Sun in Ha - June 26, 2022

Acquisition type: Lucky imaging

The Sun in H-alpha on June 26, 2022. I played around with different imaging trains using an ASI178MM with the Lunt50 and seem to get the best consistent results with a 2x barlow (FL=700 mm, F/14) where the ideal F/# for planetary based on 4x pixel size is F/12. This configuration provides improved image scale over my previous full disk setup using the ASI174MM which has much larger pixels...

Imaged with a Lunt LS50Tha (with feathertouch focuser and ZWO EAF), Lunt LS50C compact double stack filter, Coronado Cemax 2x Barlow, ZWO ASI178MM. Imaging train was configured to give ~F/14 (FL=700mm). Image capture using Firecapture. Stacking in AutoStakkert3 (best 25% of 1000 frames). Full disk panorama generated from 2 sub images using Microsoft ICE. Processed in ImPPG (sharpening). Colorized images using Solar Live View.

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.
