE: Siril, I'll keep the .tiffs and give that a go! Thank you for the suggestion :-) I was just so relieved to find that something had finally worked that I just went with it and stacked everything in DSS! This is something I'd like to revisit as I'm really interested in the subject, It'd be interesting with a colour camera as originally planned and maybe a "proper" scope for it, 10/12" newt etc - Then it's just a case of finally getting some better than average seeing! Thank you so much for watching mate, I hope you have a great weekend!
