The Pleiades (M45) in Taurus - Mark II

All,

This is all I managed at Lostock this year.

10-minute exposures on an uncooled DSLR are not the way of the future. Though, I am reasonably pleased that the G-11 is capable of carrying the 5" APO as well as the 80mm ZenithStar with heavy mounting plates, camera and guide camera.

I will re-attempt this leading up to, and, after, culmination, with half the exposure length but with many more sub-exposures.

So, please ignore the noise if possible. I think the faint stuff towards the middle may be galactic dust? It looks like noise, though. I'm not sure.

Oh, and diffraction spike haters need not look. Unlike lengthy uncooled camera exposures, diffraction spikes are the way of the future.

Read and view here.

Comments, critique, lynchings, etc., all welcome.

Regards,
Humayun
