A superb tool in optical lens cleaning technology. Perfect for cleaning binocular lenses, small aperture spotting scopes and telescopes, eyepieces and other optical items.
The LensPen™ comes with a handy retractable dust removal brush and a special non-liquid cleaning element, designed to never dry out. Safe and very easy to use.
The Antlia ALP-T dual band 5nm filter is a dual line-pass filter which was designed to be used primarily with one-shot color (OSC) cameras such as DSLR's or astronomical OSC cameras. It can also be used as a narrowband filter for monochrome cameras to save imaging time. The advanced multi-coatings on our ALP-T ultra dual band filter effectively isolates the red Ha and the blue-green OIII lines light from emission nebulae, with almost total suppression of optical density (OD)4.5 on unwanted wavelengths from light pollution, moonlight, and airglow. The result is that our ALP-T dual band 5nm filter creates a superior signal-to-noise ratio and better contrast in your images.
The Sky-Watcher extension tube extends the height of EQ5/HEQ5/AZ-EQ5 mounts by about 16" so is a popular choice with owners of long-tube refractor telescopes as it places the eyepiece at a more comfortable height and prevents the telescope hitting a tripod leg.
Very nice look and good quality red dot finder. Easy to use with hex screws for perfect fine adjustment (very precise pointing).
Well machined and painted, comes with bracket and mount.
