I got to try out my new quark on a celestron 102 SLT refractor that I am modifying (new focuser, etc). As with my LS50, I have it piggybacked on my Evo 8. It looks ridiculous and totally overloaded but the quark/refractor actually weighs less than the Lunt (those little things are heavy!)
Anyway, for a first try, I was able to get a pretty good image but the quark tuner didn't seem to have much effect. I went from all the way CW to all the way CCW in about 2-3 click increments and I waited for a green light each time. I saw proms and a bit of surface detail pretty much all the time but not much of a noticeable difference along the way. The image was larger than in the Lunt but the surface detail was about what I would see in single stack mode. I only have experience with the pressure tuner on the Lunt and there is a huge difference between in tune and out of tune so I was assuming the same thing here. Any thoughts? I am wondering if this is too much aperture for the my conditions so I was going to try to reduce to 80 mm and see if that helps.
Also, since the tuning process can take quite a bit of time with 5 minute waits at each step, I was wondering/hoping if you can typically find a good setting and just leave it for the next session. Is this possible or just wishful thinking? My sessions are usually pretty short with only having a 30-60 minute window after work before the sun slips behind a roofline and the Lunt was about as grab and go as you can get.
