A quick shot of a Comet P41/Tutttle-Giacobini that was passing through the constellation of Ursa Major in March 2017.

Image taken on 25th of March 2017 with my Nikon D500 at ISO 5000 and exposures of 40 seconds using SkyWatcher 250/1200 instead of some camera lens.

Warmer coat for Larping

Here is a quick tutorial on how to create a warmer coat that can be used for the purpose of the fantasy an medieval LARP events. My plan was to create a warmer and water resistant (not water proof) that can be used for different events or characters. Its design is based on a piece of clothing named gambeson. Historically it was used a stand-alone protective layer or worn under metallic armor.

Fabric used for the creation of this piece:

  • Wool fabric
  • Old bedding fabric used as a filler material
  • Another layer of fabric for lining
  • Assorted sewing materials
  • Buttons

Fabrication process:
1. Cut out all need layers of fabric. In my case I used 4 layers of filling, upper woolen layer and cotton layer as lining. All six layers together form a sturdy and warm clothing.

2. Using parallel seams I quilted all the layers together. This prevents them to move independently. Quilting patter can wary, depending on your preferences.

2a. Optional: Stuff additional fabric between the quilting seams for even more warmer clothing with additional protection.

3. Sew all pieces of the clothing together. Length of the sleeves can wary depending on your preferences. I created shorter sleeves so the piece could also be used in the warmer months. Shorter sleeves also allow for greater flexibility of arms.

4. All outer visible parts of the clothing should have hemmed edges.

5. Add buttons. For this purpose I used 6 metallic buttons with slightly unusual look.

6. Have fun wearing it. Mine was already tested in few events.

Gaia Sky


A nice program for the visualization of the data gathered by the latest astrometric satellite Gaia that was launched by Esa.

I have contributed to the open source program by translating it into Slovenian language, therefore allowing more people to use this program even if they do not understand the English language.
