Re: Milky Way
The bit i'm not entirely sure on is knowing where to point the camera! Generically south, but is it obvious to the naked eye in a dark enough area? I have downloaded a night sky app to my phone to help!

Re: Milky Way
Nobody has mentioned the 500 rule. This calculates the maximum exposure time before the Earth's motion starts to turn the star points into little trails. For a 17mm lens you need to double to make 34 (full frame mm equivalent) and then divide 500 by it. Rounding up, that's a maximum of 15 seconds.
Actually, for Micro Four Thirds you can make it the 250 rule and there is no need to compensate for the crop factor, just divide the focal length (17) into 250. For a 9mm super wide you can expose (250 divided by 9) for 28 seconds. The longer the exposure the better of course and this is one reason why a moderate wide angle like a 17 isn't ideal for milky way shots, apart from the fact that it doesn't cover enough of the sky.

Re: Milky Way
The 500 rule is a good guide elongated stars are not pretty.
BUT if you set your ISO high enough then you will be amazed at what you camera can capture in under 20 secs. Certainly more than the naked eye. If you look the at link in my post #2 it shows you whats possible. Not sure what phone you have but Celestron do some free software called Sky Portal which is very good. Highly recommended. It works on Android phones, apple phones and iPads. It certainly will help you in deciding where to point. https://www.celestron.com/pages/sky-portal-mobile-app |

Re: Milky Way
I've spent quite a bit of time trying to get good Milky Way photos with EM1.2 and never really been very satisfied, and I'm lucky enough to live somewhere with very low light pollution.This is fairly typical of what I've managed to get in a single exposure (this was taken in December - it never gets dark enough at this time of year for us to see the Milky Way. The wrinkly appearance of the sky is due to the phenomenon of air glow - it's relatively uncommon to see it as clear as this) )
EM1.2, 7-14mm Oly at 7mm, 30s f2.8 ISO 6400: ![]() ![]() I think you do need a bigger sensor to really get the detail, or possibly I'll need to have a good look at image stacking, which I've not yet tried.

I assume the airglow is constantly changing so stacking a few shots taken at say 5 minute intervals may help as long as you align them first. Many photo applications can do this for you. |

Re: Milky Way
Whatched a tutorial on a free Milky Way stacking program called Sequator, looks user friendly with good results.

Re: Milky Way
Can I presume that David's shots (which I would have been quite pleased with
![]() I can see some star elongation and I actually wonder if the focus is very slightly out? Ian

Re: Milky Way
Focus could well be slightly off - it's always a problem at night. I usually manually focus to the infinity sign on the focus ring and hope that with the wide angle lens there's enough dof to give me some leeway. Star elongation due to exposure length is usually more noticeable at the corners.
