Hi Dean, APCC and APPM can also map data points with counterweight up! Thus some parts of the sky can have a different model depending on the pier side. To do this you need to setup Meridian Limits,

From my limited knowledge of SharpCap, it's not suitable for very long focal lengths. Michael

As I mentioned in my other post, it is best not to download a new version until it is released or you might run into unanticipated issues. Clear Skies, Marj Christen Astro-Physics, Inc 11250

Bryan and others, Sometimes, a user will report an issue to Ray. Ray will fix the issue and then provide the user with a build to verify that it works. There is no point in releasing that build

The test run worked fine. Now to execute under the stars. Another dumb question... When using the full sky model derived from the APPM mapping run, when should a meridian flip be executed? As I am

Sebastien The amount of drift, measured in arc-seconds per unit time, will depend only on the mount. How that drift appears in an image will be a function of the scope and camera. Bryn

Ray Thanks! Bryan

The Polemaster is designed to get you pretty close, but resolution limitations of the small focal length of its C-mount lens will naturally impart a limit to its accuracy. I would say that it alone is

I'm not into pixels, I'm more looking at allowable arc seconds. The skies some nights allow you to capture 3 arc sec FWHM, but on good nights you can get perhaps 1.5 arc sec FWHM. With a shorter scope

Bryan, Offhand I can't think of anything besides the version of .Net Framework that is different between PEMPro and APCC. Of course standard and pro APCC use the exact same routine and .Net Framework

Ray There are several of us that have made the same observation in this thread about the lack of notification. That reduces the likelihood of MS or AV being the cause. What info can we provide to

Aha! Very cool. I will definitely give it a trial run in the garage. Thanks Ray. -- Dean Jacobsen http://astrophoto.net/wp/ Image Gallery - http://astrophoto.net/wp/image-gallery/ Astrobin -

Dean, A few more tips: * If you want to see the order of the plate solves, enable the "Show Order" checkbox. You can animate the point order by clicking the "animate" button. This is just purely a

PEMPro and APCC use exactly the same mechanism which leads me to believe, at least in your case, either Windows firewall or your AV program is blocking APCC. -Ray Gralak Author of APCC (Astro-Physics

I won't always announce every build immediately. It depends on the criticality of the build and if I would like to get feedback first before announcing it. I may even skip announcing a version if it

Thanks for the pointers Ray. I will definitely use the horizon limits feature. -- Dean Jacobsen http://astrophoto.net/wp/ Image Gallery - http://astrophoto.net/wp/image-gallery/ Astrobin -

Hi Dean, > So, for the purpose of collecting measurement points, is there any need to set the Min. Altitude to anything less than > 45 degrees or maybe 40 degrees? No, there isn't. > With

Rolando, I'm not sure I'm getting this right. I'm probably missing something about the modeling part here... Please enlighten me. I thought the "amount of drift I'm willing to accept" was the amount

I'm reading the APCC/APPM manual and setting up the software for a trip out to the observatory next week where I will try to get pointing and tracking correction enabled on the Mach2 for the first

You can use this link to get it: http://www.apastrosoftware.com/apcc_download/APCC_Pro_Setup_1.8.3.1.exe I had to take a guess at it, but the similarity to the 1.8.2.1 version address worked. Jerome
