Product Info
Manufacturer Description
The Lunt LS60FHa is a 60mm aperture (no central obstruction) integrally tuned etalon for use on any customer supplied refractor.
These Hydrogen-alpha Filters are designed to retrofit (adapters required) the customer supplied telescope for use during the day. They are easily removable so that the scope can continue to be used for night observing.
Because the LS60FHa has an estimated bandpass of <0.70 Angstroms it is capable of providing high contrast views of both surface and edge detail. Adding an additional etalon (double-stacking) will reduce the bandpass to ~<0.50 (dependent upon scope) allowing for higher resolution viewing and/or imaging. The part number LS60FHa is offered for this purpose or for those who already have a Lunt blocking filter. A Lunt blocking filter must be used with Lunt Ha filters at all times.

The Sun in Hydrogen Alpha
Pros:Quality Lenses,Easy to Use,Accurate,Lightweight,Compact,Strong Construction
Cons:None
Comments:This is a super quality filter. The construction was great as well as carrying case for it. It really pumped up the contrast when used with my Lunt telescope. I used it on the front of my 80mm Lunt telescope and it made the surface detail pop and I was able to see proms easier.
