SJAA is pleased to announce they will be hosting their Annual Fall Swap Meet
Sunday October 29th at Houge Park, Bldg #1, from Noon to 3 pm.
Details will be updated and available here: www.sjaa.net/events/swap-meet/
Meetup also has an event posted:  www.meetup.com/SJ-Astronomy/events/239267951/
The current details are not completely accurate ... I am just trying to get the word out so folks (and clubs can put it on their calendars)
SJAA will only have 1 table worth of items and maybe a few scopes, so will be taking up very little room.

you can put a queen airbed and a couple chairs inside a shiftpod, with room to spare.

TAC Imaging / IC5146 (Cocoon Nebula) and B168
« Last post by jeffweiss9 on September 20, 2017, 10:30:06 PM »
An 8.8 hr LRGB image of the Cocoon Nebula in Cygnus and Bernard B168 that is wrapped around it and trails off to the West (right) in the image.
The Cocoon reflection/emission nebula appears to have more reflection than emission in this image using the new Photometric Color Calibration in PixInsight 1.8.5.  Link with more info at:
