Solidly in the mid-magnification range for most amateur telescopes, the 25mm is a true workhorse for visual observers. If you love deep sky observing, eyepieces in this focal length range not only give healthy increases in magnification, but the contrast enhancement of giving a darker background sky can make all the difference of how galaxies…
Mid-range high power eyepieces like the 10mm are instrumental when transitioning through magnifications to observe an object until it is best seen. There are several aspects that have to come together when observing at high powers: good-to-perfect atmospheric seeing conditions telescope optics that are collimated a telescope that is acclimated to the ambient temperature brightness…
Explore Scientific Filter Set N3 is recommended for lunar and planetary observations through telescopes with an aperture of 150mm (6′) and higher.
Prepared slides are ready made conserved preparations. For high contrast the most of them are stained.
Permanent preparations are ready made conserved preparations. For high contrast the most of them are stained.
