Antlia Highspeed Narrowband Filter with 3 nm Bandwidth

Nebula filters from Antlia offer extreme contrast. This allows the astrophotographer to achieve a very good result even with considerable stray light from cities or from the moon.

The quality features of Antlia narrow band filters at a glance:

High light transmission and smallest bandwidth to maximize contrast.

Steep spectral profile minimizes halos around bright stars

Single substrate to eliminate internal reflections

Use in light-polluted areas and dark locations

Extends imaging time in moonlight conditions

Antlia Highspeed filters are optimized for systems with f/2.6 to f/3.6 focal ratio

Transmission is at least 90%

All Antlia narrowband filters are blackened at the edges to avoid internal reflections of stray light

Superior optical reliability reduces the time and effort required for post-processing of images

Substrate:	Optical substrate from Schott
Filter thickness:	2 mm
Cell:	metall cell with M48x0,75 filterthread
Peak transmission:	min. 90%
Surface quality:	S/D (scratch/dig)= 60/40 (Refer to MIL-O-13830)
Surface accuracy:	Lambda/4 or better

Question:
Do I have to pay attention to the orientation of the filter when installing it??

Answer from Teleskop-Service:
The installation direction of the filter does not affect the imaging result of deep sky photography. This is because both sides are coated to improve transmission rate and cut-off data, and it is no longer necessary to determine which side faces the cameras for optimal performance.
