This expansive field of nebulosity shows the heart of Cygnus from the Crescent Nebula to the Tulip Nebula.

Gallery / IC 1396 Narrowband Colour
« on: 2019 August 12 18:10:26 »
This was imaged with a one-shot colour camera (QHY367C) and an Optolong L-eNhance filter. All pre- and post processing in PI, of course!

Gallery / North America Nebula Region
« on: 2019 July 29 17:24:38 »
I continue to be impressed by both the Optolong L-eNhance filter and the QHY367C one-shot colour camera for this type of target.

Gallery / Veil Nebula
« on: 2019 July 19 06:01:32 »
This is a first-light image for a new camera (QHY367C) and narrow band filter (Optolong L-eNhance) designed for one-shot colour cameras. The filter passes Ha, H-beta and O3. This image was acquired under intense moonlight, and I'd expect this filter to also perform well under light-polluted skies.

Looks like we might get a stretch of four clear, relatively moon-free nights next week! I will probably shoot some more in Cygnus, maybe around gamma-Cyg or the Crescent Nebula region where there is some nice O3 to be found.

Clear skies,

Gallery / Globular Cluster M5 and dozens of galaxies
« on: 2019 June 19 09:22:06 »
This is M5, one of my favourite globular clusters. This image also shows dozens of distant galaxies; some are shown on the included annotated image. This was the First Light image for the Eagle 3 Pro computer which controlled all the equipment. It performed flawlessly.

More equipment updates coming soon :-).

Gallery / Deep Exposures on M3 and M13
« on: 2019 June 01 08:02:17 »
I went deep on both of these objects to pull in the many tiny galaxies dotted around them. Enjoy!

Hope to see you there!

Gallery / Sh2-232 and -235
« on: 2019 April 01 08:15:59 »
These two objects are both in Auriga, about 3 degrees from more famous IC405 and 410. This is pretty much all I acquired in February and early March.

Gallery / Whale and Hockey Stick
« on: 2019 March 16 18:48:42 »
NGC 4631 (top left) and NGC 4656 (bottom right) are known as the Whale Galaxy and Hockey Stick Galaxy, respectively. The Whale is distorted due to its interaction with NGC 4627 just to its left. Both are about 25 million light years away. The Hockey Stick, about 30 million light years from Earth, is distorted by a small galaxy just off the tip of the “blade.”

Gallery / NGC 5053
« on: 2019 February 09 10:33:46 »
Globular Cluster NGC 5053 doesn't get much love because it's near M53 and some nice galaxies. But you know I like these overlooked objects! I imaged this in 2015. My post contains a link to the previous version. I like this one better (or would not have posted it).

Gallery / Opportunistic Imaging: M37
« on: 2019 February 06 17:49:02 »
This is my shortest exposure for a deep-sky object: 25m on M37. Just 1 red, 2 green and 2 blue 5-minute sub-frames. Shot during an unexpected 40m clear spell while I was doing some troubleshooting a potentially bad USB cable.
