Astrophotography – Some objects for beginners

Beginning with astrophotography can be a bit frustrating. You bought all the equipment and now you want to see some results. Now you are out there in the field. It is already getting dark and cold and you still have to get all the cables right… You still have to do the mount alignment and then you face some IT problems… When you fixed all that and you focused the camera, it is probably already dark and it is time to move the telescope to the object of desire.

You catch the first frame and… nothing but a couple of dots. You increase the exposure time but all you get are a few more and brighter dots. Your fingers are getting already stiff and you begin to ask yourself what you are actually doing out here. Your wife is at home on the warm and cosy sofa drinking a delicious cup of tea…. welcome to the world of astrophotography!

An article from lost-infinity.com in the “Dark Sky Travels Magazine”!

Recently Dark Sky Travels Magazine contacted me and asked if they could publish one of my blog articles in their magazine. The article describes how one can use DeepSkyStacker to stack conventional DSLR camera RGB frames. Of course I didn’t say no and in the end it just happened and I saw my article on page 42/43 in Issue 4 of the DarkSkyTravels magazine!

I am very happy about that opportunity and the chance to share my experience this way.

Thanks and clear skies!
