Lunt Blocking filter with Solarmax etalon?

Post by hopskipson »

Before I try this out, can I use a Lunt blocking filter with a Solarmax II external etalon? I want to use the DS etalon from my SM II 90 mm on my Explore Scientific 102 mm f/7 with my Lunt B1200, if possible.

No probs with the blocker.

Whether the DS etalon will work as a SS is a different matter, but, try it...

Thanks again Mark! Good to hear I won’t need a new blocking filter. I’ve read the SM2 manual and it seems like when they sell the etalon with a blocking filter it is the same as the DS etalon with richview tuning. I’ll report back on how it works out. I’m guessing I won’t need any tilt?

So I tried out the Solarmax 90 DS etalon with the Lunt 1200 blocking filter and was quite pleased with the results. The above is with minimal processing and below is a little more aggressive. I feel that the tuning is very uniform and there's not much of a gradient. The conditions were not ideal, some haze and poor seeing at around 1p.m. Now I'm wondering how another DS etalon might work.
