humedad relativa

Día estraño con sensación térmica más alta que normal. Madrugadores cómo yo disfrutaremos de una humedad relativa de 100% a las 07:00 horas.

tulip equinox

With the equinox today at 16:21 CEST and 12 hours darkness to play with last night, what better time to enjoy the cooler nights than with a tulip. Humid with rocío but decided to persevere. With the sensor at its coolest since May, the patches in the background were less in evidence. Can't be bad.

surreal sadr

I wonder if Joseph Turner ever looked through a telescope? Turneresque clouds surrounding the star Sadr. The haze from the full moon may have added to it.

poor man's H-alpha

Quite pleased with this even if they do charge $20 to ship a $10 filter.

bucle del cisne

Had a go at loading b and r channels and deconvoluting them separately in StarTools. b 2.8, r 1.5 then combined them with g. Not bad.

a dark nebula

Just about to give up on this one. Here's what I posted to SGL
After many epic failures in capturing a dark nebula, this finally fell out. After colour balance, this must rank among the most difficult bits of processing. Or far more likely, me being thick. I found by accident; the second stretch (or in StarTools speak develop) seems critical. So instead of using the big autodev hammer for a second time, I developed a few % at a time. Still a way to go: I've now lost a lot of the cute little bright nebula and the stars have lost colour. No surprise that the rest of the colour balance is not good either. Anyway, at last I got a dark nebula. Any comments positive or otherwise most welcome.

velo este

Not quite Hubble, but at least the colours are realistic. Ooops, no. Can't say that. It suggests arrogance. €150 ex-demo telescopes with fingerprints on the lens indeed.
