As long as your mirror doesn't flop, I believe 10 minutes will work ok. If you have any random flexure in the optical train, it may not work. Rolando

Hi, Can’t find anything online about it. Do you have a link? Tony

Hey Tony, If you want to go unguided, try ATrack, get in touch with Craig Young on this forum for details. It works a treat! Doesn't use a guidescope or guider, easy as pie and VERY accurate! Steve

Jian, There are huge numbers in the boxes on your screen shot. Your PNT file looks bad. As I said, attach the PNT file in case it is different than what's in your zip file. When I load your

Hi Ray, It is very easy to recreate the lockup problem. 1. Start APCC pro, connect to Mount, connect to ASCOM 2. Use AP V2 driver to slew the telescope. 3. I can see the APCC pro locked up after a

Hi, I've been putting together my imaging train for my C11 and have hit a snag. The QHYOAG will be hitting the back of the LiteCrawler using the backfocus of the 146mm. I can't see anyway around this

Jian, There were two PNT files in your zip file. The first has only 2 points, but the other has 30 points, and loads fine in APCC. I slewed around parked, unparked, but I could not get APCC to

Jiang, Can you attach the PNT file that hangs APCC to a message here? It should be easy to figure out if I have that file. -Ray Gralak Author of APCC (Astro-Physics Command Center):

Jiang, Since I posted last have you followed any on my settings? Incorrect. The setting simply shows what plate solve coordinates will be stored in the PNT file. Here's what the help says: Precess

Hi Ray, I had successfully run two small-map twice when I unchecked "Precess J2000 to JNow", and consistently failed (only first two points solved) when it was checked. It seems to me that this

Hi Ron, A. Call the office for a grease kit. It is not on the website. B. Your Mach1 has the latest gearbox, which is not the instructions that are posted on our website for gearbox removal. below are

I forgot to answer this. Probably what happened is that you finally got a good plate solve, thus the others solved. The previous solves failed because of one bad solve which skewed the coordinates.

Jian, Okay, make sure you follow the setup directions in APCC's help file. SGPro has two different sets of plate solve parameters. One for internal SGPro use, and one for external applications. If

AP says they want to verify that you (and your mount) are in their user database before they sell the grease kit. Cost is $42.50, call or email them to order. Instructions are included, plus you

Hi Ray, Polar Alignment is very good done with SharpCap and PHD2 Drift alignment. I used AP ASCOM driver for imaging before I went to sleep in the past 2 nights and got PHD2 RMS total about 0.5 or

Call Astro Physics to order the grease kit. Thanks, Charles Sent from mobile device.

A link to order one? info price? it includes instructions? SEARCH did not reveal anything under grease? But displayed a LOT OF NON GREASE items? How do I remove the RA gearbox? manual shows 2

Wow… the first solve was off by 825 arc-minutes? That doesn’t look good at all. Are you sure you are polar aligned? What type of telescope are you using? -Ray -Ray Gralak Author
