Thank you @larrychristianson2244. I have several more Nebula videos to do - but I want to setup for the eclipse this week as well. Hoping to capture a nice solar sequence throughout the event. Have a terrific weekend!

Another interesting post around a nice image David. Living at 53°N I tend to ignore the more southerly targets like M16, M8 etc. As from my location which doesn't have that many clear skies It can be difficult to capture enough narrow band data in the limited time available. Sagittarius and Scorpius are never in truly dark skies from my location for more than an hour. My favourite area of sky for imagining is from Cygnus to Perseus. There are plenty of DSOs to go for and they are usually visible at some time during the night throughout the year. I usually capture Ha data around full moon. I sometimes use this to enhance images taken with my DSLR or with a OSC camera, but to me nothing beats a true narrow band image when targeting emission nebulae.

Thank you for the feedback, much appreciated. Yes, those southern targets can be a challenge - even for me at 41deg lat... But, to your point, we have many DSO opportunities in the higher declinations! I too am a big fan of Cygnus and Perseus. I gravitate towards the Galaxy clusters - no pun intended! Cheers...

I worked on designing Hubble's super structure (frame) in like 1980. They didn't look through the mirrors before they launched was why it was out of focus. They actually didn't test it properly and my understanding was they depended on 1980's computer software too much to line up and collimate a Ritchey Chretien design, but no one actually looked through it. It's a long story, but the bottom line is that the company that built the mirrors didn't look through it and wouldn't work with Kodak. Now you know why they tested and retested JWST for months or it could have launched much earlier. My back porch points to the North by Northwest and Cepheus to Cassiopeia is one of my favorite areas to look at because it is convenient, not much light that way. That is an excellent photo of the 7822 Nebulae btw. How many stars did you crop out as I cannot tell if you imaged 7822-13, 14, 15 or all of them? Doggone Flamsteed numbers.😁 I'm glad you decided to image an area that not many AP folks do. Now go get a wide shot of Mu Cephei.

@MountainFisher - thanks for the Hubble context and behind the scenes background. Awesome of you to share. I've always wondered how in the heck did they launch without checking, double checking an triple checking the optics? Despite the human mistakes we tend to make, we do have incredible moments as well - like when they fixed it in space. Amazing... I will need to plate-solve and then check the boundaries of my crop to see which stars are in the FOV. WIll do so tomorrow out of curiosity and let you know. I'm glad you liked the image - I'm certainly a fan of this region of the sky! When I drop in the 90mm I will see about framing the Garnet star with IC 1396 - wide field it is! Cheers - and thank you for the share!

@@AstroDNAObservatory You're welcome. I didn't go the AP route, but certainly appreciate the skilled effort you invest in your photos and videos you share with us all.
