Now my third PST-Mod

Post by Solar-Cologne » Sat Nov 14, 2015 9:24 am


The next step, i want more Aperture.
I use an old Bresser 6" f8 FH-Refractor, shorted the Tube for 110mm, in Front i found a second-hand 135mm C-ERF.
At first i use the original PST, ist ok but not the Hit
Then i became a second-hand Conversionskit, to remove the PST-housing, from Oliver Smie, so I got to know Oliver.

And then the Clouds are coming soon..... :D
No Sun.
Two weeks later i go to a german H-Alpha-Meeting in Rüsselsheim near Frankfurt/Main.

My first-light....ohje. I put it on my NEQ-6 and the Leader of the Meeting looks through at first.
He looks and looks....three minutes later i sayed to him, what is happend.
I thought , he sees nothing.
Than he say, wonderful.....a stone fell from my heart. :D

Later we tested in my Setup the Coronado BF10 and, terrible, many reflections and worse H-Alpha.
This Scope needs a Barlow, i use the Zeiss-Abbe-Barlow.

With an 12,5mm Microscope-eyepiece and a black cloth over my head, i came to 192x, assuming good Seeing, wonderful contrast on the disk and the little. little Prominences, with original BF5 !
My Neighbour at this Meeting, use an 110mm Apo with heated Daysstar...he was disappointed, because he invested a lot of money..... :D
I like this PST-Mod....get it better ?
YES....but not with the PST.....

sunny Greetings :D
