What is the best order to fit accessories together?

[Stub Mandrel]

I have the following to fit to my 150PL for planetary imaging this summer:

5 position filter wheel

Atmospheric Dispersion Corrector

x3 Barlow (can either be fitted to a 1.25"barrel or to an normal 1.25" filter thread)

The ADC and barlow have male t-threads as well as a 1.25" bore.

The filter wheel has 1.25"/t-thread adaptors, as does the scope

I can probably fit the three accessories together in any order, but what is the BEST order? or at least what factors should I take into account?

I guess the barlow should probably be closest to the camera - or should it be the ADC?

Barlow in the eyepiece holder

Filter wheel as close to camera as possible.

Do you need to use the ADC if you are imaging through filters?  Just a query as I was under the impression the ADC improves the difference in focal lengths between red and blue light at low altitudes. Might be completely misguded there  But if it is that, and you are imaging separate RGB channels, my thinking would be you wouldn't need the ADC also.

My understanding is it still improves the image as the filters are wide band - certainly with one shot colour the green, especially, suffered from bad dispersion.

I also want to image LUM though a baader uv/IR cut.

ah ok, OSC cameras plus filters are a whole different story, in effect two sets of filters working together or against each other. My gut feeling would be ADC first, but im rubbish at planetary imaging

Good luck!
