I thought that also but would i still be getting Coma at f5.6 on a 35sec exposure?!?!  The 50mm nikkor i know is bad for it, but the 28-200 is an aspherical lens which i swore were better for that. 

Hi!

New to imaging but have been having some success recently with Rho Opuichi. However, im having an odd issue...fan shaped stars.

Ive stopped down the lens, used a different one, same issue. Anyone have reason this could be happening? 

Gear: Canon T5 unmodded plugged into laptop, AzGti mount in Eq mode - wifi connected to laptop. Rho image was using a Nikkor 50mm 1.8 lens attached with an Urth adapater set at F4, Iso800, 60 sec exposure (13 used in stack). Lagoon image was using Aspherical 28-200, F5.6, iso1600, 30sec exposure.
