Captured by Geoffrey and Sarah yesterday, using our Lunt LS60 and Geoffrey's DMK41. They did the Registax and I joined the two panels and the prom exposures.

Very nice indeed. I am getting more and more tempted to get an LS60PT

Michael, I have been very pleased with mine and would recommend one to anyone with an interest.  As you have a Lunt 35 you will already know that the quality of these scopes is good and they do deliver.

I have to say though, that when I bought the double stack Etalon, I was initially less than impressed, it showed how small the sweet spot was until it was rotated to exactly the right place and tuned just right.  Actually I have to tune it slightly off to flatten the contrast.  I think my expectations exceeded what the product could deliver and a few more notes on how to tune and set up a double stack would have been handy.  I am sure this is something everyone has to go through.  Now that I have got it right I can get some great views, but it took a bit of getting there.

To help getting the DS rotated correctly I bought one of these:

It is a rotator for a focuser, but uses the same thread (M90) as the front mounted Etalon.  Sorry the page is only in German, the English page doesn't have any details.  With this I can keep my DS on permanently and in the same place, so it is always set up correctly, or quickly remove it and put it back in the same place.
