I use APT for image capture. Here is the release email customers have received:
APT 3.80 arrived! It brings the highly requested native support for ZWO cameras as well as support for Pegasus Astro and ArteSky flat panels, support for more Canon models, support for the latest CR3 and NEF raw files, GoTo++ improvements, mosaics import from HNSKY or CdC and more.
Update your APT and be ready for the New Moon 🙂
The usual list of the changes is available here:

In July-October I had obtained a new refractor from Adorama camera out of New York for around $870. It has been decades since I possessed a good refractor so I could put the larger (and heavier) Schmidt Newtonian on the shelf for a while. The SN was very sensitive to collimation issues and I was tired of dealing with it. This refractor is an Explore Scientific AR152 6″ doublet. These are hard to find – they are selling out everywhere. I also ordered a new autoguider from Orion: Orion StarShoot AutoGuider Pro & 30mm Ultra Mini Guide and I am testing it out. Added a Rigelsys Explore Scientific Focus Motor and nFOCUS. In addition, I have purchased a field flattener. I am currently shooting with my old Cannon Rebel T3: the ZWO ASI178MC works well, and I do image with that intermittently, but I have always had better success with DSLR.
Images posting soon – as soon as I learn Nebulosity image processing…
I had attended the Black Forest star party over the weekend of Sept 27th 2019. Many speakers were there, including Trevor Jones from AstroBackyard. Skies were fair and seeing got better into early Saturday morning. Here are some pics from the event.
I am attending the annual Black Forest star party at Cherry Springs state park in September 27-29 2019. I am very excited to attend this national dark site and do some astrophotography and simple visual observing with the public.
About the event: “The Black Forest Star Party (BFSP) is an annual dark-sky amateur astronomy observing event hosted by the Central Pennsylvania Observers (CPO). Held every year since 1999, the BFSP generally spans a weekend in the late summer or early fall in Cherry Springs State Park in Potter County, Pennsylvania.
Cherry Springs State Park is one of the darkest sites in the state of Pennsylvania and has been designated as Pennsylvania’s first Dark Sky Park by the PA Department of Conservation and Natural Resources (DCNR)…” (Black Forest 2019).
Here is a list of this years speakers:

BE ALERT FOR PERSEID FIREBALLS: Earth is entering a stream of debris from giant Comet Swift-Tuttle, source of the annual Perseid meteor shower. Forecasters say the shower won’t peak until Aug. 12-13, but already NASA cameras are catching Perseid fireballs streaking over the USA. The Perseids produce more fireballs than any other annual shower–largely due to the size of the parent comet–so your chances of seeing one are good.

M3 10 second exposure, Zhumell urban sky filter. This filter increases the contrast of deep-sky objects like emission nebulae and darkens the background sky by blocking mercury vapor light transmissions and enhancing transmission in the hydrogen beta, doubly ionized oxygen and hydrogen alpha regions of the spectrum. This filter, I have found, is no longer in production. Next filter to purchase is the Optolong L-eNhance filter. Or, the Optolong CLS filter at a lower price does basically the same thing. Image cleaned up with Gimp.
So far, I do like the DSLR images more, but this is first light with this small ZWO ASI 178 CMOS camera: the first CMOS camera I have owned. It will take getting used to. I believe this image is a .1000/sec capture in APT with the Meade LXD75 sn-10″ Schmidt Newtonian. Some atmospheric distortion exists.
