Thanks for the replies
I do get quite bad star bloat in the blue on my 72ed. So just looking at a refractor which doesn’t have star bloat. From what I have read, triplets have very good overall performance over UV to IR
i do like the WO looks more we’ll built then the skywatcher, but it does look like I also need to get the WO flattener/focal reducer as the skywatcher comes with one.
As for the other refractors with different glass that they claim are the same as FPL 53. I’m hesitant about the claim as trying to get information about the transmission response is almost impossible to find. As for FLP glass you can find it quite easy. From telescopes with the different glass I find I get better images with my 72ed apart from the star bloat, bit it could be the image processing.
I do have a auto focuser which I will connect, so I guess it’s pretty straight forward, just remove the fine focus knob and attach the focuser.
