Last week the weather was horrible all week long. Forecast looked consistenly cloudy. Then my wife suddenly mentioned she saw stars outside. What? WHAT? How could I miss this? I quickly pulled out all the equipment but it was already late and pretty cold so it was not a good start rushing outside like this.
I quickly set up the scope, found out that my wife threw out my bahtinov mask by accident, battery of dslr was half empty, and after shooting for first few minutes I realised my scope was way too warm and focus was chanigng continiously. On top of that, my esprit tends to have pinched optics when not at outdoor temperatures, so stars had weird shape.
Also, I did not have a good night of playing around with my settings and longer exposures, so since things started of bad anyway, I decided to play around. Temperature was 16F. I tried 10, 30 and 60s exposures on Orion, and decided I would look inside what worked. Pretty quickly lens was fogged up too.
As said, focus was shifting during my session, but in the end I decided to give my 25x30s on Orion a try in Siril. Focus got worse over the session, stars had weird shapes, but I think that my 12 minutes on Orion still give a pretty good result. Bortle 4. I personally like the trapezium part. Details are slightly visible, but in some way it looks burned out white, which is on purpose because I love how it can look like a bright exploding core. hdr versions sometimes seem too fake for me. of course purely personal and artistic approach, rather than correct aproach.
Just wanted to share the experience, and I hope I have the opportunity to give Orion 2+ hours one of the next weeks. Can't wait to see those dust lanes and brighten up some parts with lower noise, and hopefully have decent colors too.
dslr is charged, bahtinov mask ordered, and excitement is loaded
ps; 12min only gave slight blue/red color but it didn't look satisfactionary so B/W instead. it just looks better.
