ARISS SSTV Expedition 64 MAI 75

On January 28 & 29 the International Space Station (ISS) was transmitting 12 images as part of Expedition 64 MAI 75 Jan28&29, 2021.

I used webSDR from Nurnberg (Germany) to connect with ISS via 145800Hz. Pictures were decoded with MMSSTV. In total I followed 5 ISS flights resulting in 6 images : 2 good ones, 2 moderate and 2 bad ones. 

Guiding : Preparation

I'm starting a new chapter in astrophotography : guiding. The intention is making sharper pictures and pictures with longer exposures.

As a first step I will be experimenting with my TLAPO 80/480 f/6 and I will use my ZWO ASI 224MC as guiding camera.  

My preparation in a nutshel :

    Hardware : 

                - an USB-hub 3.0 with 4 ports to connect both cameras and mount

                - mini(guiding) scope ZWO 30f/4

    Software:

Some interesting information I used to start :

- Setting up a Skywatcher mount with ASCOM platform and EQMOD

- Beginners guide to setting up and using ASCOM to control your astrophotography gear - Part 1&2

A whole day Halos

High clouds and ice chrystals are responsable for halos around the Sun. Yesterday halos could be observed the entire day.

Rare Ice Spike or staligmite of ice

For the second time (first time February 19, 2013) I was able to spot the rare Ice Spike and this in my own garden. Temperatures dropped below freezing point (-2.5°C) and this created a Ice Spike. 

Ice Spikes can only formed when all circumstances are perfect. Circumstances are influenced by the purity of the water, amount of water, shape of the "container", surrounding temperature, temperature gradient and probably the air circulation and humitidy of the surrounding area.

Jupiter-Saturn Close Approach December 2020

I'm looking back at the close approach of Jupiter with Saturn. The closest approach or conjuntion took place at december 21st 2020, but due to bad weather nothing could be seen. However the days before and the days after I was able to make some pictures. An overview is presented.
