Quark's BF on Lunt diagonal

Daystar's bf is about twice the size of Lunt's in my BF600 diagonal, I briefly swapped them. The picture is awful, with Quark's bf in place of Lunt's little red glass. Double limb and barely any h-alpha details visible. What's strange, is that in Quark bf placed with the mirror side forward, in Bf60...

Re: Need a full disc HA sidekick (PST/Quark/??)

My Quarks barlow was easy to remove, without damaging anything. You can screw on the Powermate 2x, instead and upgrade the blocking filter to 25mm from Andover . The native bf filter is Andover's 12.5mm. As for the F/30 focal ratio, it's probably overrated, Daystar claims similar performance from 15...

25mm filter sounds tempting, but, I'm strictly visual and don't do imaging, so not sure, if it is worth spending extra on it, or is it?
Can Quark's own BF filter be reused with the x4 Powermate, if so, will it require an adapter?

Re: Lunt50+Daystar Quark as doublestack?

Thanks man, I will think about ordering a 40mm piece as well.
Was under the impression, since F/5 has a smaller magnification factor, 32mm should work similar to 40mm on the slower refractors.
Have you tried stopping your scope down, to say 70-80mm, to get closer to the recommended F/30?

Barlow is 2x, I presume then?

Then, it looks like the 75x250 convex lens matches Lunt's 50 F/7 even closer (assuming the fact the same barlow is used in both).
Would be curious to know, if the 50's tube internal diameter is sufficient to be used with the 70mm objective.
