My 1st attempt at the Rosette Nebula last night
30 x 5 minute subs ISO 800
15 x darks
Canon 600D stock
HEQ5 mount
PHD2 guiding around 1.3 arc sec error
Stacked in DSS
A rushed processing in Startools
There’s heaps of faults with this image but I’m stoked just to capture it and show the open cluster plus reveal a bit of nebulosity
The Canon 600D was struggling with high ambient temperature and an internal temperature of 36 deg C , so heaps of read noise and everything else that goes with it ( horizontal banding etc )
I set BYEOS with a 5 second delay and pause to help with the temperature but I don’t think it did anything
In hindsight I should have shot 50 or 60 shorter subs, say 2 or 3 minute
ISO 800 is about the right sensitivity for this camera on most DSO’s
Comments and criticism welcome
Cheers
