Roland, does that include the older mounts like the 900/1200 and Mach 1? Jeff

For Astro-Physics mounts best practice is to balance. Our mounts have spring loaded worms, so do not need to be unbalanced. Rolando

Hi I have read that best practice is to have the balance heavier on the counterweight side when imaging to the east. Ok, makes sense. However what happens at Meridian flip? It's now completely

Really nice Roland and one of my favorites too, in fact, the very first deep sky object I saw with my first telescope, a Sears 2" F11 achromat. I've noticed that you and other skilled imagers manage

Just got around to processing my winter project. Images were taken back in February on one bitter cold clear night at our northern Illinois observatory. This much-photographed object is still one of

Hello, Just a reminder for those who procrastinated – the deadline for completing the form is noon, central daylight savings time – TODAY! Yes, I know the last week passed very quickly.

Thank you for taking a look, Ray. Let me know if there is any data I can provide that would be helpful. Luca

Hi Luca, For some reason, APCC thinks the Home operation failed. The slew to Home completed the move, but there was no attempt by APCC to sync the mount. I'm not sure why (yet). -Ray

Yes, APCC has a Home function for non-encoder mounts, but to work homing requires that the scope not be moved by loosening the clutches. This should be the case at a remote site. It works by saving

One of the happiest days of my life was the day I sold my 10” x 42” ATS portable pier that I used for my 1200. That was a heavy beast and I had to lift it up on the tailgate of my F350 4x4 and

There’s a 10”x42” ATS pier currently listed on Astromart under Mounts-Equatorial. Located in Texas. Chip

Hey Linwood, I’ve had my AP100 non AE since March of 2020, before the SHTF! I have never been sorry for the purchase, can’t believe how wonderful a “premium” mount really is. I got lucky

The last few nights I have been experiencing runaway behavior with the Mach2 when the imaging sequence starts in SGP. The target is in Cygnus, in the Eastern sky and when SGP issues the first slew the

Hi Michael, The Keypad uses a special battery. You can contact Astro-Physics and they can sell you the correct battery for your Keypad. Fred -- Fred Keller Gold Cr

Better balance is good. Generally I try to place the filter wheel vertical with the scope in the Park3 position. That would produce the best balance. That assumes that the camera rotation can be

I rotated the guide camera 180 Degrees and the balance is much better. I wouldn't say I am obsessing about the RA balance, but I am trying to avoid any situations where the RA axis is heavier on the

According to HKursh: >> The 'HOME' button does not exist on a mount without AE. It is on the AE tab of APCC pro. According to astro-physics.com ( https://www.astro-physics.com/apcc -

But why are you obsessing about perfect balance in RA? I already indicated that it's not that important in RA because there is no static friction to overcome. Roland

Very simple. It's caused by your filter wheel being sideways. You would need to add a small counterweight on the other side, opposite to the filter wheel, in order to achieve proper Dec

Hi George & Roland Here are a couple pictures of my NP101is imaging train in Park 3. If I disengage the RA gearbox from Park 3 the scope will tip over to the east and oscillate back and forth a couple
