Star Burst Pattern with FSQ-106N
Hi Guys,
In my recent images I have noticed a star burst pattern on brighter stars, predominantly near the edge of the frame.
I am using a FSQ-106N with a STL-11k mono and a MMOAG.
Have tried several things now to see if I can trouble shoot the problem but I am running out of ideas.
So far, I have removed the OAG prism from the light path to no effect, took an image with no filter to eliminate the possibilty of reflections from filters.
The only thing left for me to do next is to remove the MMOAG and attach the STL directly to the FSQ-106N.
I have attached an image of the artifact I am getting.
Hoping some of you have had experience in having seen this before and might be able to shed some light on this problem.
I am reluctant to think its the optics of the FSQ as it has a very solid track record being a TAK and all.
BTW, this is a very small sub-frame of the original image, focus was dead on and it was taken in Very Dark skies (Hawker) with no moon, or near street lights and no stray sources of light.
Cheers
Mark
