This project has been another long-held ambition for me and has been a labour of love over the past few weeks for Steve and I on our shared rig in Spain. We alternate over three weeks the duties of controlling and operating the rig and the capture programme and have both shared the joy and frustration of the winter weather - yes even in Spain. I've been intrigued by NGC1999 and its 'keyhole' along with the faint blue reflection nebula that surround the main attractions or M42, 43 and the Running Man and am delighted to have stitched together this four panel mosaic to show their relative positions.

Processing has taken as long as the total integration, circa 40 hours, and I can foresee us adding to this data next year. There is a tiny amount of data to capture to help the mosaic in a couple of places and we hope to be able to do this when the weather clears and at the next New Moon.

Each panel has 13 x 1200s Ha; 12 x 300s + 15 x 180s + 30 x 30s Lum; 12 x 300s of RGB each. A total integration of 37.3 hrs. Tak 106, 10 Micron GM1000HPS, QSI683wsg-8, Astrodon filters, SGP for capture and PI for processing, e-Eye, Spain.

Data acquisition: Steve Milne & Barry Wilson.

Processing: Barry Wilson

Hope you enjoy.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
