I don't Graeme, There was a bright star in that general direction but I thought it was too far off-axis to cause that bright of a reflection. Very strange but it pops up every time I try to image the Leo triplet too.

@Graeme1858 I have been investigating this reflection issue some more and think maybe I've come up with the answer. It does appear to maybe be this bright star Zeta Oph (Saik) that is the cause of the reflection.
I overlayed the full frame image over a screencap from Stellarium. You tell me? I can't believe a bright star that far out of the frame would cause this kind of nasty reflection but here's what I found.

Looking back at my older Leo Triplet reflection problem. It also seems to line up with Theta Leo (Chertan) as the reflection problem. I never would have believed a bright star that far outside the fov could cause a reflection problem but the facts don't lie.

Hi AstroBee. I really enjoyed viewing your captures of the Messier objects. It looks like you are determined to complete the list sometime soon. Thanks for sharing your work with us AstroBee, and the best of wishes on your Messier Mission.

Thanks Marshall, I'm not sure how much longer it's going to take for me to complete it. I've been unemployed for over a year now due to C-19 but it looks like work here is finally starting to come back so I don't know how long it will take for me to get through all those Scorpius and Sagittarius objects, let alone all the other summer targets. I'm trying to work image 10 minutes of Luminance and 20 minutes each of RGB so that is 70 minutes on each target and if you look at the gallery you'll see lots of targets that I just did 10 minutes of lum or Ha on them from my light-polluted backyard. I'm thinking probably 3 years before I fully complete it the way I want to by replacing all those short placeholder images.

It's been over a year since I made an update here, I guess because the next bling is for when I finish all 110 Messier objects.
I'm not quite there yet but put a big dent into the list last night by shooting 15 Messiers rather quickly from my Bortle 8 backyard with a bright waxing gibbous moon nearby.
I started shooting 20x30sec Lum images on a few and then shortened them down to 10x30sec Lum images for the majority of the evening. I bagged Messier 9, 10, 11, 12, 22, 23, 25, 26, 28, 30, 69, 70, 72, 73 and M75 last night. That brings my total up to 98 for the list. Only 12 objects are left and they are all in the Scorpius/Sagittarius area of the sky. I'm hoping to at least get some short 5-minute exposures on each of these objects in the next few weeks.
