Hello from Milford Massachusetts!
No more messing with trying to screw those expensive filters onto your eye pieces in the dark.
1) The "Original" FilterSlide
2) The Mark II
3) A Customized Assembly
*Each with Multiple Options*
This design is intended to be used in conjunction with the Feather Touch Focuser made by Starlight Instruments via an adapter ring, made by them specifically for my FilterSlide assembly. As you can see in the pictures below, the adapter ring threads into the nose of the focuser tube.
My "Original" version is used on any Dobsonian scope with a focuser other than a Feather Touch. This version is designed so the customer will mount the rails to the UTA via 4 wood screws. Instructions are included.
Specifically designed for the Astrocrumb FilterSlide.
Custom made fore each slide, No matter what length or
number of extra holes.
To be used in conjunction with standard dew controllers.
(Like the Kendrick, Thousand Oaks or Astro-Cube)
It's a good idea to protect your investment in filters! I've designed this case for convenience in the dark and to stand up to the abuse in your accessories case. Birch wood. Ipswitch pine stain. Satin varnish. I am also offering custom cases that will hold 2 or more FilterSlides. It is simply the same design, just stacked together.
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 - $135.00
(3 threaded holes plus 1 open hole for unfiltered viewing)
* Additional filter slide - $65.00
* Additional rail set with adapter ring - $75.00
* Omega Dew Terminator(ODT) - $79.00
* Extension handle so you don't have to reach around on really big dobs - $15.00
For my "ORIGIANL' version price is $89.00
**For each additional filter hole add $25.00 per hole per slide
**For each accessory to accommodate the additional holes, add $25.00 per hole per accessory including birch cases
Example: for an extra slide($65) +1 more hole($25) making it
5 holes(4 threaded)= $90.00
And for an ODT to accommodate the 5 hole slide(4 threaded) is $79 + $25 = $104.00
Darn, I hope that makes sense...
As every order requires me to confirm compatibility, please email me with all inquiries! Initially, I will need to know the brand and aperture of your scope and the brand of focuser.
Bracketed for a particularly tricky UC
As seen above, I can make custom FilterSlides with more holes!
While there isn't much affect whist actually observing, the intrusion into the light path can be minimized what extra attention to the mounting.
Yup, working hard!
If preferred, I can take checks also!
I'll provide my address, if needed.
It was driving me crazy dealing with screwing in those 2" filters every time I wanted to try a different view. So for that reason(and I needed a way to finance a full set of Naglers...), I came up with the Astrocrumb FilterSlide.
Basically, I produce the Astrocrumb FilterSlide in my workshop, from scratch. There are 2 parts I have help with. The adapter ring for the Mark II that threads onto the Feather Touch Focuser, made exclusively for me by Starlight Instruments. And the threaded aluminum rings produces by DVF corporation.
Producing each FilterSlide is pretty much custom and on demand as there are just too many scopes out there with different idiosyncrasies. So my turnaround times will vary depending my workload.
Thanks for your interest in my FilterSlide!
