Re: PST modification - idiots guide
Thanks guys for the OK, I will start ordering my list now. Hopefully pick everything up at the IAS show in November. Is anyone going?

Re: PST modification - idiots guide
Hi guys, I have finally put everything together but not in the order I expected. Unfortunately the micro focuser I bought only has a screw in top so nothing fits in it apart from my 2" -1.25" adaptor. Are you allowed to put the blocking filter directly behind the etalon? I can obtain 20cm in length in this combination only.

Yes Alexandra, that is no problem. A bit further back could be nice to see more of the sun (when the BF is small), but for HR imaging it is fine.

Hi
It will vignette the image badly moving it right behind the etalon.
If you move it put it before the CCD.
I have done a full PST Mod and I am thinking of taking the blocker I do not use out of the abandoned PST and placing it in front of a small CCD camera for prominences set up.

Re: PST modification - idiots guide
You wont have any vignetting issues with the solarscope blocker, it's bigger than the 20mm aperture of the etalon.AndiesHandyHandies wrote: ↑Tue Jan 14, 2020 8:50 am It will vignette the image badly moving it right behind the etalon.
