Model: bst_sg_3.2Part Number: SP10850
Features include two ED glass elements and fully multicoated edge-blackened optics for excellent colour, enhanced contrast, high light transmission and minimal ghosting.
The six-element / four-group design minimises field curvature for a nice flat field, even when used with telescope f-ratios as low as f5.
Modern twist-up eyecups, 16mm eye relief and 21mm diameter eye-lens makes them comfortable to use, even when wearing eyeglasses.
The tactile rubber grip and milled indentations make them easy to handle in the dark and the 1.25“ nosepiece includes a safety undercut so the eyepiece is less likely to slip out of the focuser. The 1.25” nosepiece is also threaded to accept 1.25“ astronomy filters.
Well matched to shorter focal length telescopes to deliver high power without the need for a barlow. Good wide field and generous eye relief make it easy to use. Excellent value.
Haven't had chance to look through eyepiece yet,looks very good,very made
Ordered and received within 48 hours in excellently secure packaging. Fairly terrible, cloudy weather since purchase (as usual!) but got a small window to use it on a low moon and was staggered by the views (375x in a 400x max scope). I cannot wait to get some proper Lunar viewing throughout the year and very pleasantly surprised as it was a punt due to the high mag on my scope.
This is a potent eyepiece, when used it the right circumstances. It gives fantastic close-ups of the lunar details, when circumstances permit. It's quite striking to see Mizar A and B through it, too!
Probably... BST (BarSTa) Starguider ED eyepieces are available under a number of brands but we source them with their original factory name.
Yes. Definitely :-)
