This field flattener is designed to work with the Altair 115ED Triplet Wave Series Refractor with M63 2.5" CNC Focuser. It has an M48 rear thread adaptor for connecting your DSLR or CCD camera.
This reducer - flattener is designed to work with the Altair Astro Wave Series 115mm EDT-X FPL53 102mm F7 Super ED Triplet APO.
It consists of two components:
The flattener body containing the optics, with M92 male outer thread on the telescope side and M72 female inner thread on the camera side
An M72 to M48 adaptor-spacer with M72 male outer thread on the flattener side and M48 male outer thread on the camera side. The adaptor has a 21.62mm optical length, to give 55mm sensor to flange distance.
The Altair Astro 60mm finder also has many more features than your average finder scope:
This finder is right angled for more comfort, with a corrected field (i.e. not mirror-reversed like other finders), so objects actually match their orientation in your star chart.
The focuser can also be rotated 360° and locked in seconds (requiring some re-alignment afterwards). The 10mm larger objective and a little extra power compare to 8x50 finders, yet has almost the same size and weight.
The included quick-release finder base has 4x 4mm slotted holes in the base allowing you to fit it to most telescopes on the market. (The mini-dovetail wedge on the bracket will fit any GSO or Skywatcher telescope directly in fact but we suggest you use the included base if it fits the tube, because it has 2x clamping screws, for better alignment).
The CNC machined bracket is light yet rigid to keep alignment. Nylon tipped screws do not damage the durable high quality and moisture resistant powder coated aluminium tube.
All objective lenses are anti-reflection coated and the tube and dewshield are internally blackened to increase contrast. The included illuminator has a variable setting, which illuminates the cross hairs in the eyepiece. The included eyepiece has a dark field illuminated cross-hair, so you can easily see it glowing faintly against the background sky, an upgrade for standard finders with dark cross-hairs.
The high quality 1.25 FMC illuminated eyepiece has good eye relief for glasses-wearers, and a wide field of view. It has a side-port to screw in the included variable darkfield illuminated reticule, and the finder can be very easily focused, using the included helical focuser integrated with the prism diagonal.
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
