I don't know if anyone has attempted that. But ASA has a pier/mount with a dual RC rig.

When combining a reflector and a refractor, and collecting lrgb data, I would use the system with best pixel scale for L, regardless of scope type. But if pixel scale is about the same, using the refractor for L will probably result in tighter stars. If the spikes are in the colour data, then lrgb combination will remove them, because spikes are related to intensity (L) more than to colour.

That price is actually only for the pier and mount - you have to buy the scopes separately as far as I understand. But I see that it comes with adjustment plates which is good!

Thanks Richard! Buying an Esprit 100 can never go wrong. What camera are you longing for?

I'm cosidering this in osc as i can't stand the reflections my 071 produces with the Epsilon.

Well, I can find out using the spectrophotometer I have at work to check the transmittance spectrum of the Baader filter. If it is much wider than 3.5 nm I guess I could complain.

Oh, yes please.?

A very interesting camera Richard. Go for it and show us what it can do!

Thanks a lot Mike! Much appreciated, especially right now when no clear skies are forecasted up here

Do you really need that though? It seems your fov is much smaller on the 150 scope, so there is a margin for inaccuracy..

I am asking beceause I am considering going dual rig, as I now have a 130PDS and a 80ED.

Come to think of it, reflector + refractor might not even work..?

No it wont work unless you want weird diffraction spike color and halos.

Personally I would not consider a duel 130PDS setup either as the diffraction spikes are hard to align and the alignment of the FOV will change with changes in colimation.

Not impossible just really painful.

Yeah that sounds very troublesome, and not something I would even consider without a permanent setup.

But someone is going for it

Dual Takahashi Epsilon 130d.. Not bad..

One solution is of course that you start saving up for another refractor or a spikeless reflector such as the SW MN190!
