Looks great for such a little scope. Nice details. Good color punch. It's great your getting those clear nights. My location on the other hand has just been pummeled by a Bomb Cyclone and I am still waiting for power... I envy you.

This is a small part of Perseus Molecular Cloud flare region in the constellation ARIES, which is just west of the of the Embryo Nebula. This region includes a compact trio of dark nebulae (B202,B204,and B206) amongst others and bright reflection and emission nebulae.

Stellar region in the constellation Cassiopeia. This photo is my wide field exploratory shot of  an area that contains reflection and dark nebulae, open star clusters, and HII regions. If weather cooperated I was planning to investigate some areas further with my narrow field of view scope.

- The weather never did cooperate, maybe this summer I will shoot some of the interesting areas with a narrow field higher res scope.

Set up:
Telescope: SVBony SV555 Petzval Astrograph
Camera: ASI2600mc pro
Mount: ZWO AM3 mount
Filter: SVBony UV/IR cut
Controller: Mini PC running NINA and PHd2 acquisition and guiding software.

The Surfboard Galaxy (M108) is a barred spiral ~ 46 Mly from Earth in the Ursa Major constellation. The view is almost edge on giving it a surfboard appearance. It contains a massive black hole in it's center about ~8x larger than the Milky Ways (Per Wiki).

This object is very dim. I had my scope stare at it for 10 hours just to get enough signal for this photo. If I do another 10 hours the bat might be easier to see.

There is a bat in there. I had to look that one up to find it. The wings extend outwards from the center I believe...

The Flying Bat Nebula (SH2-29) and the Giant Squid Nebula (Ou-4, ),and  the Dark Seahorse Nebula (B-150) in Cepheus at ~ 2300 ly distant from Earth. This is a winters day update to a previous post. Taken last June and reprocessed with some newly acquired tools.

The scope exposure period was 10 hours over 4 nights for this photo.

SH2-140 is an emission nebula. Some refer to it unofficially as the Peak a Boo nebula because it is partially blocked by dense clouds of the Cepheus molecular cloud complex. It is a stellar nursery where dense clouds glow illuminated by UV radiation. (per Wiki).
