That is a great image - I love one frame disc snaps - the Skyris looks like a great imager for your setup!

Thanks guys! Interesting to see the northern belt begin to weaken for the pole shift. I was not into solar astronomy 11 years ago, this is my first time seeing it.
Right there with you. Fascinating stuff.

The camera itself works well, it's a Sony Super HAD ICX274 Monochrome chip, which is a safe bet for solar imaging. No newt rings to report (but I did not use it with a barlow either). The image is noise free and no bad, hot or white pixels to report on the camera.
As with most cameras, the real reporting is with the software. I am familiar with ICAP with the NexImage 5 camera, so there were no surprises there. The ICAP software has all settings on automatic when freshly installed on a PC, so the exposure and gain setting had to be set to manual to use the camera without over-exposing the sun.
Registax readily handles the .AVI videos and processes them nicely.
The camera chip size is 8.50mm x 6.80mm (roughly 11mm diagonal) so can easily work with B1200 without severe light drop-off on the sun. The resolution is 1600X1200 pixels (2 Megapixels) so you can make larger prints with your solar system images. The pixel size is 4.40 microns, so even at 12 bit A/D Conversion, you still have sensitivity for solar surface details and flares.
The chip size allows for full frame images of the sun in the Lunt 60mm and I suspect 80mm scopes. I don't like putting together mosaics, so a full frame image of the sun is just the ticket for me. I've ordered a Lunt 80mm APO scope for larger full frame images with WL, Cak and moon shots.
Only had 1 day with the camera so far, so I will report more later.

Amazing pictures! Thanks for posting them, and for the report.
Just looked for it over at Celestron's web site, but they don't list a Skyris 674M; there's a camera there with exactly the same specs (specially the resolution, which seems to be the difference between models), but they are calling it a 274C, not a 674C. Could it be that Celestron changed the model number?

*edit* wonder if that makes the 674 a "limited issue" collector's item?
