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

What are the threads and pitch of your 1.25" and 2" filters?

Question by: Anders G. on Sep 20, 2017 12:55:00 PM | 1 Answer(s)

Rating of Question

Our 1.25" filters have a M28.5 male (and M28.5 front female) thread / our 2" filters have a M48 male (and M48 front female) thread

Both thread sizes come with our proprietary pitch - which is not the same for the female and male threads.
This is our own proprietary "emergency solution" for uniting a world were manufacturers all over the world copy from each other - to the point that there are almost a dozen different pitches in use for male and female threads. Traditionally US-companies used to do a UNF-based pitch and the rest of the world went for metric threads - but these do vary from 0.5 to 0.75.

For this reason it does not make sense to publish our non standard pitch because our pitch is made to cope with all existing metric and US-pitch standards - and as said - our solution has evolved from sheer necessity. It is a mixture of a queer pitch and under-/over-dimensioning . We will not want to declare this as a standard and get bashed up for it. It works for us and is a result of 20 years adaptation to fit our filters onto all crazy threads we have seen. And inspite of this - every now and then there comes another "dragonboat-eyepiece" were even our filters may not fit...

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.

Description

Details

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".
