I'm wondering what others have done to kill the reflections from bright stars with the ever popular QHY8 cameras.

I note that some have added a T-Thread extension and put the original nosepiece on the end while others have replaced the nosepiece with a 2" adapter and plonked an IR/UV filter on the end.

It seems the idea is to move the filter further from the sensor yet I've heard others have screwed a t-thread filter directly into the camera.

What is the best option. I tried the 2" adapter option tonight and the sensor had ice on it pretty quickly. However icing aside, it made a big difference in these 200sec unguided shots.
