Photo of the Month for July, 2016

Hydrogen in a bubble of Oxygen - The Crescent Nebula

© 2016 Eric Marlatt

This image is another attempt at narrowband imaging with a hydrogen-alpha filter and oxygen-III filter. Narrowband filters out much of the light pollution and allows for imaging when the moon is up, the individual frames to complete this image were taken with the moon 75% to 100% throughout the last month. This was shot through an Astro-Tech 8" RC with a QSI683 camera with Astrodon 5nm filters, pre and post processing done solely in Pixinsight.

Monthly Meeting

      Saturday, July 16, 2016

Title: "A Brief History of Astrophotography"

Speaker: Dr. Klaus Brasch

Due to circumstances outside of anyone's control, the speaker and subject changed for the meeting. The speaker was Klaus Brasch and the subject was Daguerreotype to Digital : A Brief History of Astrophotography.

Klaus always comes through when necessary and his subject always lives up to our best expectations.

CAS Monthly Meetings and Astronomical Programs are held the Saturday closest to the First Quarter Moon at the Lowell Observatory Steele Visitor Center Auditorium (6:45 pm - 8:00 pm., unless otherwise noted) followed by refreshments, informal discussion, and observing. They are open free to the public.

Supernova


June 15, 2016 - Supernova

It is in Draco just above the bowl of the Big Dipper. I went out last night with mixed success to capture it. I could not see the Nova visually in my 10" SCT however three exposures taken at prime focus and ISO 1600 did.

Copernicus


June 15, 2016 - Copernicus

For once I enjoyed rather good seeing this side of the Peaks and managed to catch several good webcam sequences of selected craters on the Moon. The attached is a mosaic of overlapping sequences around Copernicus taken with the C-14 HD at f/22 with a deep red filter but shooting monochrome with the ZWO ASI 120MC. Images were stacked in Auto Stakkert and processed in Registax6. Probably my best effort yet and shows again that lucky seeing is everything.
