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)
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...

Is there any instructional videos on how to install these filters into a camera?
Question by: Anthony on Aug 29, 2018 9:02:00 AM | 1 Answer(s)
Unfortunately, we do not have instruction videos and can't provide instructions for replacing the filters - they are for those who either know what they are doing or are trying to use a manual from the web on their own risk.
But we also offer a service to replace the filter, unfortunately we can only do this for customers in the EU: https://www.baader-planetarium.com/en/services/canon-camera-astro-upgrade.html

If I modify my dslr with a baader bcf filter inside the sensor, the photos after modification will be only red without any blue or green?Or just more red plus blue and green as before?
Question by: George Ntekas on Nov 17, 2019 8:53:00 PM | 1 Answer(s)
The Baader BCF is more open in the red part of the spectrum, means all other colours pass the filter plus some more red. This gives "normal" (daylight) photos a pink touch that you can correct in image processing

Will the BCF 2 Astro Conversion Filter fit the original Canon 5D (classic) model? I ask because it appears the ACF-3 conversion filter is no longer available.
Question by: David Wing on Mar 10, 2017 10:32:00 PM | 2 Answer(s)
Unfortunately the former ACF-3 Filter is indeed not available anymore. The BCF-2 (nor any other Astro-Conversion filter we currently sell) will definitely not fit the old 5D model. Sorry that we cant be of service.
Answer by: Baader Web Team (Admin) on Mar 13, 2017 2:42:00 PM
I read that the filter is not compatible with the old 5d; Is the problem in thickness or size?
Can not any filter be able to adapt it?
thank you so much
