I am the owner Tele Vue NP127is telescope QHYCCD QHY600M with QHY accessories: QHYCFW3L and QHY OAG-M.
My scope is bright for APO F/5.2 and in future I will buy the TeleVue 0.8 reducer (currently I am using LCL-1069)
then the focal ration change to F/4.16.  I heard on Northeast Astronomy Forum (NEAF) 2021 that the 0.8
reducer for full frame will be available soon.
Currently I am using old type Baader 2" filters in cell, but I've planned to update setup.
I would like replace current filters to:
Baader L,R,G,B 2" in cell -> Baader L, R, G, B 50.4mm unmounted
Baader OIII 8,5nm -> Baader CMOS optimized OIII 6,5nm 50.4mm unmounted
Baader Ha 7nm -> Baader CMOS optimized Ha 6,5nm 50.4mm unmounted
Baader SII 8nm -> Baader CMOS optimized SII 6,5nm 50.4mm unmounted
I would like to ask has anyone experience with this new Baader filters?
Second question, which narrow band filters will be better 6,5nm or 4nm?
In this place I will mention I have a dark sky in my place 0.2 point on light pollution
