Description

First light on the 4 lens F4 Aplanatic coma corrector and a last hurrah for a couple of months as astro dark disappears at my latitude.

Still a little work to be done on obtaining 100% backfocus but for a 2.5h exposure happy with this one - indeed first image that I am happy sharing coming from the 200mm F4 newt. It has been a very steep learning curve coming from a redcat! I know now how forgiving petzvals are - any body got a FSQ106 that they want to give me?

Description: Recalibrated the subs as I noticed a bad reflection pattern in the background... sorted that and things seem to work better
