With the first light planned for the end of the decade, the ELT and its groundbreaking 39-metre main mirror will take on some of the biggest challenges in and, ultimately, help us understand our place in the .

Stacking software and affordable sensor technology brought citizen science to another level as well.
I recall sweating blood when developing 30min long exposures in Ilford Tecnical Pan F, not to fuck up development. Usually it was fucked up nevertheless on tracking issues...

For planetary, registax. But I have the hobby on hold… haven’t had a good session in the last 2 years. I’m getting lazy and I’ll probably get a robo-scope -vaonis or seestar- to do the work for me.

I try to collect as much FOSS available somewhere as possible during the monthly refresh cycle, it would be great to attract more astro enthusiasts to topic 🙂

What is really mind blowing is the image processing technology allows me to capture images close to those from Palomar with a 6 inch SCT paired with a photographic sensor plus some neat processing tricks.

Palomar has been the pinnacle of optical instruments.

How far has science got from there. I still can't believe it. JWST. Rubin Observatory. This will get ready in my lifetime. I am so curious.
