Impressive Images of Mars from Edmonton RASCal Abdur Anwar
Abdur Anwar dusted off his old Celestron 8 inch Schmidt Cassegrain Telescope and put it to good use using a lucky imaging technique to capture some amazing images of Mars. On August 25th Abdur experimented with the program WinJupos which can remove the blurring effect caused by rotation. Check out the before and after images below.
Speaking of Mars check out this 4K video
The video in this link displays a collection of high resolution images taken on a number of Martian space missions. It is 12 minutes well spent.
Hawaiian Nights: A Personal Journey from Vancouver Island to Maunakea, with Cam Wipper
Don’t miss this interesting Zoom presentation at 4:00 PM PDT on Friday August 28th. Growing up in Nanaimo, Cam never imagined he would spend nearly a decade living in Hawai’i and working on Maunakea, the best place on Earth for astronomical observations.
In his talk, Cam will tell the story of how he found himself on Maunakea, from his days as a student at Vancouver Island University, to his first night up on the summit of Maunakea, nearly 14.000 feet (4200m) above sea level. This will include a brief history of astronomy in Hawaii, as well as an exploration of how a modern astronomical observatory conducts scientific observations. All will be told from the perspective of a telescope operator and scientific observer; a position Cam has held at the Canada-France-Hawaii Telescope since 2015. Click here to register.

A Poetic Pelican by Doug MacDonald
A wonderful bird is the Pelican. His beak can hold more than his belly can. He can hold in his beak enough food for a week! I’ll be darned if I know how the hellican.
Dixon Lanier Merritt
Shot this Aug. 9 – 13 with Bortle 6 skies. This bird lives in Cygnus, not too far from Deneb. I processed it in the SHO palette; it represents just over 8 hours of narrowband exposure with a 5″ refractor at f/5.5.
Final UVic Open House of the Summer is a Block Buster!
Cosmic Collisions Abstract: What happens when galaxies collide? Right now, the Andromeda Galaxy is hurtling towards us, on a direct collision course with our galaxy. Surely the Milky Way will not escaped unscathed? For almost a century astronomers have been trying to figure out what happens when galaxies clash, and from that investigation a harrowing tale of starvation, cannibalism, and complicated acronyms has arisen. With today’s massive telescopes and high-tech simulations, we can hope to understand what happens when the largest objects in the Universe go face-to-face. And perhaps we can predict how our galaxy will be changed for the better (or the worse)

Press Briefing on Starlink and other mega-constellations
At 11AM on Tuesday August 25th the American Astronomical Society (AAS) and NSF’s NOIRLab will have a press briefing on the SATCON1 LEOsat mega-constellations workshop report. SATCON1 gathered astronomers, satellite operators, dark-sky advocates, policy makers, and other stakeholders to discuss, understand, and quantify the impacts of large satellite constellations on ground-based optical and infrared astronomical observations as well as on the human experience of the night sky. The briefing will be live-streamed on the AAS Press Office YouTube channel (https://www.youtube.com/c/AASPressOffice)
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
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.”
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.

Some Great Planetary Detail
Lucky Imaging of Planets and the Moon
If you want to learn how to capture wonderful images like the above perhaps you should attend the following webinar!
Tuesday, August 11th – 7:00pm ADT / 6:00pm EDT / 3:00PM PDT Nova East 2020 – Lucky Imaging: Astrophotography of the Moon and Planets Lucky imaging is a technique used to capture high resolution images of the Moon and planets. It involves taking as many images as possible, often several thousand, with a high-speed “video” camera and using specialized software to identify and stack only the sharpest images. The talk, presented by David Hoskin, will cover the equipment, software and processing workflow used in lucky imaging.
Edmonton RASCal Mark Zalik – captured this remarkable sequence on August 4th which closely resembles hummingbirds. All Edmonton content kindly relayed by Dave Robinson. Mark writes: Wonderful NLC display tonight! Nice arrays of billows formed way down near the horizon, where the twilight imparted a beautiful cinnamon colour on the NLC. A bit earlier in the display, the clouds formed an ethereal hummingbird.
