Transcript video of the meeting
- Mark Wheen at Pearson College wants to train some people to operate the 25″ telescope – members should contact Bill Weir if interested
- Astrophotos from Victoria Centre members
- Intro from John McDonald
- Brock Johnston – online gallery
- Using new ASI 2600 camera (one shot colour)
- Cocoon Nebula
- Fireworks Galaxy
- Andromeda Galaxy – 3 nights
- Deer Lick Group – SCT Celestron Edge 9.25″
- Jupiter
- Using video from ASI120 OSC planetary imaging camera
- De-rotated about 1 minute clips
- Saturn
- Using video from ASI120 OSC planetary imaging camera
- Doesn’t need to be de-rotated
- Processing of planets: PIP > WinJupos > AutoStakkert
- Pick objects that are rising in the eastern sky, so there is time to image them
- Using new ASI 2600 camera (one shot colour)
- Dave Payne – online gallery
- Rosette Nebula – taken 10 months ago
- H2 cloud, UV radiation
- Big – about 1 degree across
- 127mm refractor, 660mm f/l
- Tulip Nebula – Sharpless catalog
- Smaller
- CDK 12.5″ 2540mm f/l
- H2 cloud
- Note Cygnus X1 on left side of field of view, some purple clouds driven by the Black Hole’s accretion disk
- Iris Nebula
- Much closer than the other nebulae
- Blue colour indicates that this is a reflection nebula
- PAH – life can be formed when this is present
- Rosette Nebula – taken 10 months ago
- Dan Posey – online gallery
- Rho Ophiuchus – short focal length – modified dSLR, camera lens & small tracker
- Comet NEOWISE – modified dSLR, camera lens & small tracker
- California Nebula – tri-band filter with Askar 108mm 600mm f/l
- Uses Starnet – to subtract and add back the stars using neural net processing
- M81, M82 – Milky Way background structure revealed by doing some exotic processing technique
- Eagle Nebula – imaging from a balcony downtown at 400mm using SBIG 8300 – compared with imaging from the VCO 16″ TPO RC computer
- NGC 7318 interacting galaxy pair – imaging using the Plaskett telescope
- RASC Victoria might have imaging time on the Plaskett in October, so send Dan any objects of interest (if you are on the Active Observers’ email list)
- Garry Sedun – online gallery
- XM2000 monochrome camera, 20″ Newtonian astrograph
- Horsehead Nebula
- M51 galaxies
- Moravian 16200 imager, 20″ Newtonian astrograph
- M82 galaxy revealing the jet –
- Jellyfish Nebula – colour and monochrome wavelengths – star colours still need work
- M81 galaxy and blue dwarf companion galaxy – two versions
- XM2000 monochrome camera, 20″ Newtonian astrograph
- John McDonald – online gallery
- Halton Arp’s catalog of peculiar galaxies
- Book: Lonely Hearts of the Cosmos: The Story of the Scientific Quest for the Secret of the Universe – Dennis Overbye
- Arp objects imaged by John: 213, Whale & Hockey Stick galaxies (281), 273, M101, 270, 214, 41, 273, 9, 316, M82, M51, Stephan’s Quintet or Hixon Group (319), Heron 84, 333, 270
- Discussion among the astro imagers on technique, optics, sites, conditions
- Scientific Narrative – Ken Atkinson
- Ventu Sky – interesting weather maps
- Human genomes
- Highly magnetized and rapidly rotating white dwarf as small as the moon
- Books
- Birth of a Theorem – Cedric Villani
- Cantor’s Dilemma – Carl Djerassi
- Newton’s Darkness: Two Dramatic Views – Carl Djerassi
- Berlin in lights – the diaries of Count Harry Kessler – mentions dining with the Einsteins and other famous people
