Thanks, Steve, that's given me more than one thing to think about.
You are right: the budget won't stretch to a Televue at the moment (around $180) but I am in fact trying to get an idea as to whether or not the Barlow is the right way to go.
With the two 1.25" plossls I presently own the barlow 2x will give me the equivalent of 7.5mm and 4.5mm eyepieces. A 3x would give me 5mm and 3mm - which might be a better bet. The latter could be a right pain when it comes to keeping the subject in the eyepiece but it could be handy on those rare occasions of perfect (?) seeing.
It's a right quandary I must admit and I guess most of you have pondered over similar situations in your observing lives, so in that respect I'm sorry (but most appreciative of your reply) for taking your time.
I'm tempted to buy a cheap unit, such as the one you mentioned, just to get an idea as to what I might gain from a decent Barlow. It might be a couple of months before I could afford to buy a quality unit as I'm in the process of researching a replacement for my current vehicular transport but think that I could outlay a few dollars prior to that investment in order to test the water.
Again, thanks, Steve.
