Will this work to get the Quark parallel to the light cone?

I have read about the Glatter Paralyzer in the past and I am wondering if this will help to get the Quark parallel to the telescope light cone. So this will be inserted into the focuser drawtube and then the Quark will fasten to the Paralyzer with its 1.25 inch insertion.

I have arranged some other adapters that will all screw into each other as well as the Quark, to give me a "no clamping" solution to my camera and focal reducer.

In other words, the only place I need to get things orthogonal is in the attachment of the Quark to the focuser. The Glatter paralyser seems the best solution for now. What do you guys think?

Don't waste your money. The paralizer just makes parallel the object you are putting in it (the quark) to the paralizers internal 1.25" diameter; what makes the paralizer parallel with your focuser? It's no different than putting the 2" quark fitting straight into the scopes 2" focuser.

I would just get used to Ha observing with the quark first and finding the on band position.

Mark, I was afraid that this might still be the problem... Well at least I found some adapters so that the rest of my imaging train consists only of screw in adapters.

How will I know when I have found the on band position? I spent some time today fiddling with the dialing knob. The best contrast and most field uniformity seems to be at about +4. This seems like a lot. Still, what are the criteria in finding the on band position? Is it contrast? Field uniformity?

Brett,
On band will show maximum contrast. You're effectively looking "deeper" into the Ha absorption line.
One reason I didn't invest in a Quark was the fact that it may not handle ambient temperature much above 40 deg. C, common here in Oz - it run's out of temperature control. The setting for best performance I think will therefore depend on the local ambient conditions.
