SH2-284. Originally Published February 17, 2022

 Yesterday, I posted an image of NGC 2282. In the bottom left corner of that image is an area of nebulosity, SH2-284. Sh2-284 is often overlooked as Sh2-285 (the Rosette) is a close neighbor. They are, in fact, part of the same molecular cloud. This image is a bit of a fool's errand--imaging a faint object under Bortle 9 skies with a full moon, slight haze, and f/2 optics! The solution to produce a workable image is to stack many short exposures--in this case 500 x 7s. Interestingly, the image I posted yesterday of only 100 or so images of NGC 2282 shows what I think is a better image of part of this object, probably due to sky conditions.

16 hour integration of the Heart Nebula with the Dwarf 3 telescope

The Heart Nebula can be a challenging object due to its low surface brightness, especially in my neighborhood where I image under Bortle 8/9...
