Astronomical targets

Defining interesting objects beyond our solar system

Astronomical targets
Now that I have a telescope, I need to find something to look at in the sky. Saturn and Jupiter were pretty easy to find since they are so bright. Nevertheless, the first photos taken look ugly. I compiled a list of potentially interreting targets. Let’s see, if I can find and recognize them. Some remarks to the following text All terrestrial position related times in here are given for Mainz, Germany (50°N/8°E) if not mentioned otherwise. [Read More]

Finding my way through all parameters

Which child, in some point of its life, did not want to take a closer look at the planets, stars, galaxies, … in the sky?! At least I did and finally, after taking some pictures of the full moon lately with a telephoto lens I remembered those wishes and bought myself a telescope. Nevertheless, I do not only want to look at the sky but also take beautiful photos, now. So I started my search for a beginner-telescope with the ability to attach my digital mirrorless camera (DSLM). Although a telescope is defined by its construction and two numbers and the two numbers of the eyepiece, it took a while to understand all the relevant parameters that could be calculated from those four numbers. So here I write about my way, how I found one.

My Panasonic/Lumix DMC-GX80 contains a build-in function “Post-Focus”, where the camera takes several pictures with varying focus (Example image). Lately I was a bit disappointed by the results and I looked up the internet for alternatives. On Focus Stacking Macro Photos by Pat David I found a pretty easy and description. You need your pictures with varying focus (here shown 3 out of 30 I took). Ideally take them with a tripod and remote control.
