This is my first photo-posting!  It is a 2 panel mosaic of the rho-Ophuichi Cloud Complex.  Between weather and equipment issues I thought I'd lost it for the year but managed to sneak in some time.  In the end, I got less than 4 hours per panel total when my goal was 10 hours so I'll probably add to it next year.

 

This is the first "real" photo from a remote observatory I'm setting up about 40 miles north of Lake Tahoe (21.4 w/ the moon and 21.7 without, except of course in the south where the light dome from Reno is just apparent).

 

Dates:         June & July 2020
Location:     Remote Observatory 50miles north of Lake Tahoe
OTA:            FSQ130 650mm at f/5
Camera:      PLI16803 monochrome at 1x1
Filters:         Chroma LRGB filters
Mount:          Paramount MX+ Unguided
Resolution:   2.86 asec/pxl drizzled to 1.45 asec/pxl
Software:      PixInsight   50 Darks, 50 Bias, 50 Flats
North is the left here

           Top Panel:                          Bot Panel:
Lum:     18x300s for 1:30:00    29x300s for 2:25:00
Red:      9x300s  for 0:45:00    10x300s for 0:50:00
Grn:     10x300s  for 0:45:00    13x300s for 1:05:00
Blu:       8x300s  for 0:40:00     13x300s for 1:05:00

 

Enjoy!
Thanks
Dennis

Sandy_Swede, sunnyday, Darren1969, snommisbor:

Thank you for the positive comments.  It was a lot of work, babying a balky dome remotely from 200 miles and dodging weather but the results were worth it!

 

snommisbor:  Best of luck this weekend.  It's a very large target.  This image is over >3* by > 6*.  Pick your favorite area and frame it well!
