The Lumicon LF5005 - 1.25" Filter Selector- Low Profile Focuser Combo for Newtonian on 3.5" Base is a combination of our LH2020 - Low Profile 1.25" Focuser for Newtonian on a 3.5" Base and our LF5012 - Multiple Filter Selector 1.25". The price of the Combo is $49.95 less than if purchased separately.
The Combo is for the user who is looking to replace their high profile focuser for a lower profile focuser that will allow for the use of a variety of accessories even with the Multiple Filter Selector installed.
The 3.5" base is square with 3.5" per side. The mounting holes are 2.75" center to center. The 3.5" base can cover focuser holes from 1.5" to 3.3" in diameter. For focuser holes smaller than that, up to 2.7", use the focuser with the larger base included with LF5000.
When at minimum, the Filter Selector eyepiece holder will be 4.25" above the feet of the base. The focuser has 1" of travel at 1/2" per turn.
