Telescope Reviews: Re: Zoomin....

First Light!

Impressions:

An extremely versatile EP. Zooming to meet the seeing conditions is a big plus. ER not that bad, usable with specs, one has to turn their head ever so slightly to see the field stop. Without specs, no eye placement issues whatsoever. The entire FOV can be seen with the EP ~ .5 - 1mm away from the eye socket. The ever so easy eye placement and very usable ER for an EP with a FL between 6 and 3 is amazing to me, truly a marvel of engineering.

Onto the visual stuff:

Seeing, what seeing, all observations were made through either haze or thin cloud cover. Objects observed were the Luna and Jove. The Moon was comfortably bright at 6mm. progressively getting dimmer as you move towards 3mm. The thing that stood out in my mind was no loss of detail, dimmer but the sharpness and detail hung right in there. Jupiter was low ~ 20° or so mired in haze but the N and S equatorial belts were clearly seen as well as some smaller cloud detail at 3mm. For the seeing around 5mm was best, but the thing that really gets me is no matter how much mag. I threw at it the image remained sharp. There was some slight distension of the disk of Jupiter as the planet entered into the last 10% of FOV, but, the disk remained sharp. Did I mention the views were sharp?

I can't wait until truly clear skies for this EP. I'm sure things would have been ever sharper had the lil ole Pronto had time to warm up, there is about a 15° differential between the house and outside. I am also eager to try it on M13. The 3-6 Nagler zoom is clearly an optical wonder.
