the decrease was obvious. This technique is simpler and more accurate than trying to remember how large the field is supposed to be in these eyepieces as you're looking through the binoviewer in the telescope. (
unless it is a low power scanning eyepiece. It bugs some others. I also don’t seem to notice mild EOFB. Don is big on TV eyepieces so he has no issue with pincushion and didn’t evaluate it in his comparison of Morpheus and LHD. But it bugs some others, granted, usually more as...
A powerful and capable telescope, the Orion SkyQuest XT8 Classic Dobsonian is one of our most popular reflectors due to its elegant combination of precision optics, mechanical simplicity, and rock-solid stability. You and your whole family will appreciate the bright, clear views of the night sk...
(2002) with the MPFS integral field spectrograph at the SAO 6 m telescope. The field of view was 15″ × 16″, sampled by 1″ fibers, the spectral coverage ranged 6200–6900 Å, with a spectral sampling of 60 km/s. Based on its morphology (cf. Fig. 5) the authors interpret the...

I have read a lot of positive comments from recent Hubble Optics telescope buyers recently, from the photos they look to be better made than my early Hubble Optics dob I bought used, most negative reviews were of earlier models(older threads), one has to keep this in mind, also one shoul...
But the Meade 8.8 is similar price and features so that could make a good comparison when the weather cooperates. According to Ernest’s bench tests the Meade should win, but the Celestron should come close enough to make it interesting. Scott #73 Echolight James Webb Space Telescope ...
a little disappointed. More about why, but first let me say that I am sure many of you saw the review in SKY & Telescope of both the William Optics 7x50 and the Orion Resolux 10x50. While the 7x50's came out of the review with the impression that it had better optics than the 10...
