First stacked astrofoto

Orion belt and nebula

First stacked astrofoto
On saturday morning I woke up pretty early and when boiling water for tea, I saw quite a lot of stars from our south facing kitchen window. I took the chance to take some pictures of Orion, which was still high enough. At that morning I was not able to take too many picture, there was a plane crossing on two images and then clouds came up, that’s why I have more darks than lights. [Read More]

DIY Focus mask

Spending 20€ versus self-made

DIY Focus mask
Getting the stars in focus is not that easy. Sometime you find the statement “turn the focus to infinity”. However, at least for my telescope and my camera lenses “infinity” is even behind the focus. For that, there exist so called focus masks with the Bahtinov mask being the number one found in the internet. However, instead of buying one, it is pretty easy to make a simpler focus mask on your own. [Read More]

Sky Map

Polar plot of some constellations, galaxies, star cluster, nebulas

Sky Map
The last days were mainly cloudy and/or foggy. So there was no chance to look at the stars in the sky. Nevertheless, there was a bit of time to look up more interesting objects and since I once was a geographer, I like maps and I started inpired by the simple star wheel I have, to create my own map. So I started to code it up in python and store it on Gitlab. [Read More]

Astronomical targets

When to look at which interesting deep sky objects

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 interesting 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]

Telescope

Finding my way through all parameters

Telescope

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 mirror less 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.
