It's a miracle that in October they gave us sky and a real one - not like usual with little clouds, but as it should be.

This is the first light of an IR filter from Aliexpress: it screws onto the front of the lens, diameter 77mm. It passes something broad (20-30 nm?), not like astro filters at 3-7 nm.

The camera is astromodded. On a tracker without guiding, computers, and the like.

Next time I'll try to make the stars whiter and not squash them through bxt (right now they're brown because it was shot through a red filter and it's surprising that anything is visible at all)
