Re: Autofocus

Yes. Look up: Automatic Focus Scanning in the documentation. I use the Celestron autofocuser via ASCOM and have used the Moonlite autofocuser in the past and both were detected by SharpCap and work very well.

Re: Nebulae in H-alpha, part 1

Thanks much, Dave. Yes- getting the C11 to play nice along with PHD, OAG, the dew issue we already discussed, etc. has made it a challenge (sometimes fun, sometimes not so fun)- especially being 12ft off of the ground. After about 12 months, I have just about everything automated so rarely need to g...

Nebulae in H-alpha, part 2

A few more using the Astrodon H-alpha filter with a ZWO ASI 1600MM Pro cooled at -10; gain 300. Taken with a C11" EdgeHD @f/7 and stacked 300s x 4 (20 min total exposures) using PHD2 guiding.

Also have a nice Cresent N but could not reduce it enough to post.

Nebulae in H-alpha, part 1

Had a decent night with above average transparency & seeing but 98% moon illumination. So, time for the Astrodon H-alpha filter with a ZWO ASI 1600MM Pro cooled at -10; gain 300. Taken with a C11" EdgeHD @f/7 and stacked 300s x 4 (20 min total exposures) using PHD2 guiding.

Re: Live Stack Mosaic Horse and Flame

With my C8, I use a dew shield + 2 dew heater bands otherwise I am misted out very quickly. I am located on the west side of the Pennine Hills, UK. All the cotton mills were built here during the industrial revolution because the damp climate stopped the cotton snapping when it was being spun. Taki...

Re: Live Stack Mosaic Horse and Flame

Similar to me as far as Bortle 5/6 skies. I also have a dew shield and dew heater as my C11" SCT is a dew magnet but even with that, I have many nights (like last night) that the humidity overwhelms the system. Yes, indeed. The Optolong L-enhance filter is a top performer. I've been using it the pas...

Re: Live Stack Mosaic Horse and Flame

Spectacular images, BlackWikkett. The IDAS LPS D1 has served me well for years but recently started using the Optolong L-enhance filter in my greater LP, more humid Florida skies compared to California. Are these under fairly dark skies?

Re: The Crab & California Nebulae with a hyperstar

Reprocessed as I added a few more hours of the California Nebula (NGC 1499) for a total of 6 hrs vs the 2 hrs I posted above. I think this looks a little better but have steered at it so long that I am not sure anymore. It would be nice to capture nebulae like this on nights with above average trans...

Re: The Crab & California Nebulae with a hyperstar

Thanks for the compliments. Both of these are 60s unguided stacks for 2 hrs. I am always fighting high humidity, resulting in below average transparency. Also, after moving to Florida 18 months ago, I think I have had maybe 6 weeks of great skies. Not good after spending a fortune on building an obs...
