The New Astrocrumb FilterSlide Mark II
This new design is intended to be used in conjunction with the Feather Touch Focuser via an adapter ring. As you can see in the pictures below, the adapter ring screws into the nose of the focuser tube.

I highly recommend adding my ODT(Omega Dew Terminator) on any scope that the FilterSlide is out in the open. As you can see in the pictures, the exposure to the open sky will invite the unwanted guest known as dew or frost. I don't like that guest. To be powered by any standard dew controller. If you don't typically have dew issues, then you can skip it.
Please note that the ODT can be purchased as an add-on by the customer at a later date. But the installation at the beginning, by me, ensures a perfect fit and is anchored via ties through the slide. Installed by the client, I provide sticky tape anchors that work, but are not as bomb-proof. Unless of course, you would like to drill holes in the slide yourself.
-And the Cases-
-And another big, new option-
The new FilterSlide and accessories can be custom made with additional filter positions. You can order up to as many as 8 filter holes in one slide! But 8 might make it a bit extreme. Your call on how many you would like. Cases and ODT's can be made to fit custom length.
* Entire Mark II assembly with 3 aluminum threads and Adapter ring - $109.00
(FilterSlide has 3 threaded and one open hole for unfiltered viewing)
* Additional filter slide - $45.00
* Additional rail set with adapter ring - $65.00
* Additional rail set for Denkmeier Bino(no adapter ring needed for UC scopes, $35.00) - $65.00
* Omega Dew Terminator(ODT) - $69.00
* Extension handle so you don't have to reach around on really big dobs - $10.00
**For each additional filter hole add $20.00 per hole per slide**For each accessory to accommodate the additional holes, add $20.00 per hole per accessory
Example: for an extra slide($45) +1 more hole($20) making it 5 holes(4 threaded)= $65.00
And for an ODT to accommodate the 5 hole slide(4 threaded) is $65 + $20 = $85.00
Darn, I hope that makes sense...
