T A WOW Posted June 5, 2013 Share Posted June 5, 2013 Simply put, would these be any good for astronomy? http://www.opticron.co.uk/Pages/oregon_obs.html Looking to buy some bins, but confused at the choice. Link to comment Share on other sites More sharing options...
Brantuk Posted June 5, 2013 Share Posted June 5, 2013 I have the Celestron 15x70 one's which are a similar spec (Bak-4, FMC, Porroprisms) and they work very nicely on celestial objects. You'll see the 4 moons of Jupiter but no planetary detail, Moon craters will be crisp and clear, and globulars and open clusters will look beautiful (eg Pliades, Beehive etc - M13 a bit smudgey). Nebulea and Galaxies though will be just faint smudges - Orions sword is one of the brightest of these and there's little or no defineable shape at this low a magnification. There's no price indication on that advert but (as a guide) mine were £85 and I've seen other similar brands on special offer at £50 from time to time. Hope that helps Link to comment Share on other sites More sharing options...

Brantuk Posted June 5, 2013 Share Posted June 5, 2013 Sounds like a reasonable punt. Unless you get a duff pair (eg badly collimated) then you usually can't go wrong with them. See if you can get them on approval or with a 31 day exchange/refund warranty - just in case. Link to comment Share on other sites More sharing options...
Doc Posted June 5, 2013 Share Posted June 5, 2013 I would say they should be pretty good, but I would imagine they need to be tripod mounted. Link to comment Share on other sites More sharing options...
philjay Posted June 5, 2013 Share Posted June 5, 2013 They are quite big and together with the high 15 mag will require a tripod for any useful observations not unless you are one of them statue blokes who stand around for hours in market places:-) Link to comment Share on other sites More sharing options...
T A WOW Posted June 5, 2013 Author Share Posted June 5, 2013 Bought them. The tripod they had were about another £150 so I'll leave it for now. Quite happy with these. I'll try them out tonight. 5th night in a row with clear skies Link to comment Share on other sites More sharing options...
Brantuk Posted June 5, 2013 Share Posted June 5, 2013 I put mine on a standard camera tripod (second hand £23) with an alt/az fine tuning head. Takes a short while to calm vibrations down but fine for the amount of binocular viewing I do. Link to comment Share on other sites More sharing options...
catman161 Posted June 5, 2013 Share Posted June 5, 2013 You could turn a broom upside down to steady the views in the meantime Link to comment Share on other sites More sharing options...
BAZ Posted June 5, 2013 Share Posted June 5, 2013 Nice Bino's. I like my 15x70's (Revelation), clusters really pop out. M44 is gorgeous. Get a reclining sun lounger, that should help. Link to comment Share on other sites More sharing options...
