Description
My backlog from the Spring is still alive, and I am glad to have it, since I cannot even remember anymore when I put my scope into yard the last time. It "looks" like that middle of October the Florida weather tides will turn, let's hope so.
After finishing up all possible Messier targets in Spring (2 more just posted last week), I still had some time left to go for some other targets, and this Arp one was for quite some time a desired object. Blueish tint, very unusual shapes, what is not to love with Arp269 😊? A bit longer integration time for the Lum channel, compared to my standard Messier integration times, and I think that one can see the differences. I am quite ok with the result, it screams though for a high focal length scope 😊.
Carpe Noctem!
