Hello. I have been enjoying my NexStar 6SE for a bit now (definitely kept me entertained during lockdown), and I was just had a question about the diagonal or diagonal upgrades.
For context, I mainly do planetary viewing and some DSO observation (mainly nebulae), so my goal would be to possibly try and increase the viewing experience and possibly the contrast. I have been using the standard 25mm PLOSSL, a Baader IV Hyperion Zoom (oh my I love this eyepiece) and a Celestron OMNI 32mm eyepiece.I was looking at upgrading the stock prism diagonal (#94115-A), so I tried to do a bit of research, and it seems that a lot of people recommend the Baader T-2 prism star diagonal pieces ( but I'm interested in this one in particular https://www.highpoin...e-holder-prism1
I'm not too worried about the cost, but I was just wondering if this is worth the upgrade over the standard prism diagonal or if someone can offer some more information/point me in the right direction?
Oh, on a side note how do I go about cleaning a prism diagonal? I have a fingerprint on the inside where you slot an eyepiece in that's been there for a while, doesn't seem to impair the viewing experience but would be nice to not cringe whenever I see it.
