A partial replay of a few nights ago, with the roof very stiff to open. As I heaved and pushed it eventually came free and rolled to the other end of the shed with a booming shriek. Dogs in backyards around began to bark, and my next-door neighbour’s lights snapped on. I sat quietly until the rest of the world calmed down, and at some point I shall have to make a peace offering to my neighbour. Yikes!
I upgraded the laptop on Thursday, and tried capturing Mars again on Friday. The capture was snappier, but capturing using a Quicktime movie still only gave me a 19.9 Mb file. On the other hand I was able to capture 400 images in batch still mode, and after some processing this was the result:
or as a double sized version (the processing is very slightly different):
As usual this is captured with a 5x Powermate on a f6.5 110mm William Optics FLT-110. Time was 4.21 -4.25 EDT, or 8.21 UT, so the Central Meridian is 307 degrees.
I’m always bothered when I see a bright ring at the edge of a planet – it seems to me that it’s a sign that the image has been over-processed, an artifact of the sharpening filter. You can see such a ring in the smaller Mars image, and I’m considering reprocessing the image so this does not appear. Any comments — either way — would be appreciated.
Oh, and closing the roof was a smooth and quiet operation, with no uproar. Daylight opening and closing has been without incident, so I suppose I’ll just have to wait till next time to figure out where any noise is generated.
