Getting to know the Lunt LS60

[Highburymark]

Definitely go for the 60mm DS, even though it’s painfully expensive. The resolution and contrast increase are worth it. Personally, I’ve never thought proms suffered with a double stack system - they always look similar to single stack. And I wouldn’t read too much into the sweet spot point either - every etalon is different, and it’s impossible to know how two filters will combine until you try them out. Just my 2p worth on all the issues raised.

I bought a used LS60THa with the DS50 last year. I fit the DS50 virtually every time I use the scope now. Based on my previous experience with a Coronado SM40, I find performance of the LS60THADS50 to be turely excellent.

Thanks! Looking forward to add a DS filter this summer!
