sv605 ir cut

Svbony 605cc doesn't have a uv-ir cut filter so...

cc and ff spacings therefore need an extra 1mm sensor distancing from the body of the optics.

e.g. with the q150

1. without filter:
17.5 + 30 + 6 = 53.5mm

2. with filter
17.5 + 30 + 7 = 54.5mm

Most easily achieved using the final m48 to m42 step down adapter, 6mm or 7mm.

veTEC test

First all night session since August. A pleasant surprise. All OK with the veTEC, the only problem being forgetting to tighten the DEC clutch after balancing, so the meridian flip just, erm, wasn't. Fortunately nature called at around 04:00 and I reset the mount and restarted the session.

veTEC571 back from Germany

Repair of the -loose- power socket made it worse. I assume it couldn't be fixed as Omegon sent a new camera. Why that took six weeks...? No idea.

A rough estimate suggested connecting and disconnecting cables to the camera ~500 times over the past year.

Suggestion as shown. Connect to the extension cables rather than the camera hardware.

Tested on both a galaxy and a cluster.

 Still no astro camera, but the old 450d is doing great. This time, an all nighter. It survived.
