Messier 17 Region with Vintage Jupiter-11A 135mm f/4 Lens

Plenty of cloudy nights to put together old lenses I had laying around with some of the newer cameras I have gotten recently. Had a good opportunity last night to try a configuration with a new moon and a few clouds. Pleased with this capture of M16, M17, M18, and M24 through a vintage Jupiter-11A 135mm f/4 lens made by Kazan Optical Mechanical Factory, SN 730202 (Copy# 0202 mfg in 1973). Focused manually while attached to the ASI 2600MC with a Baader UFC 2" filter changer holding an Optolong L-Pro. Guided tracking with the ASI 174MM attached to a mini scope using PHD2 software. All mounted onto a fully-integrated CEM40-NUNC - NUNC mini on mount has SharpCap 4.0 app used to acquire 200 x 60s images @- 10 C 100g, and NINA app used for plate solving and tracked guiding plus dither every 5 min. 50 Dark, and 50 Flat with Darks, through SharpCap's preprocessing before saving as FITS.

In PixInsight, Blink selected frames and only ~50 images were processed. Debayer, Aligned, and Image Integrated with drizzle data.

Cropped, Extract RGB to Linear Fit and Channel Combine, Background Neut, Color Calib, SCNR, axial-DBE, TGVDenoise, MLT, & EZ Soft Stretched. ABE, DSE, and Curves modified w/ & w/o masks to taste - Star Mask used to color saturate stars.

In a lucky shot, Image 37 at 8:54 PM EST had a meteor - the image was slightly individually processed, GAME masked to protect the shooting star, and Pixel Math was used to combine and overlay the final integrated image.

The final combined image was Annotated, Resampled, and Saved As PNG.

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.
