Bugger,
Here I was thinking about a 6mm TMB for my F6 dob to do star testing/collimation with and someone helps out with "a weakest in the line up" comment. (helpful yes...) TMB II's are currently going for under $40 AUD with free postage at aliexpress(The Outdoor Movement Store) - I'm hoping for Chinese New Year specials - But the APM 30mm UFF is not budging atm...
Any pro's or con's about using a eyepiece/barlow combo to collimate against star tests? (like adding extra plumbing from a cheap barlow is not the best idea?)
Well, I'm still on a high as I have found someone to try and get my 8" glass blanks cut with at less than half the price of other quotes. Just dropped of the slab of glass half an hour ago. Fingers are crossed they don't shatter under the water jet.
Steve
