Better planetary imaging scope?

[GazOC]

I know this sounds lazy, but I'm not in the mood to set the two scopes up and get an answer myself. So here goes...

Do you reckon I'd get images any better using my 150mm f8 (1200mm) refractor and MV filter with 4x Barlow than my 150 f 12 Mak (1800) and 2x barlow?

I ask because setting the frac up stops me using my Newt at the same time whereas I can set my Mak up and the Newt at the same time.

The frac would give you the image @ F32ish

The mak would give the image @ F24ish

for planetary images i would say F32 would be the prefered F ratio.

[Rob]

I would have thought the Mak?

[Jamie]

Rob i know that Maks are great planetary scopes but for

planetary imaging its important to get the F ratio up around

F 30 - 40 for the best results.

Then again if your frac is not up to the job the Mak will have to do i suppose

Hard life eh? I'll post the results later....

Nice problem to have eh mate? (two scopes dunno what one is best)

I know which one gives the best views, unfortuneatly it's not the one thats easiest to set up.

So which one gives the best views? I'm interested now as i can't seem to get my Mak. to do imaging. Visually it rocks, but stick a webcam up it and it sulks for some reason. The Newt. loves imaging but the images are smaller than I'd like and it's a marginally bigger setting up job. If I can't get the OMC140 to image, I think I'll get shut as my skies only allow imaging due to LP.

The refractor gives the better planetary views by far if you don't mind the CA. Where the Mak "wins" is that it takes a EQ6 to mount a 6" refractor but only a EQ3/2 for a 6" Mak.

I think a fairer comparision would be a 5"-6" Mak against an ED100, similar cost and similar mounts required.

[Kaptain Klevtsov]

I'll give my 'frac a bash at it tomorrow night if the clouds are in bed. If the 'frac does the business I think the Mak is up for sale.

Last year I did some imaging through my Mak (Mars) + Orion 2x shorty barlow. That seemed fine. Focusing was a little hard though.
