My first try on this object. That is M52 at the top edge of the frame. 13 x 10 min, ISO 1600. Modified Nikon D50 w/ Baader MPCC. 8" f/4.9 Newt on a G11, guided with an ST4 on a piggyback ED80. DSS and PSCS3 for processing. Again, comments are welcome!

Today's Sun

Posted By Steve Mathis
Nice spots. This was sort of an experiment to see what would happen if I attached a Nikkor 2x teleconverter to my D70, then to my ED80. It seems to work OK! Nice image scale on a DSLR. Registax used on 25 frames, ISO 200, 1/4000 sec. Baader solar-film filter.

Eclipse

Posted By Steve Mathis
We had high clouds passing through, but enough clear patches to get some images...this is a montage of 3, beginning, middle and end of totality. Nikon D50 through an Orion ED80 with 0.8 FR/FF. Assembled in PSCS3. Thanks for looking, comments welcome.

M33 with an ED80 and D50

Posted By Steve Mathis
I just wanted to get lots of letters and numbers in the title. But seriously, this is 11 x 10 min @ ISO 1600, with an Orion ED80 with the "dedicated" FF/FR, so it is a 510mm FL @ f/6.38. Stacked with DSS, and processed with PSCS3. Help revive this forum, and comment or criticize at will.

Wide Taurus/Perseus

Posted By Steve Mathis
Taken with a Nikkor 50mm f/1.8 manual focus lens, at f/4. Modified Nikon D50, 13 x 10min at ISO 1600. I was hoping for more detail in the dust.

Frost Flowers

Posted By Steve Mathis
Or ice ribbons...formed when water is wicked through cracks in the stems of certain woody plants, and then freezes. The are quite common in the woods of SE Oklahoma this time of year, but this example was pretty striking!

Storm on Saturn

Posted By Steve Mathis
I was observing Saturn this morning with a 10" Dob at 203x, and could easily see the bright white storm in Saturn's northern hemisphere. Has anyone else seen it? The seeing here was surprisingly good, and I had the scope out with the fan running for an hour before observing. It was a pleasant 21° F out, with a light wind.
