Zum Unterschied CMOS- / CCD-Filter
Die völlig neu konstruierten, CMOS-optimierten Filter arbeiten hervorragend mit allen bestehenden Kameratechnologien, seien es CMOS- oder CCD-Chips.. Allerdings – wer CCD-Kameratechnik besitzt, wird mit unseren bisherigen, extrem preisgünstigen, CCD-Schmalbandfiltern weiterhin hervorragend arbeiten können. Aber "Das Bessere ist des Guten Feind".

Baader Ultra Narrowband filter unter the sky
My general opinion on performance, supported by the tests carried out and my experience with other high-end products, is fully positive. I believe that they can be equated with the most famous brands, with the advantage of a cheaper price.
Of course, as soon as I need them, I will seriously consider using these filters for my setup.
Attached the final result of my tests.
Mr. Fransceco di Biase had the opportunity to test the new Baader Ultra Narrowband Filters 36mm in unmounted version in his small observatory with a sliding roof under a suburban sky (19.40 SQM) and he sent us a detailed field report. We are very pleased about the positive feedback on the new CMOS-optimized Baader 3.5 / 4nm Ultra-Narrowband Filter.

3.5nm Ha Ultra Narrowband CMOS Optimized
I have only got to image with the Ha filter to any extent. I am using a ZWO ASI 294MM P. It is set up in a dual rig with the exact OTA and imaging train. I have the new CMOS filters in one wheel and the older version of the Ultra Narrowband in the other. The contrast was noticeably improved with the CMOS filter. I just got to start using the SII and as quick comparison, I had almost no data present on a 900 sec image of the Heart Nebula. On the other hand, with the new CMOS SII I had lots of data with the same exposure time. I sold!!! So much I just received my second set today for the other filter wheel. By the way this was imaged under a 98% Full Moon. Almost directly in my targets line of sight. 44x900s for 11 hours!
Thanks for your review! Regarding the indicator for 1.25" filters:
Traditionally 1.25" filter cells were meant to thread onto an eyepiece. For this reason it is almost regarded common knowledge which side of the filter needs to point towards the telescope.
It is quite rare that there is a provision at all to thread a filter in reverse order. For this reason we are glad to take this opportunity to point out, that its always best to mount a filter cell in the way, which is commonly acknowledged.
For manufacturers of accessories that allow the customer to mount the filter cell in reverse direction, it might be in order to also remind them to inform their customers, that this way of mounting a filter may result in the filter being installed in reverse.
For skilled users certainly it would be possible to flip the filter in the cell if needed (by removing the retainer ring that holds the filter in its cell – as we deliberately do not tighten these retainer rings with force). More information why our filters may "clatter" also here: www.baader-planetarium.com/en/blog/information-about-baader-filters-and-filtercells
High Contrast!
Should be an indicator for the direction to install with the 1.25" Cell
Baader 3.5 / 4nm Ultra-Narrowband Filter-Set
Excellent details showing. Crisp nebulosity, no bloated stars. Truly impressed. My 31 mm unmounted filters did'n show any edge shadowing on ASI 1600 MM. Over all highly recommended.
Thanks for your review. With the old filters, the direction in which the filter should point to the telescope / sky was indicated by a small arrow on the side. With the new CMOS-optimized filters, the black edge itself, which only extends about 1mm into the front of the filter on one side, serves as a marker to indicate that this side should show towards the telescope. We call this the "filter front side indicator".
Perfomance
Could have telescope side indication marked on side unmounted filters (31 mm).
Amazing contrast and tight stars!
I just installed a set of Baader Ultra Narrowband filters on my C11 Edge. The results have been outstanding!
Cost, lack of halos, improved contrast
Nothing!
