A Great Night Under the Stars

Back in the real world, and at my other job, System Overlord of SBO (Sommers-Bausch Observatory, CU Boulder), we purchased two Paramount Tarus 500 mounts with Planewave 20" CDK Telescopes this winter.

Until recently, they had been running with a minimal TPoint model as I only had a few weeks for the whole setup process which included the removal of the DFM telescopes, and modifying our piers for the new telescopes. If you are interested in seeing that process I took a time lapse of the installation

Over the last week or so, we have been collimating and aligning the telescopes. I began by adjusting the polar alignment and after a few attempts, aligned both to within 1 arcmin of the celestial pole in altitude and azimuth. Then I ran a full 250 point automated pointing run.

The results are astounding.

The first telescope, Apollo, has a pointing model with an RMS of 5.33 arcsec.  After the first 50 points of the second telescope, Artemis, the RMS was about 3.2 arcsec, which blew me away. But I thought, well that's neat, but there is no way that is real. I proceeded to run another 200 points, and the RMS was...3.27 arcsec. I was astounded!  After that I took a few nice photos and was able to track 10 minutes, unguided, without a hint of trailing. I am really excited to see how long I can push the unguided imaging envelope.

The photos and TPoint graphs are below for your viewing pleasure.

Very impressive.  That's the lowest (best) RMS pointing I've ever encountered on any Paramount Robotic Telescope System.  Nice work!

Can you really see that many stars in the night sky?" The answer is, sadly no. Though you can see it quite clearly with your naked eye (if you are in an area with very little light pollution and no moon light)

So dull and UN-contaminated by some other light source, we saw falling stars, the thick band of the smooth way and the universal space station zooming past.

Apollo, has a pointing version with an RMS of five.33 arc sec. After the first 50 points of the second one telescope, Artemis, the RMS turned into about 3.2 arc sec, which blew me away.
