Introducing the New LS60F Unobstructed Front Mount Filter!

I have been accused of thinking too much about new products and technologies as they relate to my passion for Solar. My wife would tell you that there is something new on the horizon when she sees me staring at the fan above our bed for hours on end. There’s just something about the spinning fan that keeps my thoughts on track and allows me to work through the optical and mechanical details.. (not to mention the issues of day to day business ;)

I will never apologize for my need to improve the current technology, providing better Telescopes and Filters next month than I did last year.

Some products did very well in the short time they have been around, reaching the pages of Popular Science’s best of the year issue, and being picked for the National Geographic Eclipse Documentary from Easter Island.. What will we do next year :)…

Lunt Solar has grown to a point where we now deliver 200-300 Telescopes and Filters per month and with the Sun’s increased activity (go Sun!!!) we have  had to expanded our operations once again into the space next door just to maintain. With so many new “astronomers” entering the market thru Solar observation, (up to 50% of purchases are made by people who have never even looked thru a scope), Lunt will be looking at expanding our business, and participating in education and outreach efforts.

 LS60FHa Specifications: (single filter)

• Optical Aperture: 60mm
• Etalon: Internal <0.70 Angstrom
• Tuning: Tilt
• Focal Length: Customer Telescope
• Storage: Aluminum finished hard case with fitted foam
• Weight: 3 lbs (~1.5kg)
• Starting at: US$1,846.00 (B600)

Required Blocking Filter: (see “blocking filters”)

• B600 for standard visual use (included)
• B1200 for larger field of view and imaging applications (upgrade)
• B1800 for larger field of view and imaging applications (upgrade)
• B3400 for larger field of view and imaging applications (upgrade)

Required Accessories: (see “accessories“)

• Typically an adapter plate will be required to attach a Lunt Solar Filter to the front of a customer supplied telescope. These adapter are in stock for the more common user scopes, but can be custom made to your specific requirement.
• No adapter is needed to add a LS50/DS module to a LS50F.
• More information see: “adapter plates“.

**Lunt does not phyically contact the etalon for tuning. We avoid any mechanical/physical contact to the etalon filter to avoid issues such as pinching and differential stress which could lead to banding, astigmatism, and soft resolution caused by un-uniformity of the mechanical systems and resultant optical spacing. (more on this in a new post).
