M78 Flame Horsehead Running Man

First Light with SmartEQ Pro mount. 39x90" unguided, using DSLR and rough polar alignment with PS align on my iPhone. Had a heck of a time figuring out how to enter the Time Date and Site coordinate information, got it figured out. Did a one-star alignment to Betelgeuse (which was easy to spot with its dim orange color), it slewed to NGC 2023 directly in the center of the frame. Slightly under an hour of integration time, will be adding more once the weather clears up.

The original image is my last attempt on the Horsehead and Flame with my old Celestron CG3 EQ2 mount.

Description: Updated: first light with SmartEQ Pro mount, 39x90 seconds...in hindsight I was pushing it a bit because the stars are trailed, but it was still exciting to see the light gathered.

Description: Reprocess, started from scratch. DSS with 2x drizzle, 20 darks 20 bias (taken after imaging session), 20 flats. Kappa Sigma light/Median setting for bias/flat/darks. Pixinsight for ABE, Multiscale Linear Transform, Masked stretch, Morphological Transformation to reduce star size, Histogram transformation, Unsharp Mask, Curve stretched. Used a Range Selection mask for each step, generating a new mask for every step. ACDNR, additional noise cleanup. Lightroom for removing CA in the purple range and additional NR. Photoshop CS3 for additional level adjustment and layer blending. Downscaled image size from the 2x drizzle prior to export.

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.
