Thanks @wrvond, @jon isaacs, and @aeajr for all of your help. I have a little work ahead of me cleaning up this scope and primary mirror and then deciding on what eyepieces. I appreciate all the input and links you have provided.


Hugh:

Did it come with any eyepiece's?

Plossls are very good eyepiece's and are very affordable. They are sharp in the center and quite sharp across the field at F/8. The ~52 degree AFoV is reasonable. The eye relief is reasonable in the longer focal lengths, under maybe 10 mm, you'll be close to eyepiece.

A good Plossl is around $30-$40.

From there.. wider fields of views, sharper at the edge in F/5 and under scopes, more eye relief in the shorter focal length.. one can spend $600 or more.. on one eyepiece..

With your 6 inch F/8.. Plossls and the like will do a very good job, that's one of the reasons a 6 inch F/8 Dob is considered a very good first scope.

Jon,

It only came with one eyepiece and I think it's 24mm or somewhere around there. I'm looking into the eyepiece part right now and one that I'm considering is the Astro-tech Paradigm ED pieces. https://www.astronom...pieces_c52.aspx

Would you recommend a Plossl over the Paradigm?

Hugh:

No, I'd prefer the Paradigm. More eye relief, a wider field of view and still very affordable.

My main eyepiece set is basically all Tele Vue eyepieces with 68 or 82 degree field of view. But I also have a set of TMB Planetary eyepieces which have 60 degree AFoVs and about 12 mm of eye relief, very similar to the Paradigms.

I use them a lot and while they don't have the widest field of view, it feels wide enough to me and the eye relief is comfortable.

What focal length(s) are you considering?

Jon

Is this a push-to scope, meaning it does not use motors to automatically track objects?
If so, the extra field of view offered by an 82 degree eyepiece vs a 50 degree eyepiece, for example, would be a welcome plus.
I enjoy my Dob, but without my wide field eyepieces (about 70 degrees), it would be bothersome. Just my thoughts.

I'm considering the 8mm and 12mm.

Is there another eyepiece in the same price range of $50-75 that you would recommend over the Paradigm? I'm the type person who typically buys mid to upper end gear and I'm purposefully holding back on this new hobby since it can apparently eat up a bunch of money pretty fast. Plus, this is a 10 year old scope with a 1.25" focuser and if I end up eventually getting a bigger scope it might have a 2" focuser, which would need different EPs.

Thanks, Jason. What about the Meade 5000 ultra wide angle series? https://www.astronom...ice_p19428.aspx

Are there others in the $100+/- range you would reccomend? I like how I just stated in my previous post that I'm trying to stay in the $75 range and now I've bumped it up for the wide angle EP. This could be a slippery slope.
