Altair Astro

The Altair M48 tilt adjuster is designed to give the perfect image field by making the CCD or DSLR camera sensor completely orthogonal to the telescope's optical axis.

Why choose a SkyTech DSLR Clip-Filter?

• It can be inserted or removed in seconds.
• All lens functions (focus, preview screen, image stabilization) work as usual.
• If you have a telescope with short space between reducer/flattener and camera and filter wheel, or a camera lens, a clip filter is the solution.
• It protects your sensor from dust build-up during long exposures when the mirror is up.

• Clear bright and sharp image from horizon to horizon for your Allsky Camera.
• Capture meteors, aurora, space stations and satellites over the entire sky.
• 1/2" camera chip will give you a full 180 degree plus image circle.
• 1/3" chip will have slightly clipped top and bottom edges.
• Fits Altair, ZWO, QHY and other Allsky CMOS cameras.
• Colour or mono NIR corrected.

The new TriBand V2 Filter

• Anti-Halo coating on both surfaces to reduce reflection artefacts from reducers and camera lenses.
• Increased blocking of UV, IR and unwanted visual range wavelengths. UV OD7 (T0.00001%) Visual OD5 (T0.001%) and IR OD4 (T0.01%) for the ultimate in skyglow blocking. This is an order of magnitude better than foreign filters.
• Higher transmission % of desired wavelengths Ttop 93% (Average 5% higher transmission of target wavelengths than V1). In general a 5% gain on foreign filters.
• Ha at 14nm and Oiii at 34nm FWHM for with less tail-off to reduce unwanted light pollution, whilst keeping transmission high compared to the V1.

High quality filter for CMOS photography with the following features:

• 1st band, CWL495nm FWHM35nm
• 2nd band, CWL 660nm FWHM 35nm
• 1mm thick optical glass with 30 arc sec parallelism.
• UVIR Block and Anti-Reflection Coating.

With the TS ADC your images of moon and planets as well as your observations near the horizon become significantly sharper and more detailed.

• Corrects the color shift (Dispersion) of our atmosphere - less color fringing, more sharpness and detail
• Convenient operation with eyepiece attached - simply rotate the lever and notice how the sharpness of your view or camera image improves.
• The principle behind the ADC is simple - two prisms are shifted relatively to each other and thereby compensate the color shift of the atmosphere (see image)
• A ring scale allows for reproducable adjustments
• Simple adaptation on the telescope side and eyepiece side via 1.25" receptacle and T2 thread
• Ultraslim design - the TS ADC can even be attached to binoviewers - height without T2 connection parts only 29 mm from T2 to T2
• Usable among others for observation and photography of planets, the moon or double stars
