2025年1月23日 · Processing M42 in GIMP - a complete workflow - posted in Experienced Deep Sky Imaging: Hi guys, this is my three-parts tutorial, showing a complete workflow for editing M42, The Great Nebula in Orion, using GIMP. Hope at least some of you will find it useful.

2025年1月23日 · Hi guys, here is my tutorial, showing a complete workflow for processing M42, The Great Nebula in Orion, in GIMP. The image was taken with Skywatcher's ED80 + 0,85x reducer / flattener and astro-modded Canon 450D.

2025年1月19日 · In this tutorial I show a workflow based mostly on GIMP, for processing M42 - The Great Nebula in Orion. I took this photo using my old Sky Watcher ED 80 refractor with 0,85x reducer /...

This video is a demonstration of image processing of the Great Orion Nebula (M42) featuring a successful adjustment of star size/shape to fit more naturally to the image by Siril and GIMP....

The video above shows every step of capturing and processing the Orion Nebula (M42) with a DSLR, small telescope, and an iOptron SmartEQ mount. It then goes in to processing with DeepSkyStacker and Adobe Photoshop.

A tutorial on how to expose the Trapezium in the Orion Nebula using Siril and Gimp. Two easy methods to avoid the blown out core and still retain rich detai...

2019年4月4日 · I would like to share here my winter's project, M42, finally finished. I posted this image in another forum, so I do here a copy-paste (more or less). I followed a workflow that I found on that forum with minor variation, I would be glad if …

2025年1月11日 · This is 129 minutes on M42, using a WO ZS73III and a ZWO ASI585 at gain 252. It's best 99% of 500 by 8 seconds and 842 by 6 seconds, stacked in ASTAP, processed in GIMP. That's a lot of very short subs and two hours is …

2022年2月8日 · Stacked in DSS, processed in GIMP. For the core I did 30x20s subs; For the rest I did 125x45s & 30x60s. Total exposure times is around 2 hours. Calibrated with 35 darks, 30 bias and 30 flat frames. My setup: AT72EDII, CG-4 (motorized w/ AstroGadget EQStar Pro), Canon Rebel T6 (unmodified) DSLR; AstroTech 0.8x Field Flattener/Focal Reducer.

2020年1月17日 · Use latest Gimp to do basic stretch of the image and a bit of color balancing. Maybe try minimal approach first. When stacking image in DSS there is option for background calibration - use RGB background calibration (that should preserve nice gray background).
