Michael, That is hilarious! Now I want to see you work on Wade’s analogy. :^) Clear Skies, Marj Christen Astro-Physics 11250 Forest Hills Road Machesney Park, IL 61115 Phone:

Hi David, I noticed in your video that your timing offset is set to 10 seconds. Make sure you set that back to 0 when you get out to try it (provided your computer time is accurate). Here is a video

Major cool Roland. I bet you could also pick up some of the big M31 Globulars with that scope too. I've visually seen them as decidedly non-stellar in our 11" F12 achromat. Give it a go. Jeff

Hi Astronuts, Just posted my final quickie image taken with the 12" F12.5 Mak-Cass. M31, familiar object, up close and personal. https://www.astrobin.com/hzazjs/ Rolando -- Roland

Here’s a time-lapse version.

As mentioned in another topic, SkyTrack now has continuous-tracking capability with compatible ASCOM mounts, including the Mach2. Here’s a YouTube video showing some indoor testing I did. It shows

Thanks for great explanation of the differences Roland. I have a 900 and also a 1100 (no encoders yet). More information now to make the decision to add encoders to the 1100.

>>>3600/266 yields 13arc seconds per hair. a 13 arcsec error would cause hair to ignite and telescope operators to take up pitch forks. These are tiny tiny movements. that "giant dec leap" seen in

This may be a better alternative guide scope setup. Two reasons. One is it's rock solid and other is it has longer 250mm focal length than your 165mm guide scope.

Howard, I love that analogy. And only because I ‘may have’ been dropped on my head as a child…..’ I decided to do a little experiment. I measured a human hair…yes I actually did. My hair

Hi Dale, Yes, with Ray's help it looks like things are sorted out and running as expected again. Thanks for posting your MF settings. Mine matched except for the use of "Use telescope side of pier"

I like to use this one: Take a dime and hold it out arm's length, noticing its diameter. Now imagine pushing the dime 2.5 miles away. The diameter of the dime at that distance is one

Hi Gang, One of the great new features in APCC v1.9.x is Dec Arc Tracking. There was some discussion when v. 1.9.x was released, but there were many other subjects for discussion as well. In the

The wiki page Dec Arc Tracking in APCChas been updatedby Howard Hedlund <howard@...>. Compare Revisions

@Nicolas, to clarify: The GA run shown here was done through the main scope, not the guide scope? So the guide scope connection is not the cause of these DEC jumps...? Of course, guide camera

>>>Remember we're talking widths of a human hair scale of movement, very small <<< I always liked this analogy: Hold your hand out at arm’s length and stretch out your fingers as far as you

>>>It is the standard finder bracket included with the Explore Scientific telescope. can you upload a pic? If it's what I think it is, that can be (and often is) a huge source of movement. Remember

I have the same problem, no matter what combination of settings I use, APCC always reaches its meridian limit a couple of minutes before SGP, causing the SGP session to abort. I had a similar issue
