Training for the Moon – December 2017

Scroll down to content

The following image shows just a segment of the Moon, acquired in December “last year” (already).

It represents my “first-light” test of the APM Coma Correcting 2.7x Barlow. Unfortunately, the image is far from what a 14-inch scope can do, and this was due to bad seeing (some fast westwind also). The shot is cut from a larger mosaic made up from 4 areas only.

It appears that this lens actually does what it says it does: corrects the coma of a F/4.5 Newtonian, and quite good actually! It paves the way for a full mosaic of the Moon…

Setup for the image: 355mm F/4.5 Newtonian, APM CC 2.7X Barlow, Baader Red filter, ASI 1600MM. Image resized to 70% (poor seeing).
