M45 star test
Last night I ventured out to the Liverpool Astronomy Society's Leighton Observatory (Pex Hill) to finally join the society and see what the turn out was like (especially since BBC stargazing live!)
Lots of people, many quite interested by my pile of kit hence little amount of imaging but at least it was a good social visit.
Managed to test out the new Skywatcher Equinox 80 APO PRO telescope.
The field flattener is on order and not arrived yet so thought I would test out the field curvature anyway.
As expected the image is flat for approx 75% of the image circle.
Not bad at all!
Its so nice to have round stars in the centre of the image and no diffraction spikes caused by lens apertures.
Colour cast caused by the use of the Astronomik CLS Clip filter used to combat the excessive light pollution.
Fullframe, no crop.
