Description

Messier 35

@ 250 mm, f = 14.0, ISO 1600

27 x 90'' Light

18 x 90 '' Dark, no Flats, no Bias

Stacked by DSS 2xDrizzle, finalized in Fitswork

Telescope mount = SkyWatcher Star Adventure

Canon EF-S 55-250 mm f/4-5,6 IS is a (as I think) difficult Zoomlens for the use in these cases. With a focal length of 135 - 160 it is very sharp by lower aperture round about 5.6. Here I use the max. focal length of 250 mm, therefore I increase aperture to 14.0 for sharp images so also ISO need to be higher and noise become a bigger problem.
