Doublestack with LS50F?
Posted: Thu Aug 10, 2017 7:19 pm
Hi there,
At the moment I use a Bresser 127 mm pst mod.But I have also got a LS50F filter. I learned here that I need F30 (thanks Merlin and Galosimo!). So then this would be an option:
- create a F30 beam
- use a Baader 35NM H-Alpha filter in front of the telecentric system
- attach the LS50F to the telecentric system, remove the Erf.
- remove the front lens of the PST etalon and attach the etalon to the LS50F
- leave everything else as it is. So the JMI focusser is attached to the PST etalon.
Fact is that I don't own a 3x telecentric system. But I do have a Televue 2,5x Powermate (1,25 inch). Would it be wise to try if it works by using the 2,5x powermate as the telecentric system? So then I guess the only things I need are an adapter T2 to M90 and a M90 to M50 adapter.
Any advice if it is wise to pursue this? Thanks in advance!
