Antennae

Only got 17 subs on this--took 36, but something went wrong about halfway through and PHD2 crashed so the rest were garbage.

Taken last night, so near full moon, and stretched to hell... but I'm just happy to be imaging again--it's been over six months now.

Plan to get a lot more data on this one and may even end up throwing out these subs, but for now it's just great to be imaging!

Considering the difficulties, you did well Lee.
Dew on the guidescope will cause PHD to crash. Was this your problem?

That's extremely good for full moon!

Thanks Robert :-)

Last night was actually one of the few nights where dew hasn't been an issue. I was using my dew heater for the first time, but when I finished up there was no dew on anything so I actually had no need to be running it.

When I went back out to the scope to pack up, PHD2 showed a reasonably good graph, 0.6" RMS in total (about as good as I ever get) as far back as it went, perfect guide star, but it was no longer capturing images or guiding.

I had heard a USB connection dropping in and out earlier in the night, but everything seemed to be working so I let it go. I thought it might have been the filter wheel at the time.

My guess now is that the guide cam, or mount was dropping in and out... I was using the built-in USB hub in the Trius 674 for the first time so maybe one of them doesn't play nicely. I'll experiment more soon and figure out what it was.



Thanks Kevin! :-) Need to figure out optimal exposure time for this new setup and get a decent amount of time under a new moon to do this justice.
