I’m, glad the presentation helped. Despite some tradeoffs with shooting with your Dob, it can be a lot of fun, not too hard, and a big scope can be very productive on smaller to medium sized targets.

@@stevenmiller5452 I love how I can incorporate it into my visual observing. Also, I feel much more connected to the images from my Dob compared to my widefield setup, because of all the years I spent looking at those same objects. Now I just wish I had better tracking ;)

Congratulations on your 10th anniversary. I have been watching & subscribed for about 9 years. It’s helped me so much but I have to confess I find I am watching less videos. Mainly because of life changes which gives me very little time for any AP. Hoping this will be reversed later this year. Enjoyed all of the presenters over the years. I do miss Adam and the background kitchen! Keep up the great work 🎉

Holy wowzers! just look at the resolution on that system. Well done to these 2 Legends! I was just reading about proto planetary disks in Orion's trapezium, I didnt think this kind of resolution was possible with ground based telescopes. AND THAT WITH A TELESCOPE FROM THE 60's wowww!

Hello Kai, great & inspiring presentation ! Just one technical question: You are using a (Thorlabs ?) grating with 300 lines / mm. Is this due to the fact that spectra from gratings with higher resolution will not fit onto the relatively small S50 chip ?

When you observe in the summer you dress like it is autumn. When you observe in the autumn you dress like it is winter. When you observe in the winter you put on an extension tube to your CCD and observe remotely from a warm room.

I started using the Planetary Live Stacking 2 months ago for Solar imaging. It is amazing. I no longer use Pipp or Autostakkert. Sharpcap basically does the majority of the post processing during the actual image capture. Once I have the finished Sharpcap tiff image I move it into PI. Using solar tools I then do the final processing. The real timesaver is saving the processing settings in Sharpcap and Solar tools in PI. I just open the final Tiff file and open the solar tools script and hit the OK button. I use the same saved settings for every capture. Tremendous time saver that producers a consistent final image every time.

Before watching this video I used to simply connect my NVG image intensifier with the eyepiece of my skywatcher Alt AZ Goto Dobsonian through my self constructed adapter to record video of some DSOs. Then I used to extract frames from the video and process them through DeepSkyStacker. Image intensifier gave me a real-time bright image of DSO almost equivalent to the one obtained after 15 second exposure from an astrocam. Tracking of my dobsonian is not good at all and that was my own idea to get rid of that problem using an image intensifier. Thank you.

Hopefully you can now use a camera with short exposures. Also, you can usually get better tracking by doing a really good job on alignment: Level scope, good reticle, entering date/time/location accurately, alignment stars separated by the right amount (not too little, not too much), using pointing accuracy enhancement on a star near your target, finish centering going “up and too the right”, etc…. It appears that most people who do all this can get pretty reliable 4 to 8 second exposures before stars really degrade.

I am hoping to get a clear night because I thought I was doing something wrong. I added 10mm to the 55mm recommended backfocus and the stars where still pointing to the center of the image at the edges. I guess the hotech 1x flattener f6-8 55mm back f was likely for the f8 refractor. Mine is f6.

I have found clear liquid silicone grease, I use on my fountain pen's ( Twsbi Brand liquid Grease ). when put on the threads for the joints dose aid in letting you get them apart again "Note only use it in very tiny amounts as you only need it on the threads. I apply it on one part first then join the two threads, this way I can't over do it right off the bat.

Fabulous presentation. Many of my thoughts parallel the speakers on exposure time.. maybe because we’re both EE’s, and me being a retired semiconductor engineer. I have never understood the argument that some make about many short exposures being just as effective as fewer longer exposures, especially on dim targets for the same reasons the speaker shared. I’ll have to think more about his read noise comments. Anyway, great presentation.

I agree with the comments below, one of if not the best noise/exposure/calibration presentations I've seen! I have one follow on question....if you process stars and target/background separately, is there any advantage, or disadvantage, to maximizing light frame exposure length according to the brightest part of the target and letting the stars blow out, then remove the stars during processing and replace them with stars from an extra couple hours of RGB lights exposed to optimize the stars?

I am hoping for alternate views on some of the anomalies seen, like Blair Cuspids casting 70m tall shadows w/square depression nearby, Flashes seen around Aristarchus Plato, Levi, Posiedonis. Alphonsus crater has historical glows and fogs across crests and around region. Medi Sinus shows Tower 5mi tall snapped by Lunar Orbiter {pic#”384M”} and other assorted questions that escape me just now. My problem is UNseeing the water-bubbles explode and flee out of camera when ISS is doing ‘live’ ISS feeds, or exterior shots of trusses where mice seem to crawl around beams. The gopher darting between ‘martian’ rocks is the best. As someone who used Photoshop before it even had that name I am very aware of color lookup table alterations and histogram f*ckery and simply do not trust NASA as anything but milspec propaganda arm.
