This will include an overview on types of light pollution and the impacts of light pollution on ecosystems and humans\, including health\, culture and public safety. Victoria will also delve into RASC’s Dark-Sky Site Program\, including the different types of designations and existing RASC designated Dark Sky Sites. Finally\, Victoria will also go over some of the additional tools being developed by the National LPA Committee to support RASC Centres in addressing light pollution and ways that members can get further involved. \nBio: Dr. Victoria Kramkowski is a professional in the fields of environmental planning and climate change\, with a focus on working in various governmental sectors\, including provincial\, municipal\, and other governmental agencies. Most recently this work has extended to protecting and rewilding the night sky and Victoria is a member of the RASC National Light Pollution Abatement Committee\, where she is developing a toolkit for RASC members to advocate for night sky protections. Victoria has worked in academia\, independent consulting\, and the public sector and her current role in government relations for a conservation authority includes working with\, and advocating to\, various levels of government\, as well as private landowners\, community groups and other organizations and agencies in order to move forward environmental protection projects. Victoria has a PhD in environmental planning from York University and is also a member of the RASC National Science Committee and RASC Toronto Centre. \nRASC Light Pollution Abatement website \n\n  \nTitle: Building a Museum in a Time of Plague: the Dorner Telescope Museum \nSpeaker: Randall Rosenfeld \nAbstract: The Dorner Telescope Museum was conceived in 2019 through the generosity of long-time RASC member Rudolph Dorner (1948–2022). Its goal is “to tell the story of the telescope in Canada—people\, instruments\, practices—through unlocking the potential of glass with a story”. Tonight you’ll learn  something of the scope of the project—its acquisitions to date\, the nature of the planning and design process to bring it from conception to reality\, and planned programs to benefit RASC members\, and the wider community. \nBio.: R.A. Rosenfeld is the Society’s Archivist\, and the Director of the Dorner Telescope Museum. He has a particular interest in old observational records\, and occasionally publishes on them.

From recommended filters to advanced processing techniques\, see why APOD-worthy images are possible from the backyard. \nBIOGRAPHY: Trevor Jones\, also known as AstroBackyard\, is an experienced amateur astrophotographer and content creator who shares his years of experience and knowledge with others to help improve their skills in astrophotography.  \nBefore AstroBackyard\, Trevor spent many years as a graphic designer\, marketer and creative director and has since used these skills to create a brand around the hobby of astrophotography. Trevor is known for his beginner level approach to explaining astrophotography and has been involved in the greater community as a photography contest judge\, public speaker and dark-sky advocate. \n  \nTrevor is from Niagara\, Ontario Canada and enjoys camping with his family and running.

The program focus is on the debris not the original crater. In this case\, the original crater shape is not critical. Instead the focus is on the origins\, paths\, and landing locations and conditions of the debris. The program shows the debris being tossed from the impact\, and generates the debris from random number allocations of different sizes\, speeds and launch angles\, and then applies gravity\, Earth’s rotation\, atmospheric drag\, momentum until the debris particles hit the surface of Earth (or continue into space in orbit around the Sun). One can then look at any point on Earth and see the secondary craters formed from the debris\, with the craters colour coded to let you know which portion of the comet hit. Also\, the impact angle and speeds are listed for each secondary crater. This is a demonstration of a style of impact rarely studied\, but I believe happening far more often than previously thought\, and I believe the source of Lake Michigan itself which is of similar size and shape to  Mars’ Orcus Patera crater. I have previously talked about my theory that Lake  Michigan is a skip impact crater. This presentation is on the software simulating that event to see if it produces the Carolina Bays (It does) and showing some other simulations of skip impacts on Earth. \nBrian Gibson First Light with the new Sharpstar 130mm f2.8 HNT Astrograph \nI photographed the Triangulum Galaxy M33 with it from my deck in Thornbury (Bortle 4).  I mounted it on an iOptron CEM40G equatorial mount.  It was one of those very rare clear nights in October. \nRandy Attwood   A preview of the November 19 Lunar Eclipse \nLink to the meeting URL:https://rasc.optunia.me/event/potpourri-night-7/ CATEGORIES:Potpourri Meeting ATTACH;FMTTYPE=image/jpeg:https://rasc.optunia.me/wp-content/uploads/2021/07/Picture1.jpg END:VEVENT BEGIN:VEVENT DTSTART;TZID=America/Toronto:20211015T193000 DTEND;TZID=America/Toronto:20211015T210000 DTSTAMP:20260419T164212 CREATED:20210730T155300Z LAST-MODIFIED:20211012T190120Z UID:1642-1634326200-1634331600@rasc.optunia.me SUMMARY:Potpourri Night DESCRIPTION:Host: Randy Attwood \n\nShriya Naik   A review of the book: “Advanced Skywatching: The backyard astronomer’s guide to starhopping and exploring the universe” – A Nature Company Guide by Robert Burnham\, Alan Dyer\, Robert A Garfinkel\, Martin George\, Jeff Kanipe and David H Levy\nSimon Claughton – Postal History Apollo 15\nAdina Stan This summer I visited the Sulphur Mountain Cosmic Ray Station in Alberta.
