So I guess I have tested my abbreviated all sky model at pixel scales of 2.47 to 1.48 arc seconds per pixel and every subexposure has looked good. -- Dean Jacobsen http://astrophoto.net/wp/ Image

Beautiful instrument Jim! I agree, just something about viewing the universe with your eyes. tony

That makes sense, thanks. I literally learn something new every day by reading posts here. -- Dean Jacobsen http://astrophoto.net/wp/ Image Gallery - http://astrophoto.net/wp/image-gallery/ Astrobin

It has less to do with focal length than pixel scale. For instance, a 500mm focal length and 3micron pixel will have exactly the same resolution as a 1500mm focal length and a 9 micron pixel. Rolando

Well, I have imaged the Moon and Planets with mine (earlier version) and could not be happier with its performance. I may be part of the end of the era of visual observations and am happy to say I

WOW! Simply beautiful! More rare than hens teeth... 😎 Pete

Craig, I have been setting up APPM to take measurements on three declination lines that more or less bracket my intended target [I say "more or less" because the middle line is close to but not

Thank you for making these superb instruments. I am very please you made another group as I got one earlier this year. Seeing the one your brought to Astrofest many years ago prompted me to put my

Hi Astronuts, Today I finished the last of the 10" F14.5 Maks, which will go to whoever is on our list. This is the last of my hand figured Maks that I plan to make of this size and focal length in

Mach1GTO, CP3 controller, Starlight Xpress Superstar guider, Baader Vario-Finder guide scope, MaxIm DL 6.21. The computer is connected to the mount's serial port with a Keyspan adapter. Has anybody

I will give that a try on my next clear night. First, I will create a new model with two DEC arcs, with the target DEC arc sitting between the two sample arcs. That way the model straddles equally

Ok. Rolando

Hi Leo, APCC already integrates with SGPro to set meridian limits and flip points. You can set this up on the Meridian Limits tab. Take a look at the Meridian Limits section of the help file if

Having a low voltage halt result in a solid yellow light and a limits halt result in a blinking yellow light and a hardware stall resulting in a S.O.S. blinking light (for examples) would be a nice

Excellent! Good to know this. -- Dean Jacobsen http://astrophoto.net/wp/ Image Gallery - http://astrophoto.net/wp/image-gallery/ Astrobin - https://www.astrobin.com/users/deanjacobsen/

The problem is with which data points are in a model. Some of the terms have factors that vary directly or indirectly by declination. After subtracting refraction, some values used to calculate

I recently contacted SGP forum after dealing with aftermath of pier collision after failure to perform auto flip. I think I've sorted out most of the things and I have now solution in hand, but I

Rolando, Thank you for answering my concerns. Your explanation makes sense to me now. Leo

I explained that in a previous e-mail. Did it not come thru? Rolando

Dale, I've mentioned it in description of the problem that there was no external mechanical force on the mount - it stopped at homing limit as was set in APCC. The mount was well balanced in both Ra
