North America Nebula (NGC 7000)
© 2022 Klaus Brasch
Who doesn’t love the North America Nebula (NGC 7000)? On really dark, transparent nights you can actually spot it by naked eye close to Deneb in Cygnus. What we tend to forget is that this enormous start forming complex, about 1,700 LY from us, also includes the Pelican Nebula (IC 5070) and additional extended nebulosity and dark dust lanes.
This image, taken with a TMB-92 f/5.5 refractor and modified Canon 6D and IDAS LPS-V4 filter, covers about 90% of the brightest portions of this complex. This mosaic was composed from 8 x 2–3-minute frames shot at ISO 3200. Images were stacked in Affinity Photo and then processed in Photoshop CS6.
The featured photograph is any astronomical photograph provided by one of our members. If you are a member and have a photogaph you would like to submit please send the request along with the photograph and description to: firstname.lastname@example.org.
We are accepting photographic inputs for the CAS CY2023 calendar. Photos captured between Oct 2021 and 1 Nov 2022 will be accepted. Submission is open to any astronomy subject including atmospheric phenomena, club supported events or images of one's personal observatory and telescope setup. The calendars will be produced by VISTAPRINT.
All photos should be submitted in an ~ 8" x 10" JPEG format at 300 dpi. This will meet VISTAPRINT calendar production requirements and avoid my having to perform editing on them. Submitted images, to protect the club, must have your name and a copyright release statement imbedded in them, i.e. NAME©2022 Released to CAS Use. Submit your images to me at email@example.com no later than 1 Nov 2022. Price will depend on how many we order but is expected to be approximately $20/ea. A link accepting orders and to make payment via PayPal will be placed on the CAS home page in November. This delay is necessary to take advantage of holiday sales. Only orders placed through the web site will be honored.
Contact me if you have questions or problems formatting your image or inserting the copyright release statement: firstname.lastname@example.org
Monthly Meeting for September
Saturday, October 8, 2022
Dr. Padraig Houlahan
Because of technical issues with the September meeting Padrain's meeting it is being repeated again for the October meeting.
Note for this meeting only it is taken place in the Slipher Conference Room which is in the Rotunda building.
Title: “Seeing Differently - The Science behind the Webb Telescope”
Padraig will be discussing the science of spectroscopy, its connection with the Webb Telescope, and why thee spectroscopic results will greatly enhance the science of Astronomy in the near future. There will also be a demonstration of the spectral differences of various elements as observed through small spectroscopes.
Padraig Houlahan received his BA in Theoretical Physics from Trinity College Dublin, Ireland, and his MA and PhD in Astronomy from the University of Texas, Austin.
Padraig was Director of Information Technology at Lowell Observatory, and in 1995 Asteroid Houlahan (8407) was named in his honor. He has taught at both Coconino Community College and Embry-Riddle Aeronautical University in Astronomy and Physics.
CAS Monthly Meetings and Astronomical Programs are held the
Saturday closest to the Full Moon at the Mars Hill Campus of
Lowell Observatory, Hendricks Center for Planetary Studies
Auditorium (6:45 pm - 8:00 pm., unless otherwise noted) followed
by refreshments, and informal discussion. Meetings are open and free
to the public.
