About DARK|SKY
 
AMI DARK|SKY is an astro|photography club that meets on select post-COVID nights under the clear, new moon, Bortle Class 5 skies of Denville. AMI members and incoming initiates are welcome to join Morris Catholic faculty from multiple departments as they tinker with photographic gear mated to astronomical toys.
DARK|SKY Calendar Events
 
2 September 2021 | Impromptu meet with about 7 telescopes and a star-studded cast (get it?): Venus, Saturn, Jupiter (and its moons), Andromeda Galaxy (M31).
 
24 June 2021 | Finally some decent weather! 
 
*Canceled* 10 May 2021 | New Worm Moon. See below.
 
*Canceled* 12 April 2021 | New Snow Moon. Bring your own telescopes for the first (hopefully) post-COVID get-together on the Soccer Field at Morris Catholic High School. The event will feature food, Fr. Brian's lavish catadioptric telescope, Dr. Ciar's star-tracker photography rig, and his 10" Dobsonian Telescope. This event is weather-permitting.
 
 
 
Orion Nebula
Figure 1 | The Great Orion Nebula. Located in the constellation of Orion (in the sheath of his sword—for reference, see Figure 2), this famous nebula was photographed on 1/16/2021 from Flanders, NJ, using a Canon EOS RP with a Sigma EX DG OS 70-200mm f/2.8 lens and a 2x Sigma APO Teleconverter at f/5.6, and ISO 40,000. The rig was cropped in-camera at 1.6x for a total raw focal length of 640mm. 27x1s images were integrated within DeepSkyStacker and edited in Adobe Photoshop CC v. 22.1.1. The imaging rig was not tracked to a sidereal rate (plain-old tripod! See Figure 3!).
 
Messier 42
