My focuser is taking a lot more effort than usual to move, even with the tensioner loose. It feels almost like there's some rubbing internally. I have a FocusLink focuser motor and it was jamming at

Hi Yves, Yes, that's the way it works, but we can change that in a future release. If you open the help file by clicking the "?" (help) button on that page, you can see the settings for each map

Hi Ray, Thank you for your advice. Regards Stephane

Thanks! cytan

The AP1100 is more accurate than the Mach1 due primarily to the larger gearwheel size. We have a number of them in stock and the test results on these are running around 3 arc sec P-P with PE off,

We are located 60 miles west of the Chicago suburbs, just a few miles south of the Wisconsin border. Normally the seeing around here is around .5 arc seconds RMS. You can tell the seeing by just

So if I'm going to move my finder guider to the focuser of one of my telescopes should it be the carbon fiber one or aluminum one? The carbon fiber version has the 3" FT version that can be focused

Hi Stephane, You always should enable it. The option allows the refraction component to be separately used without enabling the pointing terms, which by the way, are not polynomial corrections. In

Hi Lee, APCC Pro version now uses refined calculations, allows you to filter out bad points in the pointing model, and breaks out refraction from the pointing terms. There are also new graphs that

Hello Ray, Maybe this was already mentioned, but since the v1.7, I do not see any information on the help about the checkbox "refraction correction" I can see on pointing model tab above numbers of

If you mean an already loaded and active model, good question. If you mean saved model files being loaded and able to be executed for a new model it works fine. The bigger question in my view -- is

Hey Ray, Reading through the version history I see the following: APCC - Totally reworked the pointing model functionality for improved pointing and tracking rate correction. What's the significance

Can highly recommend the AP1100 CP4 mount. Excellent product. APCC Pro just had a rework done of the APPM pointing model too. Really excited to give this a go tomorrow. Will be testing unguided

P.S. After reading my previous posting I think sounded a little flippant. I'm sorry if I did. I'm asking because I'm trying to improve my guiding. And I'm actually looking at getting an AP1100.

Hi Rolando, Just out of curiosity where is your observatory? I live in Naperville, IL and the seeing is never that good to yield this type of numbers. The best rms that I've seen on my Mach1 is

By the way, I have graphs taken with the 17" on our 1600 mount, on a good night I am guiding at 0.1 arc sec RMS with that rig. That's not unusual. The pixel scale of that guider is 0.32 arc sec per

I made a mistake in the pixel scale, Typo. The pixel scale is 2.3 arc sec per pixel. Sorry about that. Rolando

He used a QSI683 WSG, so it was an off axis guider built into the camera.

Hi Rolando What guide camera and scope are you using for your guiding? 1.3 arcseconds/pixel is about a factor of 3 smaller than what I have (3.86 arcsec/pixel) which is QHY5-II and 170mm scope.
