Robotic Telescope Editing Contest

Want to put your image editing skills to the test? Now you can, with the RASC Robotic Telescope image editing contest.

In collaboration with SkyNews, each month the RASC Robotic Telescope team will release the data for an image for the public to edit. Judges from the team will pick a winner out of those submitted. Click here to learn more: https://skynews.ca/introducing-the-rasc-robotic-telescope-editing-contest/

Deep Sky Images from an Edmonton RASCal

Edmonton RASCal Abdur Anwar Captured the Cacoon and Bubble on August 9th

Abdur writes: Finally had a clear night last week and I spent most of my imaging time on the Cacoon Nebula (IC 5146) and the Bubble nebula. I got about 2 hours of data on the Cacoon and about 1.5 hours on the Bubble nebula using an ASI1600mm and an 8″ reflector. Really happy with how they turned out 🙂

Equipment and capture details for each target in order:
ASI1600MM Pro
ZWO LRGBHa filters
Ha: 12 mins (Cacoon) / 27 mins (Bubble nebula)
RGB: 20 mins each / 10 mins each
L: 60mins / 30 mins
Scope: 8″ f3.9 reflector
Mount: EQ6R Pro

Cacoon Nebula (IC 5146)
The Bubble Nebula NGC 7635 …Caldwell 11

Rho Ophiuchi Cloud Complex by Dan Posey

Bill Weir encouraged Dan Posey to visit the Pearson Site. The result was at stunning photo at this link: https://rascvic.zenfolio.com/posey/head1949f#hebe220b7 This file is large but the click is worth it! Check it out.

Dan writes: “Thanks to Bill kindly hosting last night, as the conditions at Pearson provided that opportunity I have been waiting for. The result isn’t perfect but that just means I’ll need to revisit in the future; I know where I need to be to take a longer stab at this target next year. This is 48.5 minutes (97x30s) using my Sigma 105 at f1.4 and my Canon Ra at iso 640.”

A Lunar Album from Mike Nash

Victoria RASCal Mike Nash captured images of the Moon 9 nights in a row. Watch the features change as the terminator crawls across the surface.

Title: Peering Into the Darkness with the JCMT: Witnessing the Birth of Stars

The birth of stars remains shrouded in mystery. Stars form inside thick puddles of gas and dust located primarily along the spiral arms of the Galaxy. Astronomers use infrared and radio telescopes to peer into and through these murky puddles to witness the birth of stars. For over 25 years the JCMT has been leading investigations to uncover the formation of stars in the Galaxy. In collaboration with the Spitzer Space Telescope, the Herschel Space Observatory, and the ALMA Observatory in Chile, the JCMT has transformed our understanding of stellar birth. Join me on an adventure to uncover nearby stellar nurseries.
