Dob filter wheel

[jetstream]

Does anyone use a filter wheel with a dob?If so which make/model?

By coincidence, I have just bought one second hand for use on my dobs. It's an opticstar moden but I think they are all pretty similar. http://www.opticstar.com/Run/Astronomy/Astro-Accessories-Imagers-Opticstar.asp?p=0_10_5_0_3_300

not got /used it yet though.

Thanks for the link Shane,it looks good.I wonder what total height the unit gives,with the supplied adapters?It will sure be nice to have one all set up to observe nebulae etc,less monkeyin' around

That's the thinking for me too. It's mainly for colour filters as I want to try them but messing about keep changing them is asking for trouble in the dark.

One advantage of the OOUK scopes for us is that there seems to be about 50mm of extension required to get focus and I for one use an extension to do so. therefore the focus position should not be a problem (in theory at least). e.g. for now I pull out my Paracorr by about 30mm to achieve focus. with this in place I suspect that I won't need to. then again it might possibly affect the normal paracorr position of course.

Just wondering if anyone has had success using the Baader Q turret with the Skyliner 200p. it appears that it allows a filter to be put on the nose piece, so you can swap eyepieces without having also to move the filter between them.

you can also do this with a 1.25"-2" adapter.

I've been thinking about one of these Gerry.

They get some good reviews. Although not strictly a wheel

Wouldn't the filters get dew on them?

I use a filter wheel although I don't use it for my dob, so much easier than filling about with filters/cases in the dark!

Ahhh I should of looked at it properly, didn't see its got a Dew Terminator!

Looks a very nice bit of kit then.

If you look down the page mike they do a dew heater kit for it. Probably be just as easy to give em a blast with the old 12v hair dryer though.
