    The Bubble Nebula (NGC 7635) is an HII region in the constellation Cassiopeia. Its iconic “bubble” shape was created from the stellar wind created by the intensely hot central star (SAO 20575).

    Also designated Sharpless 162, and Caldwell 11, this unmistakable emission nebula sits within a giant, glowing molecular cloud. The Bubble itself is about 10 light-years in diameter. I was able to capture those detail;s with an integration of 613 10 second sub exposures using a Dual Band filter and the CovalENS mosaic mode. The globular cluster M52 is also evident:

    If you're not doing anything Friday at 6PM UTC, that's 10am PST, iTelescope is offering a webinar.
    They're free and often, very interesting. That link will take you to the registration page as well as upcoming events. You're looking for "What we can't see in the Universe" for Friday. More often than not, speakers are graduate students studying the subject they're presenting.

    This image represents over 4.5 hours of combined integration using a Dual Band filter and the CovalENS mosaic mode. 4 Separate mosaics of the North American and the Pelican were combined to form this panoramic image.

    well I watched the sky off and on all night, and never saw one Geminid meteor. It's supposed to peak tomorrow night, so I'll watch for it again.

    Good luck tomorrow! I saw a lot of them, one was a potential fireball (very bright and colorful). Although it was 20 deg.F out so I'm still trying to warm up...

    Veil Nebula. 454 sub exposures, CovalENS Mosaic mode, Dual Band filetr. Very cold and no moon really made a difference in this target that's been imaged previously.

    It was very cold so I was reluctant to head out to a dark site at 1:00AM. So I quickly set up on my deck with a limited view of the southern sky. I lucked out and got this shot at 3:11AM !! Shot with my iPhone and NightCap.

    Playing with my mirrorless camera. This is a high resolution star trail image which was created with just about 400 10 second exposures somewhat centered on Polaris. I selectively removed most images with any plane trail artifacts to get this somewhat clean image. This was taken from my deck, I need to get to a more scenic location and repeat this. I used StarStax to assemble the images:

    Very cool. Easy to see just how much air traffic there is, even in the version you cleaned there

    The Witch Head Nebula in Orion. Just about 105 minutes of total integration (10 second sub exposures). No filter, CovalENS mosaic mode. Half moon and encroaching trees made the imaging very difficult. I was able to eek out this image...

    The Orion complex region, very prominent Orion Nebula and the Flame Nebula. 56 5 second stacked but untracked exposures. f/4, ISO 2000, 105mm aperture. Light pollution from street lights. Taken with my camera and processed with Astro Cooker and Affinity Photo 2.

    I'm impressed. The 500 rule says that shouldn't be possible but here, you have a great result.

    I think that maybe you misread my post. I took 56 5 second subs and then stacked them. The 500 rule gives just about 5 seconds...

    Usually that close to the limit and you start to see trails.

    Sorry, got it. Actually I was pushing the limit as there are some trails when I zoom in...

    Orion, the Pleiades, and the moon(caught between trees). 25 6 second exposures stacked (no tracking). Gave up early as it's ~9 degrees F right now. 50mm, f/4:
