Altair 2" Filter Holder with female M48 thread on the front (telescope side) and M54 male thread on the camera side. This fits the Hypercam full frame cameras such as 24CX, 61MFX and 61CFX.
Includes one 2" Magnetic Filter Slider.
Additional sliders are available separately in 2" and 1.25" sizes. See Product code: MAGF2-SLIDER
A special stackable magnetic storage case is available to protect your sliders with filters installed. This allows for quick convenient filter changes. See Product code: MAGF2-SLIDER-HOLDER-GREY.
Note: Order extra version 2 sliders to fit Version 2 Magnetic holders because they have the correct polarity.
- Enables connection to flatteners and reduers with M48x0.75mm male thread, such as Altair PlanoStar or Starwave, and Altair or other cameras with M54x0.75mm female thread.
- 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.
Compatibility:
- Compatible with Altair TriBand, QuadBand, and 2" filters, Altair 2" Narrow-band filters and most other brands using an M48x0.75mm standard 2" astronomy filter thread.
- Scope side female M48 thread fits Altair Quad APO Astrographs.
- Rear camera-side M54 thread is compatible with full frame Altair Hypercam 24CFX and 61MFX / 61 CFX cameras.
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 dark-frames in brightly-lit situations, it's advisable to cover the filter holder and telescope focuser, or entire telescope with a dark cloth.
