Can a comet pulled into the sun be seen in an amateur’s telescope?
I have no explanation for what I watched and with great luck recorded yesterday October 29,2022. When imaging prominences on the solar limb I stare patiently at the live view video image waiting for good seeing to do a snapshot. While doing this yesterday I watched a small bright object pass quickly through my field of view and into the sun’s disc, where it disappeared. I had been doing snapshots at the time and to my delight that evening while reviewing my images, found I hand recorded a streak in one of them at that time.
My telescope setup is an old 90mm Coronado 0.5 Angstrom etalon front mounted on a 5 inch f/11 refractor with a 30mm blocking filter. A QHY 5 III174 video camera is mounted at the prime focus and operated with SharpCap software.
When the image was taken (3:20 PM CST) my exposures where 110ms. Set to record some faint arcs. The speed of the object caused it to show as a linear streak seen under a prominence arc just left of center. If it was a fast-moving plasma ball it would not be moving in a straight line. Its disappearance after going over the sun’s disc is logical considering the overexposure of the sun’s surface. ( An exposure of only 5ms is needed for that.)
The sun’s image had been rotated to make a nice composition for the final photographic image. So North is not at the top of the frame. Top is close to the sun’s equator on the approaching limb. The grossly overexposed triangle shaped prominence in the raw image can clearly be seen on the NISP image provided that day. That can help in better orienting the field of my image.
I am providing 2 images. A raw shot and a more pleasing image with the occulting disc affect added. As I have said, this object is the line appearing just under the prominence arc left of center. The image taken before this one was a minute and a half earlier so the object had not yet entered the field. With your scientific audience I hope someone can confirm that it was a comet or ?
