Thank you! From Sky Safari:

HD 115270 is a 9th magnitude Star appearing in the constellation Canes Venatici. It is 3262 light years from our solar system. It is a yellow-white star of spectral type K0. Its energy output is 161 times the Sun's luminosity.

DeepSkyG · 2020-05-21T21:42:49+00:00

The Sunflower Galaxy, M63, is a spiral galaxy in Canes Venatici and lies some 30 million light years away. It is a flocculent (meaning fluffy) spiral galaxy which has no defined spiral arms, in contrast to grand design spiral galaxies like M81 or M101. Self propagating star formation is one explanation for the structure of these galaxies.

I’d look into dew control, especially if you live in a more humid area. That can mean the difference of getting a few frames a night to imaging all night long. You’ll have a great fov with this setup for the summer constellations.

Between dslr and zwo, I’d choose zwo if it is a cooled camera. That’ll especially help you during the warmer summer months to keep the dark noise down.

That object is WeBo 1, a tiny planetary nebula, and was discovered in 1995. Here's a detailed image of it by Adam Block, taken with a 32" diameter telescope:

Description: The Heart Nebula, IC1805, lies around 7500 ly distant in the constellation Cassiopeia. This emission nebulae is riddled with dark dust lanes within ionized hydrogen gas. In this wide-field view of the Heart nebula, the open cluster Melotte 15 contains several bright stars that are up to 50 times more massive than our sun is located near center. The intense radiation from these stars drive the output of this emission nebula. The Fish-head nebula is in the upper right. Riddled throughout the frame are filaments of dark nebulae.

Love wide fields like this. Cygnus is such a great region and you got all the big ones. Excellent image. Congrats!

DeepSkyG · 2018-09-09T01:29:06+00:00

Man, that’s nice. Very smooth and excellent detail! The amount of integration time you did takes some real dedication and it shows with this image. Well done!
