Nice disk Dave, what problems are you having with the double stack?

Re: H ALPHA 6/3/21 trying out new ds pressure tuner for Lunt ls130mt terrible trouble with it
hi mark can't seem to get it tuned properly why does it not show me the filaments through the eye piece is a nice view but still no nice dark filaments and with the camera not very contrastie that could be the zwo there not that good I got so frustrated trying to tune don't know where I'm going wrong with it the image I posted is the best I could come up with should have been showing a lot more detail don't you think

I think it's a case of getting the tuning routine right, tune the main etalon first for onband view, then add second etalon and tune for maximum contrast on the filaments.
I would have said the image is single stack, so if it was double stack then tuning definitely off! Is the ds unit holding it's pressure?

Re: H ALPHA 6/3/21 trying out new ds pressure tuner for Lunt ls130mt terrible trouble with it
hi mark I did have both together at same time so think you must have to tune ss then add ds then tune that one I think pressure ok but is easy to turn than single stack is maybe have to look into that as well was thinking not going to be easy with the weight difference on the mount have to tune then park scope re balance thanks for your help will try next sunny day

I sometimes have issues tuning my 60. The 90 always seems easier.

When I had my double stack 80 (I wish I never sold that scope) , I tuned in SS then added ds module and fined tuned for contrast. I also had to rotate the double stack compared to the SS etalon. I found that 180 degrees worked best for mine.
