M 31 with 6" f/4 Newt

Posted By Steve Mathis
I guess I'll never get tired of trying this target.

This one was made with a Nikon D50 on a 6" f/4 Newt, made with a Coulter mirror circa 1971 ($39.95). 26 x 6 min, ISO 1600. A Baader MPCC was used on the 6" f/4. This is a full frame image. DSS, PSCS3 used for processing. Thanks for looking.

Jupiter 11-23-11

Posted By Steve Mathis
This is my first attempt with half-way decent seeing, maybe 3/5 at times. C11 and 2x Barlow, ToUcam Pro II. 250 of 1100 frames. Based on Andreas' image from 11-7, I have a long way to go! Focusing is tough when the seeing is average.

Solar scope + ToUcam = fun

Posted By Steve Mathis
From about 11:30 CST this morning. Two AVIs, one for the disk, one for the prominence, longer exposure for the prominence. Really crummy seeing. Still fun, though!

A good day with the ToUcam

Posted By Steve Mathis
Mars and Saturn this morning, C11 + 2x barlow, and a solar mosaic around noon, 40mm Coronado. Seeing is everything!

And a good night...

Posted By Steve Mathis
The seeing was still good here last night, so Jupiter was the target. ToUcam, C11, 2x barlow, AVIstack, PSCS3.

Jupiter 12-16-11

Posted By Steve Mathis
Last night, with my C11 and ToUcam. Jupiter and Ganymede. I tried 30 fps on this run, 2700 frames, keeping 400 for the stack. I also tried a 4 point align with Registax 5. Seeing was a little above average.

Lunar Mosaic 12-17-11

Posted By Steve Mathis
This is part of a 16 panel mosaic taken Saturday morning. ToUcam and C11, AVIs stacked with AVIstack, stitched together with PSCS3. This is reduced to 80% of the original scale, and shows about 60% of the whole mosaic (the good part along the terminator, from Clavius to the Straight Wall).

Jupiter 12-17-11

Posted By Steve Mathis
Here is another ToUcam/C11 Jupiter. The higher frame rate makes focusing easier it seems. Seeing was not great generally, but settled down during this run. I think it was my third or fourth "I'll just do one more...", and was the best of the evening. There is a lesson there I think. Processing with AviStack and PSCS3.

Lunar Mosaic

Posted By Steve Mathis
Another mosaic with my ToUcam and C11. Sunday, Jan 29th, 45 frames, stitched together with PSCS3. It took about 45 minutes at the scope to get the AVIs, then all day yesterday for AviStack to process them. A couple of hours this morning to put it together. The image here is 1/4 scale of the final product. Thanks for looking, comments are welcome.

Copernican Sunrise

Posted By Steve Mathis
From last night, ToUcam and C11, a 4 frame mosaic. The right-on-the-terminator contrast is sort of hard to deal with, and we had a 40 m/s jetstream overhead.
