Televue (maybe Powermate), or Revelation Barlows

[Fordos Moon]

After a bit of advice on Barlows please.

Thinking of getting one to replace the Skywatcher 2x I have which is "okay" but I wonder if I can get better?

I have got a fairly decent image of Saturn and Jupiter with it, using an Xbox cam.

Was lucky enough to receive an ASI120MM for Christmas (am over the moon) which I will be using for guiding with my ED80/ST80 but want to try a bit of planetary with it with my 200P (as I did the Xbox cam).

Looking at 2nd hand barlows I wonder which one to get to assist at all with this set up. Lots of different ones out there.

Any advice please for use with 200P?

Thanks, Bob

I can't compare them but I do have a Revelation 2.5x which gives very good results and also has good reviews all over the place.

I may be wrong but for planetary imaging I think that after aperture, focal length is what counts. therefore stacking both the current barlow and a 2x or 2.5x barlow might be a good thing. otherwise, maybe a 5x powermate? the imagers can possibly provide more info in this?
