Yes, it seems only two distinct values are assigned to the core regions of bright stars. The max value to the 'inner core' and then just one slightly lower value out for a distance surrounding it. It feels weird to realize how much time I've spent chasing an optical illusion (usually with fuzz in SV...

Last night was clear but very moony, so I just shot a few hours of M3 with the AT130EDT+IMX571c. I stacked about half of the subs, which all had FWHM at or better than 2.3" - 220x45s Low-Conversion Gain (gain 0 to you ZWO folks). The brightest star in the frame is mag 6 (which is possibly related to...

If I work another 30 years I could stop with the whole "retirement savings" thing all together and just blow it all on astro gear! Brilliant!

Thanks to the M106 thread, I now have 3(!) followers on astrobin. More importantly, I learned from Stefan's abin profile that we are both biologists in our non-astronomy time. Though I hope to retire soonish to become a full-time cloud-complainer.

I was of the understanding that one shouldn’t switch midway through processing in ST and use other software as ST is actively tracking the data from start to finish until saved. I only thought one could tweak ST with other software once completed in ST as ST would be compromised and not provide opt...

Thanks for your like, Ron! ;) So now you have two followers in total, Mike and me. If you want to get likes, just drop me a line. ;) I've often wondered if part of the game is to Follow a bunch of people in hopes a few of them Follow you back, increasing views and Likes. That's pretty exactly what ...

AndyBooth Very nice - thanks for posting that! Do you know if the Altair 130EDT uses the same glass as the AstroTech, or the upgraded glass as in the TS version? I suppose, with the triband filter, it would not make much difference for you. Some day I'd like to see someone with that type of filter ...

I was able to get out to the club dark site Monday night (having the week off from work). I had my SQM with me for the first time there, the sky measured 21.06 - quite an improvement from the backyard (18.9-ish), though nowhere near "dark" to anyone with access to really good skies. This was also th...

Quite nice, Dietmar! I hope to image this Spring a similar field with the AT130EDT. I'm encouraged by the nice details and rich colors you got from only 3.5 hours. Roughly converting in my head from your f/5 to my f/7 and your B5 to my B6/7, I should be able to get a decent image in maybe 20 hours.....
