Aristarchus

Hello folks,

This image of the crater Aristarchus taken last week (3 Nov). I was experimenting with the handicam exposure controls to try and reduce over exposing on the brighter regions. Lowest gain at 1/25 sec with a 10 mm eypiece is still too bright. This image taken with 10 mm + 2 x Barlow and 1/250 sec. I forgot to check the gain and it auto set at maximum 18dB so the image is a little noisy (Neat Image fixed most of it) . 190 frames stacked in registax4 with single alignment point on the crater itself. GSO 10 inch, hand held afocal, seeing about 5/10.

Hoping to get Mercury transit Thursday morning but forecast is 992 mb and rain.

best wishes Mike
