Description

Orion will be leaving us soon ☹ for another season and I’m Just getting around to processing the broadband data from Grand Mesa Observatory on the Horsehead (IC434) and The Flame Nebula (NGC 2024) using the QHY600M monochrome CMOS on the TAK130 and I was so impressed with the luminance data that I decided to share this image, “besides I just love black and white photos”. This is a 56% crop of the original and just 43 x 2 minutes exposures with no noise reduction whatsoever applied to the image for a total integration time of 86 minutes. Also visible in this image in quite good detail NGC2023, IC 435, IC 432, IC 431 and of course the triple star system of the blue supergiant Alnitak is also seen in all its glory with not so much of a halo.

We have the honor of testing the new QHY600 60 Megapixel Full Frame Monochrome CMOS camera for QHYCCD.

This setup is available immediately for people wanting to subscribe to Grand Mesa Observatory's system 1. https://grandmesaobservatory.com/equipment
