BS Astro manual filter wheel

[adamsp123]

I decided to get the BS astro 2" filter wheel from Modern Astronomy as the cost of a USB version plus the 2" filters was just too expensive.

The wheel is very sturdy and well made, 4 allen key type screws hold the 2 plates together, removing these you get to the wheel itself for placement of the filters.

The click stop for each position is very positive with a little window where you can see a number (1 to4) corresponding to which filter is selected.

I have not noticed any light leakage when in use and I do have some stray light coming from neighbours outdoor lamps from time to time.

As it is all made of Aluminium I would recommend careful and light lubrication of all the treads of the filter wheel, the camera locking ring and T adaptor are hard to unscrew without an application of lube, I used a small drop of light 3 in 1 oil.

Very happy with the product.

A manual wheel will be what I get so good to read

Like the look / sound of that.

Anyone know if it's 1.25" sibling can accept the cheaper Baader LRGB filters?

RGB Filters & Filter Sets - Baader RGB Filter Set with IR Cut

Thinking of having a go at colour video myself...

Yes it can. I had some Baader filters in it and Orion LRGB which are also high.

Excellent. Just what I wanted to know.

Ah, here it is, with experimental 2x wheel setup (+ AE wheel that doesn't have T-threads):

Note: if you want to screw something into the T-thread from the filters side that isn't part of the wheel (wheel nosepiece or T-ring) it has to have short T-thread or it will hit the Baader/other high filters. For Celestron Radial Guider I have to reverse the filter so it screws into the OAG and filters aren't blocked

Heheh - Like that setup. Filters / Wheel on order.

Aside: Good website too - With lots of interesting topics. Was thinking about "messing about" with spectra. Threw in a "Star Analyser 199" too. Thanks for (generously) sharing your ideas.

The only problem with BS wheel is with Lumicon filters. They are just a little thicker and block the wheel from turning. Need a simple flange from plastic, around the wheel, and works fine!
