UPDATE: The firmware appears to have been updated to fix this bug. See the note at the end of this post.

The other evening I was doing some imaging using my refractor on my iOptron GEM45 mount, and ran into a bit of a snag. I use N.I.N.A to manage my imaging runs, and I set up N.I.N.A and the iOptron ASCOM driver (iOptron Commander) together to handle the meridian flip needed during the imaging run. But while the meridian flip had worked just fine in previous imaging sessions, this time the meridian flip failed, and I had to manually intervene. But why?

Post-processing astro images is probably one of the most challenging parts of the astro imaging process. So I’m always on the lookout for tools that can help me improve my images. One tool I recently added to the toolbox is Denoise AI from Topaz Labs.

At the request of a user, I updated my ASCOM Driver for Digital Setting Circles to include a couple of the northern constellations–Ursa Minor and Draco. These constellations were added because the user had a limited view of the sky and needed more northerly stars on which to align. However, in general it is better to choose alignment stars that are not so far north (or south).

The download link for the driver installation file has been updated on the ASCOM Driver page.

Finally. I’d been waiting for weeks for an evening that would provide decent enough conditions for me to attempt my first imaging session with my new telescope, camera, and mount. Between clouds and smoke from forest fires, I’d been stymied for quite some time, but last Thursday evening finally presented clear skies and a little dark time before the moon rose so I could set everything up and try some long-exposure imaging of deep sky objects.

My first attempt at imaging M31, the Andromeda Galaxy.

The William Optics UniGuide 50mm guide scope

In my quest to put together a decent starter package for doing deep sky imaging, I purchased a William Optics UniGuide 50mm guide scope and a ZWO ASI290mm mini guide camera to use for guiding my main telescope during imaging. Both appear to be fine pieces of equipment, but when I did some bench testing I discovered that in order to bring images to focus in the ASI290mm mini guide camera, it had to be positioned in the guide scope such that it was just barely inserted. Some additional length in the guide scope would be a good thing.

Well, comet Neowise has come and (pretty-much) gone, but it put on an impressive display while it lasted. I managed to get out my camera one evening and take a few pictures, including this one:

Comet Neowise, taken July 20, 2020 from Woodland Park, CO (elevation 8400 ft). Taken using a Canon 250D DSLR with a Canon EF 50mm lens at f/1.8, 5s exposure at ISO 3200, modestly processed with Affinity Photo.

I’ve been running my NexStar 6SE scope in the field using an old 12V 7-Ah gel cell battery for awhile now, but it’s kinda heavy and has to sit on the ground, meaning I have to pay attention to not getting the power cord wrapped around the mount as I slew the telescope. I really wanted to find something that was light enough to attach to the arm of the mount itself but still had enough power in it to run the scope for at least an evening. Surfing some of the message boards, I found several reports of people using battery packs from TalentCell. The message board posts claimed up to several nights of observing with their battery packs. It sounded like I had found the answer.

Thanks to some help and testing from Pete Eschman, I’ve been able to restore support for Orion telescopes to my ASCOM Driver for Digital Setting Circles. Specifically, Orion Sky Wizard 2 and 3 and Orion Intelliscope platforms should now be working. Please let me know if you have problems using the driver with these platforms.

Orion itself gets no credit for this–they repeatedly ignored my requests for technical support on this issue, despite the fact that the ASCOM driver they published was a slightly-modified version of one of my earlier drivers.
