First-Light for Rebuilt Solar Refractor

This is the first full-disk H-alpha image for my rebuilt early Solar telescope. I have been imaging with the Detlef Schmidt-built folded refractor for years. Before that I had a small refractor with a custom-made telecentric and Daystar 0.55 angstrom filter. That gave me about 33% of the sun's disk. What I wanted was a full-disk image system. Detlef agreed to modify the original small refractor for that purpose by reducing the appiture. This is the result.

Along with the modified refractor (now f/28 with a FL 1250 mm) and the Daystar 0.55 angstrom filter, I acquired a QHY 294 Pro MM for imaging. This gave me a FOV that easily got the full sun disk, with a little to spare.

The posted image includes both the sun and a picture of the modified refractor on my 10 Micron GM 1000 mount. This is image number one. They should get better with a bit of practice.

Now I can get up close with the 5 meter folded refractor and get a full disk with this smaller refractor. The best of both worlds.

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.
