LP filter, 1.25" or 2" ?

The very last thing you want to do is use a Barlow to make an already slow scope slower still.

2" T-adapters with threaded nosepieces are easy to find and pretty cheap. The best bet would be to get the reducer/flatner but that does cost a bit more.

Do not use the 200p 2" extension that came with your scope (as in the above photo). Look at the 2" barrel length.... its tiny!! I wouldnt hang a camera off that, they come loose really easily or never seem to sit square unless the grub screws are tightened up with pliers.

The best solution is either a 2" extension with a longer barrel (and safety undercut), or get a 2" Barlow, remove the lens element then pop your camera in that. You should be able to screw the 2" filter into where the lens element was (see below):
