M81_M82 total time 75 hours
This image is from a Bortle 8 sky in Beaverton OR in my backyard in March and April of 2020 and spring of 2021. This felt like it was kinda like every man for himself! Haha, my first HaLRGB image.
I've been slowly upgrading this set up to improve my dual image acquisition. More image integration vs going to a dark sky and after all this I'm realizing that there is no substitute for dark skies. Its just harder in light pollution and exhausting doing LRGB especially.
Equipment details:
Two SV105T APO's with SV field flatteners and 3" SV focusers.
Baader 36mm filters LRGB and NB on one scope with 7 position FW and Baader 1.25" Lum and NB in the other with a 5 position FW
Two ASI1600mm cooled to -15C
ZWO OAG ASI290mm mini using Phd2
Mount: Takahashi NJP and ADM TGAD with Temma 2 on permanent custom 8" pier.
Pegasus Ultimate Power Power Box V2 for cable management.
Image acquisition with using APT dual camera mode and plate solving. CDC for pointing.
Polar Alignment with Sharpcap!
No auto focus yet but maybe someday.
Photo details calibrated with 25 darks/45 flats/63 dark flats:
Dithered every image and 2x drizzled
Lum 180 sec x 200 =10hrs in March 2020
Lum 60 sec x1500 =25 hrs in March and April 2021
RGB 60 sec x 420 = 7 hrs each channel or about in April 2021
H-Alpha 300x228 =19 hrs in March 2020
Total = 75 hrs ........I dont process my own data, it was painstakingly processed by my friend Tiago Narciso in Pixinsight and Photoshop. I kept feeding him poor data that was not always calibrated properly thanks to lazy calibration files on my part. Thanks to the DBE of Pixinsight the data was usable despite artifacts mostly in my color data which Tiago took care of! Thank you!!! I also wanted to thank Rey Hernandez who helped me figure out alot about dual imaging since he does tri-imaging from a similar light polluted site. Being able to get 10 hrs of data a night really helps!
