Dominique, Don’t want to scare anybody about this problem – but I would be VERY careful – with using a hair dryer on your expensive AP Keypad. If it helps momentarily by cooking the

Wow, Jian. That’s a really pleasing image. Congratulations! Karen C AP

Hi, It may only be part postponed,but if they were oily structures stuck on contacts and preventing the activation of the button, one could think that a dose of heat could thin the thing. So with the

Someone used the cool OnStep project to convert an AP400 - might give you some ideas: https://onstep.groups.io/g/main/topic/onstep_on_astro_physics_ap400/26511793 Michael Fulbright

Stepper motors are pretty easy to find and not expensive.

AP-Support: As an after thought about Keypad’s buttons eventually becoming too oily and losing their circuit board pad contact, may I suggest that AP Tech Support, with their usual excellent

You would probably have to replace the motors. Frank

Hi Joe, Thank you for the link to the related topic, actually the problem could be of this nature, since since 2011 I used this keypad in a common way and it has, depending on the period, lived

Thank you for the tips Greg. -- Dean Jacobsen http://astrophoto.net/wp/ Image Gallery - http://astrophoto.net/wp/image-gallery/ Astrobin - https://www.astrobin.com/users/deanjacobsen/

Hi Dominique, Don’t worry. No need to send your Keypad to AP for repair. Fixing buttons on ANY “rubber membrane” keypad (TV Remote, cordless Phone, AP Keypad, etc.), is easy, if you are

Since the 800 apparently uses stepper motors, it seems like it would be possible to adapt it to a recent controller, like the GT4. Has anyone ever done that?

Greg, Thanks for the information. You've highlighted a number of important parameters to double check in SGPro and APPM setups. I need to look through the program profiles again to make sure

Greg thanks, A veritable lecture in an email that is a real keeper!! -- TJF MOBILE

Dean and Joe, I normally watch this forum and learn from the experienced astronomers and imagers, but wanted to pass on a few thoughts about my developing experience with plate solving and APPM.

Thanks Marj I'll call on Monday then. Thanks for getting back to me quickly. Carl

The same folder as the logs. BTW, when APPM is collecting data if the image has been saved you can double-click the failed line in APPM and the FITS image will be opened in the default FITS viewer on

I'm using 8 second exposures at ISO 6400. Nominally not all that different from your exposure time although the high ISO when starting the mapping run early in the evening may be washing out the

OK, thanks. The setting to save the failed solves is already checked. I'll try solving those independently and see if there's a problem with them. Where are they saved in the file structure?

Hi AP, The keypad (3388GTO) of my Mach1 dating a little (2011) I took advantage of the command of my Mach2 to take a battery to replace the original one. Everything went well and upon reignition I

i use SGP + Pinpoint for plate solve with exposure time of 5 seconds bin 1 (FLI proline 16803 camera). I got maybe 5 solve failures in a 400 point model and it took about 3 hours. not sure how that
