First image with M45 nebulousness via APP

Very nice!  Throw a t-shirt over the end and point it at a white wall.  Apply a flat or two and those dust circles go away like magic as well.  I feel your pain on 30s subs.  Stack the crap out of them, we must.

Thanks X. I did flats the first night, but accidentally unplugged the camera power and didn't take flats night 2. I'm going to re-process with a few more lights and Photoshop out the dust motes and re-post.

Looks great Greg !

M45 is one of my favorite objects 😉

Auto focus should be very good, I think that looking at the stars, the data could have been just out of focus, on the other hand, bad transparency can also be the cause off course.

Yes I think my focuser sags and slips I get it dead on with a bathinov mask and it turns out like that before long. I have a 3 in feather touch on the way also. 🙂

Ok, yes, I thought it was off, very bad weather can cause it to look like this as well though, so it's hard to be certain.

3"FT + motor focus... Great upgrades to look forward to 😉

Thanks Mabula, and for your SCC SAT tip. I reprocessed the Pleiades using just 117/400+ subs. SAT then set to  0.40 with  SAT Th at 0.1, and .....Star Color! It is all blueish from PS manipulations, but looks like I'm on the right track for good subs.
