Description

M31 - Rokinon 135mm - 2600MC - Antlia Triband RGB Ultra Filter - 5.25hours  Robert Moses State Park Long Island 11/12/23, 11/14/23, 11/19/23

2600MC - Gain =100 - Exposure = 60" With Antlia Triband RGB Ultra Filter.  Guiding around .3 - .7 arc/sec. Dither every 4th sub.

Shout out to @Elmiko for his 2021 M31 image with The Rokinon/Samyang 135mm which I used as a color reference. I must say getting the blue to come out in this image was tough but I think I did ok

Should I crop more? I want it to be a widefield but im not sure if it's too wide... Does the detail show well at this FOV?

Thoughts from the night:
Another image using the Antlia Triband RGB Ultra Filter. While waiting for my main targets to get into position over the course of 3 nights of imaging, I decided to take subs of Andromeda with the Triband for the community as another broadband test, as well as to not waste precious imaging time and get an additional image while I waited. These subs were taken from the darkest part of the sky at the zenith.

This is 5 hours 18 min @ f/2.8 using 60 sec subs. For such a bright target at this fast focal ratio I felt this would be a good test of the Triband as M31 is the probably the most imaged deep sky object and is a quintessential broadband target. 

I felt that the filter performed very well with M31 but as mentioned in previous images, I feel anyone interested in this filter should increase integration times for broadband targets by a factor of at least 2x. I also feel that this filter, having much narrower bandpasses than a UV/IR cut which lets all visible light thru, brought out the Ha regions much more than a UV/IR cut filter alone would have. I did enhance them for effect, but they were distinctly visible prior to enhancement. That was a welcome surprise.

I have 2 more images to go with this filter. Spaghetti nebula and Rosette/Monocerous Complex. I'm getting serious processing burnout lol. 

Please tell me any thoughts or improvements I can make if you have a moment. It's appreciated.
