Product information

A 2" Filter Holder with Male T2 thread on the rear, enabling direct connection to Altair Hypercam.

Includes one 2" Filter Slider.

Note: Order extra version 2 sliders to fit Version 2 Magnetic holders because they have the correct polarity.

  • T2 female thread on the front enables connection to various T2 flatteners and reducers such as Lightwave Reducer/Flatteners.
  • Optical path length is 17mm, therefore you need to incorporate this amount in your spacing calculations.
  • The maximum height the filter can protrude from the surface of the slider is 6.85mm. The threads of the filter are buried, therefore this measurement does not include the threads of the filter. There is allowance for maximum filter thread depth of 3.6mm.
  • Includes a 2" filter holder/slider.
  • Additional 2" and 1.25" Filter Sliders are available separately with product codes CASS-125 & CASS-2.

Compatible with Altair TriBand, QuadBand, and 2" filters, Altair 2" Narrow-band filters and most other brands using an M48x0.75mm filter thread.
Rear male T2 thread fits directly into the Hypercam front-end.
Front female T2 thread fits directly to the Lightwave 0.6x 0.8x reducers and 1.0x flatteners.
Starwave T2 Spacers and Extensions are also compatible allowing you to make up the correct spacing between camera sensor and optics.

General usage and safety advice: Do not use for solar imaging to hold an ERF (Energy Rejection) filter or any other filter in front of Hershel Wedges. Filters are orientated correctly as shown in the product images, turning the filter slider around will impair the performance of your filter. When taking flat-frames before or after imaging, it's advisable not to remove the filter holder or replace it, because this could cause changes in the position of dust particles which makes them difficult to cancel out. When taking darkframes in brightly-lit situations, it's advisable to cover the filter holder and telescope focuser, or entire telescope with a dark cloth.
