I have been trying to troubleshoot excessive slew warnings (over 50%) when building models in APPM. From observing the Dec coordinate values in APPC I believe it is the Dec axis. Here is what I have d

Last time at a dark site no one was around, so there were no AP's, cell tethers, etc. Often there are MANY with all the apple-this, and asiair-that. So I was surprised to see the CP4 had opened an acc

Hey Astro-Nuts, We have another new video to share with you! If you’re using PHD2 for guiding with an AP encoder mount (Mach2GTO, 1100GTO-AE or 1600GTO-AE), this is for you. This tutorial covers basic

Hi, This one would be for Ray / Dale I guess. For an unknown reason tonight I get a "Invalid location for APPM settings file" when inserting the Dec Arc Model in the NINA advance sequencer (Astro-Phys

Is there a PDF version of the PEMPro Help File available ? I can print pages from the on-line version, but the printing is not very well formatted. Mike

This is what happens when the weather forecast says it is going to be breezy overnight: https://www.astrobin.com/full/c2dyh3/C/ The original plan was to image NGC 5033 and NGC 5005 last weekend. Both

That's really great! Which software did you use to follow the satellite? Rolando

Hey AP'ers! Since we have been clouded in here in WA for a long time, I was picking through some old data on an imaging laptop of mine and came across 1.5 hours or M42 data I took from a relatively da

Does anyone know what the length and thread of the following set screw is: https://ap-gto.groups.io/g/main/photo/274817/3424920?p=Created%2C%2C%2C20%2C2%2C0%2C0 It's part of the Y cable. I lost it yea

I'm trying to identify what counterweight shaft stop I need to purchase as a replacement. It is on an AP900GTO from 2005. The shaft is 1.875 in diameter but the stop that is supposed to fit it does no

Just wondering I have a 1100GTO mount that I purchased back in September 2014 I was thinking maybe its time to re grease the worm gear are there any instructions somewhere that I could follow? Also I

I was able to find only one amateur image of this galaxy, which is quite strange considering its size (4 arcminutes) and brightness (mag 10.6). I would have expected that its location in Virgo would h

I just upgraded the chip in the GTOCP3 from "J" version to "V2". Instructions say that I must reinitialize either via the hand controller or computer connection. How do I tell what version of firmware

Hi, I have two question /consideration that I'd like to be validated. In my former Paramount ME mount a sync issued by a sequencing software like NINA would result in a model corruption. I assume with

Im seeing a lot of flex and play in the Dec. axis under load. I noticed the dec axis is always very stiff, I figured this is how the new ones are. Tonight for the first time, after shining a flashligh

A local amateur took my image and looked it up for magnitudes. Faintest star recorded was 19.5, faintest galaxy recorded was 18.95

Wanted to see how faint I could go here at my light polluted industrial park. Local amateurs pointed out a tiny grouping of faint galaxies that they haven't been able to get much info on them or any d

This object was near the zenith at the time I took this image. Roland

I think that it's an aircraft, not a satellite. The reason is that there are at least 4 trails visible in the frame that are parallel to each other. There are the two corkscrew shaped ones, the bright

I have configured horizon and meridian limits for a scope combination. I changed the image train (now it is much longer), when running a pointing model using APPM, I think the scope hit the pier and I
