Maybe relevant maybe not but thought I'd put it here anyway.
Using a Baader D-ERF (Red glass) on my 152mm frac I find the exiting beam to be cool & not warm, Baader states that the D-ERF prevents thermal turbulence in the tube, prevents focus shift & stabilizes centre wavelength drift due to temperature changes.
With the Quark attached it appears to stay on band as required & the tuner acts as it should as & when I need it to.
Does ambient temp play a part, having had this setup pointed at the sun for as long as 7 hours straight in summer & the Quark performing as it should I would say no, I am sure other user's may had had issues though.

As I said maybe not relevant.

Back to the Ha filter specs...

TheSkyBurner...good to know it has promise. I wasn't sure if the IR leak as beyond the 1,000nm and didn't show up on standard plots.
