A few Moon shots - 17 March 2016

[geoflewis]

Seeing as the Moon was up and I'd set up my 10" rig for what turned out to be an underwhelming try at Jupiter I thought that I might as well slew over to the moon and grab a few close ups...

They are a bit grainy (from shooting through fog I think), but turned out better than my Jupiter.... Thanks for looking.

Nice set of images. Thanks for posting.

I like these, the first image of Plato and the Alpine Valley is really nice. Well done.

Thanks Alan, like many DSO imagers I tend to stay inside when the Moon is up, but I should just image it more often as its usually a treat when I do. Plato is probably one of my favourite craters (well it probably is for most people), but I particularly like this version seeing it set in a wider field setting than just zoomed right in on it which is what I'd usually do as per below taken Jan 2015....

There's a few nice ones here and there close ,they look like the gain was a little high to me there's a bit of noise ,focus looks a tad off ,but they look great fork the conditions

Thanks Pat,

The gain was pretty low at 375, but you may be right about the focus. It may also be a bit of atmospheric dispersion as I was using a colour cam and I think that I sometimes get better results if I throw away the blue channel, or just use red or green channels (green gives me 50% of the pixels). These were quick captures at the end of my Jupiter session and then a quick and dirty process, so maybe I should take another look at the data. They came off the camera quite dark, so I pushed levels to brighten them which also may have increased noise. Thanks for looking and for the feedback.
