Veil Nebula

This is my second try imaging the Veil Nebula. Last fall I gave it a first shot with my unmodified DSLR and a GT81 refractor. This time I imaged it using an astro-modified DSLR and narrowband filter. This was my first use of the dual band Optolong L-enhance filter that allows my to capture Ha and OIII/Hb bands simultaneously with my DSLR. This image was processed using a standard OSC DLR RGB image workflow, and I'm giving it a go using narrowband processing next.

Imaged with WO GT81 at F4.7 (382 mm focal length) using Flat6A II field flattener/0.8x reducer, Optolong L-Enhance dual narrowband filter, and full spectrum modified Nikon D5300.

Pre-processed using PixInsight Batch Pre-Processing (BPP) script. Images calibrated using darks, bias, and flats. Stacked 51 subs (360 sec at ISO 400) for a total integration time of ~5 hours. Post-processed in Pixinsight: Cropped, gradient removal with ABE, MLT for noise reduction, Photometric Color Calibration, stretched using Arcsinh then Histogram Transformation Tool, Curves Transformation, ACDNR for noise reduction, HDR transform, Morphological Transformation to shrink stars, Local histogram transform, and Color Saturation boost.

Description: Re-do of nonlinear post-processing. Original version used STF settings for Histogram Tranformation which over-baked things a bit. Discovered that nonlinear noise reduction using ATrousWaveletTransform was killing the sharpness, so switched to ACDNR.

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.
