These filters are positioned within a thin metal ring with a full 26mm clear aperture that threads into the barrel of any standard 1.25" eyepiece or filter wheel that can accept 1.25" filters. They help to increase contrast and reduce glare and light scattering. Each filter is threaded at both ends to accept another filter if required. Filters come inside individual plastic cases with a transparent window.

This Opticstar 1.25" eyepiece is suitable for both visual observation and imaging these are all-in-one high-transmission deep sky filters.

1.25" Moon Filter with 13% light transmission from Opticstar.

1.25" Moon Filter with 25% light transmission from Opticstar.

This high quality 9mm Plossl Illuminated Reticule Eyepiece is ideal for use for guiding and aligning the telescope mount via the ‘drifting’ method that ensures accurate alignment. The Plossl eyepiece includes a 4-element, multi-coated optical system, dioptre adjustment, and double cross-line/bull’s-eye type reticule.

These high transparency filters from Opticstar are placed within a thin metal ring with a full 26mm clear aperture that threads into the barrel of any standard 1.25" eyepiece or filter wheel that can accept 1.25" filters.

For the use in CCD imaging this high-transmission filter will exclude any IR wavelengths beyond H-alpha showing a very steep desirable curve.

This Opticstar Light Pollution Filter improve contrast for all types of telescopes; especially effective on the Moon and planets where they will show additional detail. It will also darken the sky background to enhance many deep sky objects like galaxies and nebulae against a darker sky background.

The Opticstar Light Splitter prism diagonal can be used to track or auto-guide and image at the same time. It greatly helps to centre and focus objects to be imaged with a CCD imager or film camera.

This 1x C/CS to 23mm microscope adapter, enables any C-mount camera to be attached to any microscope that accepts standard 23mm occulars. It includes a locking mechanism to secure the camera to the microscope.

This Opticstar Light Pollution Filter improve contrast for all types of telescopes; especially effective on the Moon and planets where they will show additional detail. It will also darken the sky background to enhance many deep sky objects like galaxies and nebulae against a darker sky background.

This Opticstar 2" eyepiece is suitable for both visual observation and imaging these are all-in-one high-transmission deep sky filters.

Advanced illuminated reticule eyepiece, both Plossl 6mm and 12mm models include micrometric x-y positioning controls that greatly facilitate locking onto the guide star by turning the threaded controls and placing the reticule's cross-line pattern precisely at the desired point in the field of view.

A premium quality adjustable three-part T/1.25" camera adaptor used for prime-focus and eyepiece-projection astrophotography with SCTs and refractors. It can also be used with Newtonians that have the necessary focus travel (otherwise a barlow lens is required).

OpticStar PL-131C CoolAir Autoguider includes 1.3 MP Color CMOS. It was designed for mounts with ST4. The package includes 1.3mp Color video camera, computer-to-mount interface box and all cables.The PL131C CoolAir is a USB 2

The AG-131M CoolAir is a USB2.0 fan-cooled camera that offers exceptional performance and versatility easily outperforming cameras costing considerably more. The camera excels as a planetary (Solar and Lunar) camera with frame rates of up to 220fps

Astroart 5.0 is a complete software package for image processing, photometry, astrometry, CCD control and image stacking for CCD and film images. All major CCD cameras, webcams and DSLRs are supported by AstroArt. Focusing, autoguiding, imaging and scripting become easy and quick. AstroArt is also an open system with plug-in support. All programmers of C/C++, Visual Basic, Delphi can create new filters using the free development kit.
