Wow, no idea what happened... I've had my Ap1100 for about 2 months now. I was imaging tonight and everything was great. I did about 3 hours, tracking was 0.31 arcsec RMS. All of a sudden the guide st

Ray, in another topic you mentioned: AP V2 driver 5.40.01: https://www.gralak.com/apdriver/AstroPhysics_V2_Setup_5.40.01.exe APCC Pro 1.9.3.1 https://www.apastrosoftware.com/apcc_download/APCC_Pro_Set

Hi, I am using ACP and Expert Scheduler. Normally after a night's run everything shuts down including APCC but I have never been able to get the ASCOM driver to reliably shut down. If it is alive APCC

Newbie comet photography questions. Do people create custom tracking rates for comets in APCC, or just track at sidereal rate generally, or use some other software? Thanks Bob

Hi Not really a GTO question, but your CCDT67 CCD Telecompressor was recommended as a Flattener for use with my Astro-tech RC 14” truss. I was wondering if anyone could comment on the use of the flatt

Hi all, Still in my learning phase using Ascom driver, when i use goto, the mount stops with error message ; Fault Triggered: MotorStall Any ideas ? Best, Alain Prette

Sometime after 3AM this plastic part moved. What's its function? Where is it supposed to be? Is there a way to convince it to stay put?

Folks, I have observed slight ‘play’ in the R.A. axis of Mach 2 Mount. Observations: 1. When a slight force is applied to the counter weight shaft or telescope with the clutches locked, there is ‘play

I received my compass upgrade kit for my Mach 2. The kit came with steel post, plastic gasket and gasket maker glue? Does anybody have directions on how to install this? Once installed how do you use

Note for Ray :-) Primalucelab has added a local web server to access Eagle controls and data, such as turning ports on or off, etc. The command to get GPS coordinates is: http://localhost:1380/getgps

My AP-1100 (August 2021, no encoders) shows, most of the time, slightly worse guiding in Dec than in RA. A typical example (one 300sec frame) looks like this: The blue curve is the RA and the red one

Ray, my first chance to try and connect my Mach2 to the mount was yesterday with disastrous results. On start up, I get a message "Invalid response from the mount. Firmware version V or later is requi

Hey Astronuts, How cool is this?!? Another Bravo to the fine folks at NASA and Johns Hopkins University Applied Physics Laboratory on their successes with the Parker Solar Probe! Check out the videos

Hello fellow Astronuts,Can you stand another Pleiades image? 100x60 second stack: https://www.astrobin.com/2a2esk/0/ I had a clear and very cold night on Monday, so took the opportunity to do some sco

I'm trying to debug a mystery crash that may have been power . I have separate power to the mount and to the computer. I know the computer restarted, I would like to know if the mount power cycled als

Not sure if this is a problem or not, but couldn't find mention of it anywhere so I thought I'd ask. When I insert the RAPAS into the mounting bracket on my Mach2, it doesn't slide all the way in. Com

I got this image last time I was out at my observatory Paducah, TX. I got the same reflection that was on my last shot of M78. I moved my filter placement because of the last time so not sure how to a

I uploaded a full frame test image that I took back in November using a customer's TCC that he claimed had bad star images. This image used the ZWO 6200C color camera. The image has some gradients cau

I seem to have fat-fingered the PEM setting in APCC Pro last night and I was wondering whether the PEM change gets written to the APCC log file. This would help me separate causes of tracking problems

Hi Ray, My observatory-based AP1600 CP4 lost its location last night after a few days of no activity due to clouds. It’s been tracking great using a 300+ point APPM model on 180 second unguided exposu
