Which side should face the telescope?
  • Baader CMOS LRGB Bandpass Filter Set, suitable from f/15 to f/1.8
  • Anti-reflection RGB filter (red/green/blue) with extremely high transmission of the respective color channel, thus simultaneously reducing stray light and reflections to an unprecedented level
  • Including UV/IR cut (L-filter) with 98% transmission over the entire visible spectrum from 420 - 685
  • Balanced RGB design allows subframes to be taken with the same exposure time – extremely important for automated imaging tasks
  • Reflex-Blocker™ hard coated and planeoptically polished – with sealed coating edges (Life-Coat™)
  • Blackened edges all around, with filter-lead-side-indicator in the form of a telescope-sided black outer rim
  • Optimized for modern CMOS cameras, but likewise excellent for CCD camera technologies

I am about to purchase a mounted 1.25 LRGB filter set for a QHY CFW3. (i had the unmounted ones already) Is there any problem with the thread of the 1.25 mount to the filter wheel slot? I've read in some forums that the thread is not exactly the same.

This new generation of Baader CMOS-filters features:

CMOS-optimized Baader Filters
  • Increased contrast, matched for typical CMOS quantum efficiency and s/n ratio
  • Reflex-Blocker coatings, for largest ever freedom from halos, even under most adverse conditions concerning aux-optics
  • Identical filter thickness to existing standards, with utmost care for parfocality
  • Blackened edges all around, with filter-lead-side-indicator in the form of a telescope-sided black outer rim, to additionally eliminate any reflection due to light falling onto the edge of a filter
  • Each filter coated individually, with sealed coating edge (NOT cut out of a larger plate with coatings left exposed, read more)
  • Life-Coat™: evermore hard coatings to enable a non-aging coating for life – even in a most adverse environment

Don´t be misled.

These all new CMOS-optimized filters work magnificently with all existing digital camera technologies, be it CMOS or CCD. However – an owner of CCD-camera-technology will still find our previous, extremely affordable, narrowband filter technology to be fully apt for excellent imaging. But: "the Better always is enemy to the Good".

Ausgezeichnetes Filterset für Mond und Planeten
Für die Mond- und Planetenfotografie kommt sowohl eine Farb- als auch eine Monokamera zum Einsatz. Die Monochrome Kamera nutze ich für das Lucky Imaging von Mond und Planeten, insbesondere um eine möglichst hohe Auflösung zu erreichen.

Bei der Auswahl der Filter waren für mich die Qualität und die die Transmissionskurve entscheidend. Der Filtersatz konnte mich im Vergleich zu den Konkurrenzprodukten überzeugen.
Die Transmissionen der einzelnen Filter sind gut aufeinander abgestimmt. Wie dem Diagramm zu entnehmen ist, sind die Kanten den Baader-Filtern viel steiler und decken somit das Spektrum augenscheinlich gut ab. Auch die Oberflächengüte scheint ausgezeichnet zu sein.

Das Filterset kann ich uneingeschränkt empfehlen.
