That looks a wonderful image Brian. You've captured so much Oiii & love the way it's processed.

Thanks Paul. It came out green/blue after combining, which I didn't care for. After a tweak in Photoshop I converted the green/blue into a more acceptable colour.

HOO combination of Pickering's Triangle. 8 hours of each filter, processed in Pixinsight and Photoshop. I'm in the process of capturing SII data to make an SHO image if the clouds keep away.

Beautiful image Brian. What focal length are you shooting with or is this cropped tightly from a wider fov?

 

On a side note, I recently listened to an audio book called The Glass Universe by Dava Sobel that talks mainly about the women in the late 1800's, early 1900's that did much of the glass plate inspections at the early observatories. It goes into great detail about their work and the work of the Pickering brothers and Harlow Shapley.  It's a really interesting read for those interested in the hobby.

Thanks Greg. No cropping with this image. It was taken with my Esprit 120 with no reducer, just a flattener the FL is f7.

 

The book sounds interesting, it must have been one hell of a job polishing the glass for early observatories, all by hand I presume.

Indeed, but the book is about the women that examined the glass photographic plates. The women were called computers and analyzed the glass plate images and basically did all of the work in hunting for asteroids, supernovae, variables, and figuring out the spectrum for all of the stars.
