Description

I finished off processing the entirety of M33 in Ha & OIII with RGB stars. It was a fun project series. It's not the most picturesk, though, however I learned so much about M33. Especially with the amount of OIII in some of it’s nebula; many nebula with more profound OIII than within our own Milky Way. Previously I submitted three heavily cropped areas I thought were of great interest trying to see how much detail I could pull out on such small nebula visible here from Earth. The data was drizzled overall including in this image, so my image scale was cut in half as to what it normally is at 0.68"/pixel with my ES 165mm APO and ZWO ASI1600MM Pro. In capturing M33 in HOO, it wipes away the rest of the visual band pass leaving only the profound nebula located within M33. That was crucial to me to see what was really going on with the nebulosity within M33. Feel free to zoom in to the higher resolution. There are so many little curiosities to be seen.
