Hi all:

This is the first light image (8/22/09) using my new, home assembled, 80mm Ha system. The filter is a rear mounted Solar Spectrum Solar Observer with 3A bandpass and 25mm clear aperture. I have more details about the telescope and filter here:

My new telescope is really nice for visual use too!

I processed this image by faithfully following the tips and techniques taught by Paul Hyndman. His web page is chock full of useful information. I am sure that I will improve a lot with practice, as we all wait for the sun to become more active. Still, I am very pleased with this first light result. It would have been terrible without Paul's "virtual" help. If you know Paul, thank him for me!

My camera is a FLI Microline 11002M. (It works at night too!) I was operating at -20C which is pretty good considering that the temperature was in the 80's F when I took this image. The disk was captured at .02 second exposure. The proms (such as they were) were captured at .18 second.

I hope you like these, Jim

Here is a crop of the lower left quadrant. I was not paying attention to determine if this was for sure NW or SE... Other than the cropping, this is the same image as #1

Killer proms, Jim. grin
All kidding aside though, that is an awesome shot.
Solar activity was picking up there for a while,
but the last few weeks have been...well, quiet. :S
Looks like you're ready when things rev up again.

Impressive. Lots of detail.

Are you sure that's not actually a canteloupe??? smile
