The trailing appears up and down generally in a N-S direction which I think corresponds to Declination. I stopped guiding and tightened everything down - especially the Dec and RA lockdown finger screws. The five minute test was completely fine.
So, I just took 9 fifteen minute subs of the Angelfish in H-alpha. The more I think about it, the more I think that it's flex in the system - specifically in the extremely longish refractor assembly which required a tube extension to get the autoguider to focus.

PLUS the scope slipped down from its rings. The darn rotator on the collar wasn't locked down and the telescope turned for the 20 min exposure. Tried to test the Tak by doing a 20min exposure, but just got a bizarre star trailing pic. Later.] >sigh< Another failed night of imaging. I don't believe it, but I need to verify it tonight. It could be that the system only works with some minimum weight like 15 lbs. I collected a bunch of data with the Tak102 at 15 min. Still have lines corresponding with R.A. Just trying a different part of the sky and more time. I'm collecting 30 min shots of the Spaghetti Nebula. Tired of gathering bad data, I also went to the Pyramid 13.8volt power supply wondering if the cold 10 degree temps were crippling the voltage from the Optima battery. The lines are spiky and my total RMS is around 1.8" which is on the crappy side of "okay". I also tightened the DEC and RA Gear mesh according to AP's instructions and the guiding is worse by a long shot (went from. Maybe theĮlectronics are getting too cold? DUMB IDEA. Used a different camera dovetail which was twice as heavy.ĥ) Cover the connection of the USB-Serial module w/hand warmers. Switched Camera and Scope poistions.Ĥ) ADD more weight on top by adding maybe another camera.
DONEģ) MOVE both the camera and guidescope to one side. 1) Disassemble the dual-saddle and tighten everything down.
