Observing Intents / Re: Observing Tuesday NIght?

I'm planning to also observe on Tuesday night -- either at Lake Sonoma (if the north bay forecast improves a bit) or else I'll head south to Fremont Peak or Deep Sky Ranch.

I would describe the entire Shingletown experience as "unforgetable".  I do think its a great photo.

I recognize that air strip. We had fun our one time there, in '03. I got way into the Coma Cluster. Always regarded it as a great blessing that Liam and I missed the year with the Clamper chili.

I plan to observe at Lake Sonoma/Lone Rock Parking Lot on Tuesday evening.  At least one observing buddy plans to join me.  The more the merrier, so come on out.

Going to Fremont Peak after all since the latest forecast shows the RH% considerably lower.  I'll be at the FPOA observatory offering a great S. horizon view into Puppis. I want to observe and sketch three planetaries in Puppis before that constellation is no longer visible by April new Moon.

I was thinking about doing something relatively short Tuesday night.  Depending on others' intents I might be interested in joining or I may go solo elsewhere so as not to disrupt things with an early departure.

The weather forecast looks good for Tuesday night at our observing sites.  It’s New Moon on Tuesday!  The Moon sets too late for Friday and the weekend observing.  Anyone interested in getting out to observe Tuesday night?

fyi, I sold this scope a few months back back to a fellow SCAC member to use as a grab-n-go SCT.

hmmm, said coulter has a 65mm (minor axis) secondary, so rough calculations suggest that with a 12" OD tube, plus focuser minimum height plus the 44mm flange distance of a EOS DSLR, I'd only get a 16mm diameter image circle before the image starts to darken significantly.    not good enough for an APS-C DSLR!! (which has a 28mm or so image circle)
