spooked velociraptor

Hey, thanks! Is there any way of fixing this myself or can it only really be fixed by WO themselves?

Yeah that's what I was thinking looking at other posts here. Any idea whether it's screws in the OTA or the flatteners?

Hey, I recently bought a z73 second hand on astroukbuysell. I'm really happy with it, but I'm getting a few issues with stars that I'm trying to figure out, and wanted some advice on. I've heard that there can be some issues with the screws appearing in the field of view, but before I start messing around with it I thought I'd post here to get some external advice. A picture of the stars (with the flattener 73a flattener attached) is below. The image take was perfectly focussed (I used a bahtinov mask to perform the focus). The flattener is set to 11.4mm which from what I've heard is the distance required for a DSLR, which is what I'm using for my camera. Thanks in advance :)
