Question to Stephen Ramsden

Post by Valery » Sun Jul 27, 2014 10:10 am

Hi Stephen,

I know that you own or have owned a DS-II for LS152.

Can you, please, told me what the diameter of the etalon in it and what is the band wide?

.65A 60mm clear aperture etalon, I think.

I gave away both of my LS152's to other outreach groups and I purchased the LS152DS for use in Australia and gave it to Rob Black when I left so I don't have one I can measure. Sorry.

you could always ask the question on the Lunt Solar Systems FB page or just call them.
