Ethos price announced

Here is the place to talk about all those equipment(Telescope, Mounts, Eyepieces, etc...) you have. Not sure which scope/eyepiece is best for you? Trash it out here!

Favourite scope: Mag1 Instruments 12.5" Portaball

Its good to clarify that UWANS and Meade 5ks are not clones of Naglers in the sense of exact engineering copies of the Naglers... No point getting into legal trouble here, and not all are familiar with the myriad of eyepieces out there. Furthermore, these companies are doing a good job providing us with alternatives so let's not tarnish their reputation :)

Anyway, I like the "clones" as they have performance comparable to the Naglers for a much lesser price. YMMV :)

cheers

Hmm... Ethos clone... wonder what it will be called? Sohte? :mrgreen:

I was just saying that Singapore's sky condition is good enough to tell that 10 percent difference in performance. I gave an example of an average seeing condition that allows 0.8 arc second separation. In good conditions it probably can go till maybe 0.3 to 0.4 arc second which is the resolution of a 12.5" scope.
Hmm... I don't think able to resolved 0.8 arcsec are call average seeing... unless you are on Mauna Kea observatories :P . Also, base on W. M. Keck Observatory website: "Without any correcting technology, the best telescopes on Earth are limited to an average “seeing” ability, or resolving power, of about 0.5 arcseconds":

Anyone get one please post a review!!
There already a review on cloudynight: http://www.cloudynights.com/item.php?item_id=1619

Have a nice day.
I said average seeing conditions because it was very windy with clouds flying about very quickly that night. I seriously doubt there is good seeing then but I could clearly see a 0.8" double star separation at 220x. What the astronomers are saying is mainly average as in over time (maybe the whole night average). The sky momentary can have very good seeing conditions for a few seconds and that is why big scopes have an advantage over small scope where faint details can be seen for that few seconds. Well these big observatories are not meant for visual.
