Description

This is my first try with the Optolong CLS clip-filter for Nikon. My Nikon D7100 is not modified for astro-photography. I can crank up the exposure time and ISO without getting a too bright image. Without the CLS filter I usually have a almost daylight-bright image after 2.5 minutes at ISO 800. Here I shot for 2.5 Minutes with ISO 1600 and the image is still quite dark. Although it has a strong blue tint which I have to process. I did not hit the focus 100% so the stars hat a slight reddish coma. Nevertheless, it looks like it can improve the imaging in my backyard (Bortle 5) quite a lot.

Best,

Jan
