Tried last night to image the Crab Nebula.

No luck really ... am I expecting too much from my Canon 80D (not modded) and 70-200mm f2.8 lens  iso 400 in a Bortle 6 area ...... AZ-GTI in EQ mode .....  would the 150-600mm at f5.6 be any better.

Probably.

Crab is small object and you need larger telescope to properly image it.

With 200mm lens and DSLR - it will be less than 100px wide in the image. Even with serious gear  - you can't expect it to be much larger - at best around 350px

However - you should be able to detect it without too much trouble with that setup - it is bright enough.

Thanks for the reply .... yes it was very small and stretching did bring it out but no clarity really ....... I also imaged the Rosette Nebula same night and that was sooo much better.
