- Questions & Answers
Product QuestionsCan you add this to a Lunt LS60T Ha? Lunt Solar Systems said I could use a 50mm to doublestack on my LS60T Ha. I want to achieve better detail of the sun...New to solar scopes. If I add this to a LS50Tha that has a B600 blocking filter. Do I need a 2nd blocking filter?Question by: astro_1 on Jul 23, 2014 8:21:39 AMNo, you only need one blocking filter in the back of the scope. The blocking filter is in the diagonal anyway, so there is no way to add a second one into the light path. This double stack filter is all you need to improve your scope's contrast.Answer by: Chris (Admin) on Jul 23, 2014 12:38:47 PMHi,
Can I use the LUNT LS50C COMPACT DOUBLE-STACK FILTER with a Lunt B1200 blocking filter on a regular non-solar telescope? Also, may be adding a Neutral Density photography filter with a 4 factor aprox.?
If yes, what are the Metric treads on both ends of the LUNT LS50C COMPACT DOUBLE-STACK FILTER?
If not, do you have a Lunt 50mm diameter alternative in stock for H-Alpha to use in the telescope front end with the B1200 blocking filter for a non solar telescope?
Alv,Question by: ALv. on Mar 25, 2017 3:49:00 AMUnfortunately, no. This filter is not capable of being used as a primary etalon - only as a double stacking filter. You would need to use a standard 50mm filter and blocking filter such as this: LS-50FHA1/B12 - https://www.optcorp.com/ls-50fha1-b12-50mm-h-alpha-filter-b1200-for-1-25inch-focusers.html. You would need to contact a machinist to have an adapter made for this filter. The scope-side threads are M90x1.Answer by: Chris Hendren on May 3, 2017 12:59:00 PMOnce the LS-50C is installed to the LS50Tha, is there a preference to tune one of the 2 etalons before the other ?
The instructions that came with my LS50tha only covers the operation of the instrument without the addition of the LS-50C.
