Hi Peter
I'll chime in with my own personal experience of what works best for me. Others will hopefully add their opinions too.
I have a 10" dob as well. I am also short sighted & don't need glasses for eyepiece viewing. I had a heck of a time with the 9x50 finder that came with the scope- I could never see a great deal thru it & I couldn't contort my body & neck in the positions I needed to, to see anything useful of it.
Plus, I had trouble finding a particular star in the sky thru it (too many teeny stars in the finder).
So off it came and I replaced it with a red dot finder (RDF). The one that's a square glass window. I find that easier to look thru than the long tube ones. At zero magnification (like the Telrad) it was easy to point the scope on a certain star in the sky. I never looked back.
Then, that wasn't enough. I kept the RDF but I needed something to help me find targets.
So I bought a Telrad. Most people praise them highly. Me, I struggled and I could never get objects with it. And it dewed up too easily rendering it useless. I could've spent a lot of money buying dew equipment to counter act this but I didn't want to. I also found the circles distracting.
I got rid of it.
I then added a
Stellarview finder next to my RDF by drilling extra holes (hubby did all the work not me lol) for it. They sit snuggly next to each other so it's as much in the middle as possible- the finder is in the middle with the RDF just off middle. And I've never looked back!
The Stellarview finder is a dream to use. The right angle holder (R/A) on it means that you can position its eyepiece where ever you want it (it swings). You can also adjust focus to suit your eyes. And you can easily swap eyepieces on it (it already comes with an eyepiece which is the best one to use with it & it has a lovely large field of view). So now, I find the star with my RDF and I star hop from there using the finder.
The Stellarview is a top quality telescope in its own right. I bought the tripod adaptor and I just slide it off the dovetail from my scope and sometimes use it on my tripod- little grab'n'go scope!
I decided to go for the 9x50 rather than the 10x60 so I keep a nice widefield view to help find things. I think you will be impressed in how well this is made and how it performs. When observing thru my scope, I spend just as much time enjoying the views thru this finder.
I've since added an Argo Narvis push-to-go and here too I find the RDF is so handy for doing the two star alignments on it and when it takes me to an object, I look thru the RDF to see where it is in the sky.
If you'd like a pic of how both the RDF & Stellarview finder sits on my 10" dob, let me know and I'll happy to take a pic and post it here. Meanwhile, here is a pic of it on my tripod.
If you're interested in purchasing one, fellow forum member Peter Read of SDM sells them. And he's in Melbourne where you are! Even if you weren't, he'd post anyway. I bought mine from him and he was such a pleasure to deal with and so helpful. He also told me exactly what I needed to buy with it to mount it on the scope (I found the Stellarview webpage too confusing with all its accessories for it!). The mount he chose for me is perfect as he said the one he recommended for me works the best on my dob). If the mount is too high, you have to stretch too high to see thru it.
