Managed to test AP CCDT67 0.67x focal reducer, works quite well with obvious vigenetting as the distance was nearly 120mm (2" adapter + Orion OAG + Tmount + 550D), more than the 101mm recommended.

Still had a lot of trouble with the Orion OAG, esp on focusing and finding a guide star. There were high clouds and a bit of light reflection pollution, so could only take a few subs.

Scope: LX90 8" ACF, with AP CCDT67 reducer
Mount: HEQ5
Guiding: Orion OAG+SSAG
Camera: Canon 550D (unmod)

NGC2070
5x2mins, 2 darks, ISO800

NGC253
2x5mins, 2 darks, ISO800

Stacked with DSS and post processing in Photoshop. I resized and cropped the original image in order to attach here.

Not too many frames with a green laser beam in them, then? :ashamed:

Thanks for the feedback guys..

I think I had a faint streak in one of my ngc253 subs :) must have been that laser! luckily that sub had elongated stars so I discarded it :)
