NGC 55 / C72: The "String of Pearls" galaxy.
#Seestar
S50🔭 16 min vs 20 min wall-clock. "Denoised" & adjusted brightness & contrast to bring out arms. Not included in the H400, so surprised me to see such a large bright galaxy. I like the differing densities and lengths of the left vs. right arm.

NGC NGC 2261 (Hubble's Variable Nebula, C46), imaged with a

S50 🔭. Pictures before & after using the S50's AI denoising and brightness / contrast settings. Imaged for Astronomical League's "Caldwell" observing program (

). 15 min @ 10 sec in alt-az mode.

Barnard 139 is the elongated dark patch near the center of the image. It looks a bit like a squid swimming down & left, with tentacles stretching up & right. The star field is quite dense: this is in the middle of the summer Milky Way.

Amazingly good image taken during the full moon. NGC 188 (also C1) was about as far from the moon as was possible, and i did tweak the contrast a bit to highlight the cluster stars, but still: this was taken during Full Moon!

M 11, the Wild Ducks, taken while i waited for it to get dark enough to try a Huge Mosaic of the Pipe nebula (which failed). Under some conditions, visually in a modest sized telescope, M 11 looks like a V of waterfowl (which is where the "Wild Ducks" came from).

I like to take very short exposures of objects with the
#Seestar
S50 🔭, to approximate what you can see through a modest (8-10 inch) scope. Well, those are modest sizes nowadays, given the prevalence of foot-wide and larger scopes. 30 seconds on most objects is about right.
