Bought a Bluesky BT600 for about 50 bucks. This is how it looks like: http://www.mercadolivre.com.br/org-img/original/MLB/092004/21201258_499.jpg Anyway, this is what it says on it: 56x525x /60mm As well, it came with a number of parts, I'm gonna list them here: * an eyepiece that doesn't say much and which fits: - a H20mm thingie - an SR4mm thingie - an H12.5mm thingie * 1 . 5x erecting eyepiece * barlow lens x3 Now what do I do with them, how do I use them, etc? Any sort of help would be much appreciated. Thanks, Drac
