Getting a time series tonight at 180 Sec in Rc, with a Planewave CDK-17. SNR is only about 22, binned 2x2, possibly during an eclipse/dip(?)
Should I shoot at 240 sec and get a slightly better SNR, or can the data be used at a little over 20?
Clear skies,

I was able to get one hour of time series on this star last night, 3-4h UTC July 10, and then clouds came in. I'm using a Celestron C9.25 with a V filter and 300 sec exposures, and I'm getting SNR of about 50. I didn't notice anything obvious during the period I captured.
I expect to have better conditions tonight, although I understand this is getting towards the end of the expected eclipse window.
Thanks,

It's really bad...
Here, in Quebec, the sky is covered by the smoke from the forest fires that come from Ontario.

Nex time!...
I uploaded about 2 hrs worth in V,I and Clear. Celestron C-14 Edge HD
I just uploaded 7 hours of data from last night, 2:30 - 9:30 UT (short summer nights). Is there the need for additional nights? If not, I plan to return to my regular targets tonight.
I didn't notice any dimmings in my data.

Does anyone know if we should continue time series on this one?
