Description

It is quite a "fight" to deal with the reflections when using the Intes M703 as a solar telescope. After experimenting here is what I came up with:
Baader D-Erf
Intes M703
1,25 inch Baader 35nm
PST etalon
2 inch Beloptik UV/IR cut on KG3
Lunt B1200, blue glass removed.
Biggest difference was when I changed the 2 inch Baader 35nm filter for a 1,25 inch. This filter is mounted just before the front lens of the PST etalon.

The coloured version, on the top right you can see there are still some reflections.
