Hi all it was a decent night last night a little high thin cloud ,but hey take the chances when ya can both M27/45 were both
Around 1hour 10 mins worth of light frame data ,i used stock darks bias and flats (which did not work out well at all) heres the details also yhe fl of my scope is 950mm would a reducer be any good and what size i only have dslr's tho?
5" Edt frac
Cannon 600d- huetech idas type 2 LP filter
80mm optic star gold 80mm- qhy5 guide cam
Old laptop
All mounted on the Cgem goto on the pier
I had to throw about 25 subs from each run because of high thin cloud what a pain but hey ho
Here they are these took some playing with after as the noise and cloud killed them

Much better pat,

You are now bringing out the full extents of M27 with the longer imaging runs.

What length are your subs?

The might need to shorten them to reduce the noise? Also a delay between exposures helps the sensor to cool down a bit between subs.

Clear Skies

Sorry i forgot to to include
12x5mins
Iso 800
I left around 20 secs between subs ,i had to throw about 25 away on both runs due to clouds and to be fair the subs ,i did stack could have been better i also used some flats i had took the other night they may have killed the run ,but every one is a practice ,and the guide was brill every thing worked .
I have only had this image rig a year or so and 5 months of that a was lay flat i did my back lifting the 12 reflector ,but you might be right the sub lenght. Might be better at 180 secs instead of 300
