Get a quality workout with our heart rate monitor. When worn
around your chest during an activity, it wirelessly transmits your
heart rate to your compatible device for instant feedback on how
hard you’re working.
The front part of the strap contains the heart rate module and
is made of flexible plastic. The part of the strap that goes around
your back is made of a soft fabric and is adjustable to your
size.
Use and care of the heart rate monitor is a snap. Once it's
paired with your compatible device the first time, it will
automatically recognize it each time. The fabric of the strap can
be removed and hand-washed as often as needed.
Highlight of the newAntlia LRGB V PRO 31mm, Unmounted
Improved contrast, star hypertrophy, and halo minimization compared with the previous Antlia LRGB V-series
Premium coating technology and finely polished substrate Our quality selection processes are optimized to ensure highly homogeneous glass-substrates. Our application of advanced optical coating technology and double-sided precision polishing achieves both consistent parfocal and optical performance across all filters.
Maximized colour balance and contrast for each of the three RGB channels and excellent S/N performance Dozens of coating layers are deposited on both sides of the glass substrate that enables LRGB-V Pro filters to achieve a high SNR. The Anti reflection coatings and carefully designed spectral gaps minimize unwanted light scatter and maximize useful signal data for each filter channel.
Tighter star profiles and halo reduction The cut-off rate of LRGB-V Pro series set is designed in high level to minimize halos around brighter stars and reduce star bloat. Our careful design of the blue channel transmission characteristics targets the problem of blue star bloating.
ตัวแปลง SVBONY Prime Focus + Variable Eyepiece Projection Camera adapter, 1.25"
Composed of two detachable parts: a prime-focus adapter for prime-focus photography, and a fixed-length or variable extension tube for eyepiece-projection photography.
Supports maximum of 46mm eyepiece diameter
Connects with SLR & DSLR Camera for Eyepiece Projection Photography
Has a handy laser engraved Extension Scale
The 1.25-inch Extendable camera adapter is made of black anodized aluminum and is suitable for all standard 1.25" astronomical telescopes
Easy to connect camera body (needs T-Ring) to a reflector or refractor telescope for either prime-focus or eyepiece-projection photography.
Can install filter (pipe thread) and compatible with the 1.25-inch eyepiece.
A thumbscrew in the extension tube holds the telescope eyepiece in place. This combination of prime-focus and eyepiece-projection camera adapter has a sliding barrel design that allows variable projection distances.
Built-in protective pressure ring to prevent eyepiece barrel from being scratched.
The L-Ultimate is a 3nm dual band filter designed to drastically reduce the effect of light pollution. The 3nm isolates the nebulae's emissions into H-Alpha (red) and OIII (green-blue). It blocks light pollution, maximizes the signal from nebulae, and darkens the sky background. It also blocks artificial light from mercury vapor lamps, high and low pressure sodium vapor lights, and unwanted natural light caused by the emission of neutral oxygen in our atmosphere, maximizing the transmission of the main emission lines of the nebula in OIII (496nm and 500nm) and H-alpha (656nm). Used with DSLR, color/MONO CMOS and CCD, this filter is suitable for telescopes with an f-ratio of f/4 or higher (slower).
I took this Telescope because the 10 inch GSO Dobsonian was sold out. After building a Rocker Box myself, i tried it yesterday and i am very happy with it. The shipping was super fast,- all perfect.
