Looking over the prices.

The Orion filter wheel from Bintel is $275 + 10 P&H = $285.

The Orion filter wheel from Telescope.com is $143 US not including P&H = $190 - $200.

A big difference. eyy...

With the filters..... Well I have to have a look.

Is there any difference between 1.25" filters and 2" filters?

Is it true that the 2" filters let more light through than the 1.25" filters.

Yes well it's up to you where you get it from, I'm just answering you question about Aussie suppliers for filter wheels.
I know they're not the Atik brand but they're similar I suppose.
Unless there's a cheaper Aussie supplier for these things.

All I know is I really like the Orion F.W.
I haven't used one but it looks and feels nice.

I'd say the 'using' of one would serve one well in an appraisal?

But how can you go wrong for the money.

I'm still holding out for the Atik, though.

If I can't get one in the next few weeks I may give the UK brand a try, or even spend a few more $$$ and opt for a True Tech

maybe for DSO's ( i am not sure), but for most planetary, you stick to 1.25" powermates, adapters, opening on the camera etc.

when you think of the size of a planet with lotsa black around it on a ccd chip, 2" would make not difference at all.

I've found a 1.25" Lumicon Filter Selector. It has 5 slots for filters except it doesn't have an enclosure. I can get it for $180 including P&H. It looks pretty good.

How do filter wheels compare to filter selectors?

Believe it or not that is pretty identical to the slider as used by world's best planetary imager Damian Peach.

(At least, that's what he was using almost 12 months ago when imaging from his own backyard).

It obviously offers almost no protection for your filters against dew or dust...but will definitely get the job done.

I didn't like the idea of expensive filters being exposed to dust, dew and finger prints in the dark so I got rid of the Meade slider and bought an enclosed wheel. The slider is probably a cheaper option but you pay for what you get.

Very true.

With expensive filters you need a way to protect them.

Would it be worth to buy from overseas to save a few dollars?

Matt,

When I was faced with the same decision I came to the conclusion that the wheel was cheaper sourced from UK (with the benefit of strong AUS dollar) but I bought the Baader filters locally. I guess you need to do the sums with the current forex rates. Good luck!!

If you are interested in the Astronomik filters for imaging, as you should be, you'll save a fair bit of money by buying overseas

I agree. Adirondak was the best price I could find for these.

I got mine for $260US from Oceanside Pacific Telescope (OPT).

It worked out to about $300 AUS which compared very favourably to the $400 being asked domestically.
