August 8, 2017: More disks in Ca-K and WL
I had beautiful clear skies in Fishers, Indiana yesterday morning, so got out the 80mm and shot a few more disks. Not much is going on in white light, just AR 2670 continuing its progress across the disk, but Ca-K does show some proms, especially in the part inverted shots, and more plage around the...

August 5, 2017: More shots from the USA, with Ca-K proms this time
Had another imaging session here, with the APM 80mm F/6, ASI178MM, and alternatively the Lunt Wedge with Baader Solar Continuum and Astronomik L filter to block the IR leak, or the Lunt Ca-K module. Seeing was pretty decent. I stacked 400 out of 4000 frames using AS!3, except for the prom shots, whe...

Re: Dual-band refractor interest?
For me the sheer size would mean I would need a new mount, and a place to store the big tube. For now that is out of the question. Should I later find a place for an obsy, I would certainly be interested.

Re: Dual-band refractor interest?
Interesting. I personally might like a slightly faster F/6.5-7.5, for use with my Baader TZ-4 and Solar Spectrum unit, F/8 os OK, F/10 too slow. One problem in Ca-K might be the fact that many Ca-K modules are rated to 4" aperture. Of course, correcting for CA is mainly an issue if you want to ...

I captured WAY too many SER files, because the seeing was all over the place, with fragments of cloud passing close to the sun as I was capturing the data.

I am currently looking at the ASI178MM as a lunar/solar camera for the faster Ca-K and WL scopes, and for the SolarMax-II. The s...
