Sun in Ha - June 9, 2023

Acquisition type: Lucky imaging

The Sun in H-alpha on June 9, 2023 featuring AR3331 and a nice arch prominence. The single stack images came out really nice with better detail in the proms than the double stack images.

Imaged with a Lunt LS50Tha (with feathertouch focuser and ZWO EAF), Lunt LS50C compact double stack filter, 2.5x Televue Powermate, ZWO ASI290MM. Imaging train was configured to give ~F/18. Image capture using Firecapture. Stacking in AutoStakkert3 (best 25% of 1000 frames). Processed in ImPPG (sharpening). Prom image generated from surface image using curves adjustment in ImPPG. Combined surface and prom images using GIMP. Colorized prom image using LuSol3D and Solar Live View.

Original version: Surface (Inverted) image combined with prominence image, single stack

Rev B: Surface image combined with prominence (inverted) image, single stack

Rev C: Prominence image processed with LuSol3D and Solar Live View (colorized version), single stack

Rec D: Prominence image processed with LuSol3D and Solar Live View (black and white version), single stack

Rev E: Pano (inverted surface + proms), double stack

Rev F: Pano (proms), double stack

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.
