Nothing would be done at all if one waited until they could do it so well that nobody could find fault with it.
Quote:I am always surprised at the concept that a 60mm scope is deemed a beginners scope, it is actually a tool only an experienced astronomer could "make work".
I think it is more a beginners trap (even one with superior optics). A 60mm f/11.7 with poor optics would be a beginner's nightmare.
Quote: But, the history of my desiring, acquiring and using telescopes began with this 60mm.The only caveat I suggest is you get a clear commitment concerning returning the scope for refund if the mount or the optics prove to be poor.Otto

Quote:While I agree that the ES 68s are probably a great choice (I have the ES 11mm 82 for my Dob) I'm sure she'll balk at the $100-$119 price each (especially for a $25 scope). Also, Agena has only two focal lengths in the 68s in stock (16mm and 24mm) so not much magnification to choose from at the moment.

Quote:Jon:I thoroughly enjoyed reading your reply and your enthusiasm is infectious You are totally correct, those 50's/60's and 70's 60mm f/12 - f/17 are definitely a cut above the 60mm offerings today (with possible exception of that ludicrously expensive Parks 60mm f/15 achro). There is something fascinating about these old 60 - 80mm achro's in various flavors - much has been written and said about the old skool Unitron's, Mayflower's, Vixen's, Jaegers and so on... Products where a lot of emphasis was placed on sound engineering and good objectives - it certainly feels that one is using a legitimate instrument versus a toy. Even Tasco, much derided today, offered pretty good gear way back then and these scopes are worth picking up at a flea market or thrift store. My own experience with a 60mm = more challenging than a dob commonly available for under $400. One really needs that trained eye to pick up detail with the 60mm. I agree that a good 60mm scope (actually even a relatively modestly made one) will show a plethora of objects and should, in principle, be perfectly acceptable for would be astronomers. However, crucially, as you suggested, one needs an imagination and appreciation for the aesthetics of the sky. Rather than looking at a faint smudge and thinking "the Andromeda galaxy looks bad", a person really appreciating the scope and the object under investigation would probably think "I cannot believe I am seeing an object so far away that when that photon of light left it, the earth was covered with towering and ferocious beasts". My wife thinks like that, and thus is never dissapointed in what a telescope offers, big or small. Always excited at every object uncovered - it is an absolute pleasure to observe with her. My brother popped his eye through my 60mm and his reaction was more along the lines of "this is boring, I can hardly see it, lets look through a bigger scope".You have a deep passion and interest in this hobby, I can easily envisage that if all you had was a pair of binoculars or an imitation scope of the one Galileo used, you would still be out there figuring things out and getting exited with every challenging object detected. However, when one has this passion in limited supply (a passion that can of course grow), a 60mm may be somewhat a disappointment. I personally view a 60mm scope as a perfectly viable instrument doing exactly what it is meant to be doing, challenging to use, perhaps yes (experience being a factor here), dissapointing, no.

Quote:The Agena Astro EWA will perform very well for you in the f11 scope, I have all 4 and like them a lot in my f10 SCT and f7.5 C80ED, but the 20mm suffers in my f5 dob as does the 15mm to a lesser extent. I also use my 32mm plossl all the time. Great views in slower scopes for a very modest investment.
Quote:Jon-Thanks for the keen insight. Will have to consider a better diagonal. Will a dielectric help here or just go with an erect image of better quality than the stock diagonal? Any particular brand I should consider that is in the budget-friendly range (around $50)? Seeing how the diagonal is probably never going to leave the focuser, perhaps I should invest a little more here?
Quote:One last thought.. this scope is a $30 scope.. It hardly makes sense to invest a lot into this scope, better to begin with a better scope. But it does make sense to buy accessories/eyepieces that might be used in the future with other scopes. Jon
