Focal Length Comparison, main image is shot using a 2x Barlow and a Kenko 1.4x to give 2,800mm f/14 1/125a @ iso 320, inset is at prime so 1,000mm, f/5, 1/500th, iso 100.
The main image is from 7 stitched images as this set up gives some vignetting.

A couple of older moon shots from 2012 click side arrows to see each one.
Image from April 2012.
I ended the evening with a couple of shots of the Moon at prime focus, 650mm. Not as much fringing on these as on the ones from last week so I must be be getting the collimation close.

This is the oldest moon i have ever caught by camera, quality isn't very good as the tube had little time to cool, and that the moon was less than 6° above the horizon.
