160GB of free space. I don’t think that’s the problem but a good reminder to always check.

This morning I allowed Windows to run updates on one of my two imaging systems and it turns out that it updated Windows 10 to Feature version 22H2. Tonight, APCC become unstable and unresponsive, with

If I remember right that’s how Kendrick arranges the powerpoles on their batteries. If the two connectors are not glued together, they can be rearranged but I wouldn’t count on it. Powerwerkx is a goo

I believe Rogelio Bernal Andreo was one of the first (if not the first) to image the Ha clouds of Andromeda. Luca

That’s so cool! Nice work, Jim. Luca

That's a really beautiful field of clusters, Dean, and perfectly executed. Can I ask what data acquisition software you use? Thanks for sharing! Luca

The Rose is such a beautiful galaxy! Nicely done, Dan. Best, Luca

Last night while imaging unattended my Mach2GTO reported a motor stall condition, which caused the imaging run to fail. Nothing has changed in my imaging system in months (observatory mounted FSQ106 o

Dan, The link worked. The Ha structures throughout M33 are so intricate and detailed. If you are interested, there is a great paper by a Marseille astronomy team on a Ha survey of M33 (https://article

The resolution of the FSQ106 with the ASI6200 sensor is 1.43 arc-sec/pixel, quite modest. If I were to point the 10in f4 newtonian on Abell 79 I bet I could get the inside jagged edge of the oxygen ri

Mikey, Karen, and Terry, thank you for the kind words! Emilio, yes PN G101.5-00.6 is the 1 arc-min blue bipolar object above and to the left of the open cluster NGC 7226. See below two close-ups of th

It has been too long since I processed completely an image. Finally I managed to convince myself to sit down at the computer and process a new dataset. In the meantime, the Mach 2 and the AP1100 have

I have used the Losmandy Folding HD tripod and it offers excellent stability for the AP1100. Luca

Great work, Bill. I just opened the full size image in Astrobin and it’s truly a beautiful field! Luca

Roland, Can you please comment on what parameters you use for optimization of the backfocus distance from the flattener or TCC? Is it nulling curvature over a specified field or is it a trade-off betw

You can source XT60 to Powerpole pigtails for cheap. That way you can leave the original power cable that comes with the UPB v2 alone. Luca

Nice work, Bill! M106 is such a beautiful galaxy and the colors in your image are gorgeous. Maybe that’s what you refer to in your original post, but some of the stars appear to have a slightly asymme

Chris, I am West of you in the Capital District and image under similar temperatures. Given the relatively small difference in cost, I opted to go for the extended temperature encoders. I have never h

Roger, I image with a TS ONTC 10in f4 on a AP1100 non-AE and the mount can drive the OTA with seeing-limited performance even under windy conditions (30-40 mph gusts, mount inside an observatory). I s

Andrew, As Brian already pointed out, there is no need to manually change Minutes past Meridian to Flip in SGP if you check the APCC checkbox Send Limits to SGP. I do not check the Wait for Meridian b
