Small, bright object oft mistaken as a star while eyeball observing. This is my better image from past attempts. Taken at Okie-Tex, with a problem with something in my optical train. This affected all of the 21 objects I imaged during this time. Normal Bahtinov focus images, red laptop filter, linear stretch and possibly the physical post operative and neuropathy pain hid the problem until I started to process these images. This one better due to the short exposures. Some detective work to be done. Plenty of suspects in the optical train causing odd lobed comatic flare across the entire field with the brighter stars. Poo.
