Hi! The greenish top image is looking as if it should look like. The polar light was probably not too strong as I could not see very bright green patches in your image. There is very little light ...

Hi! Can we get some examples to look for the problem, even if you are not happy with the results? Lack of color for the eye but color on the camera display is normal for weak to moderate polar ...

Ups, clicking on your link I get the comment that the video was removed by the user!? Is that my firewall or is there another issue?

Hi! No, there was nothing. Kp=3 max in the past 24 hrs. Solar wind density is recently picking up, but as I want to shoot the milky-way tonight I would see polar light rather as light pollution.

Hi! Yipp, that’s also my solution. I’m using 12V rechargeables batteries (USB has 5V) from Ebay, with dew-heaters. You can also adjust the temperature of the dew-heater and the ‘DSLR-buddy’ allows ...

Hi! As I was asking for a recommended startrail book/web page in one of my previous replies. I found this tutorial for startrails in the internet and - based on a short test - it's looking ...

Hi! Here is a test of three 14mm lenses: Two from Samyang/Rokinon and the Sigma A 14/1.8. My copy of the Sigma has a comparable amout of coma. https://amazingsky.net/2017/09/22/the-fast-14s-face-off/ ...

Hi! I'm shooting polar light (pl) from 60 N, so I'm close to but not under the pl oval. 24mm on FF is OK for single-row panoramas (recommended), but f/2.8 is a little bit slow. I'm often using ...
