Thanks all for the additional feedback. I'll see how far I can go next time I put the hyperstar on. I have excellent polar alignment in my permanent observatory and other than sky conditions, I

Thanks, Joe. I have excellent polar alignment in my permanent observatory. I'll give it a go and see how far I can push the exposure time.

Curtis, Loosen the clutches; tell the mount to go to Park 3; wait until the motors stop running; put the mount in Park 3 with your hands and tighten the clutches. You’ll be fine. PS.

Date and time in the keypad are correct.

mike do you have the absolute encoders on that mount? and just curious if you're using APPC/APPM on that unguided Brian -- Brian Brian Valente portfolio brianvalentephotography.com

I can do 5 minutes unguidedwith my 1600GTO and Planewave 17 at 2935mm fl and .63"/pixel. Permanentsetup, very good drift polar alignment. Depends on other factors than themount. Mike J. Shade:

I usually do 90 seconds with my C14 Hyperstar & 1100 unguided for narrowband if it's a particularly faint DSO then 120 seconds. But there will be a few subs discarded usually due to mirror flop. I

Thanks for the comments, Bob Denny pointed me to the settings and the lengthy help in ACP but the bottom line is there is an flip ACP setting under telescope to set a fudge factor of say 40 minutes,

Bruce, I always shot my RASA unguided on my 1100. That’s basically what you’re hyperstar is. You’re probably only shooting 60-90 second images with that. I just aligned with my RAPAS and

ok- thanks for your input

Hi guys! Don’t want to be too much of a nag, but any news on Mach2 shipment? The website still says shipping in January 2020 and, well, this is the last day of January. I have really been hoping to

To many factors to consider. FL, alignment, seeing, all play a part in just how long you can go. I can confirm that a few years ago using my 140 f/7 and an ST-10 on a 900 mount, I could get 5-6

I can go up to almost 60' without guiding. Is it possible to get the mount to go up to 2 minutes unguided? If yes, I am assuming it would be by getting the PE down as best as possible given all

Turn PEC off in the driver, do not guide, and disable any other such influencer of mount movement such as tracking correction. When you're analyzing for a new curve, you need to have the hardware to

Ray et al I can't find any reference on this question in the Help files, but could have missed it. If I am acquiring data for a new curve in PEMPro, do I DISABLE Tracking Correction in APPC Pro?

Hi Curtis, Did your keypad time and daylight settings are ok? BTW, keypad firmware version 4.19.3 includes the Park 4 position. Best regards, Yves

I guess I need a refresher on Park 1. My CCD camera has died (herringbone pattern in all images). I decided to use my TEC 140/Mach1GTO for visual observing while I await resolution of my camera

Hi Marj, Thank you for replying . Ok it will only come with a (gtocp4)box . Thanks Regards Suresh

ACP will control the flip,screwing around in another program is not going to do anything as Ray hasoffered. I also run ACP and it will anticipate a "safety zone" for aGEM, based on altitude and image

Hi Jerry, No, ACP will probably not reliably work if you try that. Please read the earlier posts be Yves. -Ray Gralak Author of APCC (Astro-Physics Command Center):
