I took delivery of a brand new Lunt LS60T Ha with a 1200 blocking filter. Of course there was terrible weather for days and when the sun was out I had to work late. So today it was sunny albeit a little hazy at times. I mounted the scope and aligned on the sun. Got to focus with a 25 mm TV plossl. So far so good, no features yet. Followed the directions to burp the pressure tuner and I watched the image get a little contrast and saw a prom I think. After hearing the little pop/burp I tried to tune it again. I had no success. Thought I saw a change but I think it was my eyes getting fatigued. Rested for awhile and went back, but still absolutely no details. I've owned a Quark for the past 1,5 years so I know what to look for in features. All I'm getting is a blank orange disk. It isn't cold yet (60 F) so I don't think it is the blocking filter being too cold. I tried to add a touch of grease to the pressure chamber wall and I feel some resistance when the O-ring seats properly. I've cranked it all the way in until it bottoms out which isn't easy.
Anyone have suggestions? Right now it has clouded over and rain tomorrow. My next chance for any observing is next weekend which is forecast to be sunny but who knows. I'm not in panic mode yet but I'm more than a little concerned. Thanks in advance for any help or suggestions.
