Acquired a new Barlow for my planetary imaging endeavours. Decided on the Baader Q-Barlow 1.25” 1.3x/2.25x because of its modularity and that the Barlow element can be screwed directly into an eyepiece of in my case a T-Piece.
In practice, the Barlow Element is screwed directly into the T-Piece, the IR filter is screwed onto M42 side. The whole assembly is screw on to the ASI224MC which makes for a neat compact package.
I have estimated the assembled parts gives me a F/Ratio of 18 which is close to the 5 times rule which I have read about.
I got to test it out to night, so in practice it works a treat, here is an image of Aristoteles.
Cheers
Anthony

Is that a little violet fringing I can see? It's a kinda cool look and makes it resemble the view one would get through a big ass old refractor at a famous city observatory, in good seeing
Ah, 12 inches, that's why I can see the dinosaurs footprints. I hear an asteroid made them extinct?
With a 14" scope you'd probably see the skeletons too.
I play with nothing over 8 inches and I'm not trying to boast, I'm talking about telescopes. I did try to see the moon through my rc8 with the 5 times powermate, think I expected a bit much and couldn't achieve focus on a night of bad seeing.
With the RC8 I never remember whether it's adapters (spacers) on for visual or photography, two x 1" spacers and one 2" spacer but I keep forgetting what suits what.
Continual rain and cloud since I purchased it hasn't helped nor has the fact I haven't put my pier in yet (no observatory unfortunately on rental property). I do however have a big hole (600x600x600 (and a bit)) in the back yard full of water and I'm thinking of drilling holes in the bottom to drain it.
