It'd be nice to see some widefields with your TSA and your STL11. That could be a really nice combo.
Your 12 inch is the go for these sorts of dim, small targets.
I like to stretch how far I can go with the aperture.
That TSA has produced some lovely images and it is the scope I have owned the longest now.
You make a good argument about the TSA and the STL. I had considered getting the adapter made up for these two components. The field of view might just vignette though. I am using a reducer with TSA now and I get some vignetting with the QSI. Thoughts?
I will get the 12 inch going first before contemplating this next move.
