Comedy of errors at the first dark site for the new scope. The club had its monthly high star party on the first and I brought my new setup. I’d never been to this site so the first thing I do wrong is set the TriPier up so far off I could not polar align. The scope is a Stellarvue 130T with a Access 80mm piggybacked on a CEM60 not something to just slide over into alignment and still be level. I’m not sure how I got it so far off…maybe a piece of magnetic metal near the compass.
I did a little visual for an hour thinking I won’t image tonight, checked a few views through some of the big Dob’s brought up an then the itch to image got too overwhelming at about 12:30am.
So I pulled the setup down (in the dark), corrected the pier alignment… leveled and remounted the CEM60 and scopes. Polemastered it (gotta love that little toy), focused and sampled a couple of fast images of M51 and hit PHD and started imaging...
PHD would not settle and lock in…
An hour later I gave up on PHD and guiding and set the imaging for 60 sec. at a ISO of 1600 so I could capture unguided. Like I said, gotta love PoleMaster. I got about 100 images before the dawn light started. Lost 25 of those to spongy ground and 5 to planes , satellites ect.
Did my darks and bias but only got ten flats because the laptop battery died and I didn’t bring the backup.
(Later realized I had not plugged the guider into a powered port that was why the guider and PHD were not working . So stupid, I should have figured that out.)
All and all …not a bad night….
