Combined 10s, 30s, 1 min and 5 min shots. About 3 hours I think, I can't remember, using Canon 60Da at ISO 800 and sensor cooled to a lovely 26 degrees celcius and W/O Flt 110 with darks and flats applied.
Just trying my masking but need to revisit this again. Comments welcome.
No way Sam. Great scope the 98 and you should pull some lovely widefields from it. I can't wait for christmas to be over so I can get the scope out and go for it.
