This is my longest integration project to date. A total of 377 subframes culled from over 600. Individual exposures 240 seconds (25+ hours total integration).
Explore Scientific 102CF with 0.8x Stellarvue reducer/corrector for an operating focal ratio of f/5.6. Mounted on Skywatcher EQ6-R Pro with PHD guiding.
ASI 1600mm pro, cooled to -10C, Gain 200, offset 50. Processed in Pixinsight. All from my backyard over the last few months.
I may have to start thinking about getting a faster scope if it takes me almost two months to acquire a 25 hour image.
