2 inches filter into 1.25 ~ 2 inches adaptor

[LunaSwift]

I have got filter threads in the nosepiece of my 2" diagonal, I just screw the 2" filter in there, Guaranteed not to get hit by any eyepiece.

Thanks for sharing the picture of the various adaptor.

I see the adaptor to the right from your last picture, is it the same one has the previous picture with the Luminos EP ? but with some kind of 1.25 extension?  (Theoretically I could unscrew this 1.25 extension and put a 2 inches filter there instead?)

The Baader extension is quite expensive, almost 80$ with taxes and shipping, it's affecting my motivation...

This is a Baader VIP barlow - highly recommended. It has the EP adapter and is an astronomers "lego set". The optics are top tier as well. Yes this is the one in the other pictures.

Awo ok I get it,

Yeah truly it's a nice piece of equipment. The previous link I had was the top part only, T2-15. I would take only the top part really, I don't see the benefit of buying the entire assembly.

I have to decide if I want to spend 350$ on that filter project, not knowing if I will be able to focus all my 1.25 inches EP.

I refer you to the last sentence in your signature

LOL  

Put the project on hold again seems to be the very best solution.

I agree ithat t's right strategy to take a step back in step to pounder over choices than rush into one.

Here's what I see the pro and cons of Baader VIP barlow:

Pros:

1. excellent barlow, it sharpens on axis view of good eyepieces like Leica zoom and docter 12.5

2. very modulous: you can get 1.5x, 1.75x and 2x with easy, and you can do the combinations in many different ways, an adult legoland, i.e.

3. You get a component that you can use as extension for focuser or filter (the top part #T5-15)

4. You get a connecting part (#29) for mount a T2 part o n diagonal's nosepiece (a GPC for binoviewer e.g).

Cons:

1. Cost

2. Balky, bigger than many simpler 2x barlows.

 

So, take your time, and think it over throughly.

It's a nice Barlow, I have to admit it looks like great engineering.
