Observing: Imaging the Moon & Jupiter with DSI
Checked the 40D + MaxView DSLR rig on the Antares 127mm again, this time with the TV32mm Plossl just to see if my focusing problem is caused by the Celestron eyepiece. It isn't - the same deal. I'm wondering if it isn't as simple as a field-flatness issue with the Antares that might be corrected with a add-on field flattener. Next time: TV85.
I packed in the 40D and broke out the DSI for the first time since I bought it. I just tested it with the new version of Nebulosity (2.0) in the living room yesterday to get comfortable with it, though I still need to read and absorb the Nebulosity manual.
First target: The Moon. With no idea what I was doing I captured a few shots of the area around Tycho and the southern highlands. These were single exposures, not stacks, and I used the Tele Vue 2.5x Powermate to bump up the magnification. I think I'm going to like this DSI thingy...:
On to Jupiter, now getting low in the west. Had a bit of a time focusing, so need to play with the DSI/Nebulosity combo a bit more to make sure I'm using it correctly. This was the best of the 6 attempts. I shot 100 frames, used Nebulosity to demosaic, normalize and convert to TIFF, then stacked the best frames in Lynkeos. Finally brought the image into Photoshop for some level adjustments and a tiny bit of sharpening. Still not what I want, but an improvment over previous attempts...
