Thank you! Yeah the 12mm is very forgiving in long exposures and winds shaking the tripod, though you can see both trailing and wind shake in the stars if you zoom all the way in.

I'll try tracking it with the 12mm at some point, it should allow for over 2min individual exposures without trailing!

Thank you so much! I could see lots of details with my eyes, it's a properly dark spot there! You can't see any of the colors, but you see the shapes in the nebulosity pretty clearly.

Bonus single shot of my tent under a tree

 

There's about 30 x 22 sec lights for the sky, pasted over a 2,5 min single shot of the foreground.

Shot with a stock Sony a6000 and a Samyang 12mm f2.0, untracked, under Bortle 3 skies.

Stacking was done in Siril and the rest in Photoshop.

Feedback appreciated!

True AI will have huge energy requirements. Maybe it'll work with humans to find a solution to that problem. I'm sure it'll work out just fine, until Keanu Reeves shows up and starts showing off his kung fu skills

Normally the trapezoid shape can be corrected, but on the really cheap models I wouldn't count on it working that well.

You could also look at your local second hand markets for a better quality one at a reasonable price, but make sure to check if replacement lamps are available and if they're easy to replace on the particular model.

Get a projector with at least 1080p actual output resolution.

Most entry level ones have terrible lenses which means you'll need to experiment a bit with how high you'll mount them cause they need to be dead on to display properly, otherwise half the screen will be blurry. I highly recommend a cheap aluminum camera tripod with a center collumn for height adjustment.

For screen I bought a white roller blind for like 8 bucks from a home supplies store and mounted it by passing a string through the tube and tying the ends to whatever worked best. In terms of picture quality it's exactly the same, but if you can afford an actual projection screen and haul it around then do that.

For sound I would recommend a battery powered Bluetooth speaker because they're cheap and easy to carry, but you may experience a slight sound delay which can be solved with a 3.5mm aux cable in the aux port.

My final suggestion is to get a used Nintendo Wii with sports and a couple of controllers, endless fun for the right crowd.

Its most important part is to make Microsoft money.

Read the article here and see if you can spot when games became a side quest and making money became the main one.

If they launch a submarine lime people are gonna park them on land. Even if you clean em all out of the rivers they'll be back in there in no time at all

Imagine being in a 40 million dollar fighter jet, looking down with your augmented reality visor, seeing a bunch of tents with children around them and going "yup... That one tent right there looks like Hamas to me!"

It can most definitely be denied. It can't be avoided or fixed, but it can be denied

Trifid and Lagoon (lemmy.world)
submitted 2 weeks ago* (last edited 2 weeks ago) by Zer0_F0x@lemmy.world to c/astrophotography@lemmy.world
 

My first attempt at the Trifid and Lagoon nebulae!

A few minutes worth of 30sec exposures, 10 darks (had to leave in a hurry) and 20 flats/bias.

Edit: Shot with a 500mm f6.3 camera lens and a stock Sony A6000 on a Star Adventurer.

Edited with Siril, then Starnet++, then Photoshop and some minor adjustments in Lightroom.

Feedback appreciated!

 

My first time trying to shoot the Horse Head nebula! I have a stock Sony a6000, which cuts out most of the hydrogen red signal, but thankfully enough got through to at least make this a solid attempt.

The data is about 45 minutes worth of 30 second exposures out of my Sony and a Ttartisan 500mm f6.3 lens, on a star tracker.

Due to the very limited total integration time and the stock camera I had to stretch pretty far while fending off artifacts here and there.

Overall I'll take it, will revisit in the future.

Feedback appreciated!

 

My 5th time trying to image a seemingly easy target with something being off... This time I must have nudged the lens out of focus slightly and there was some dew forming on the lens that I hadn't noticed. This hobby sure has a steep learning curve!

Still, decided to not throw away the whole attempt and did a quick processing. It's about 45 minutes worth of 30 sec exposures at 500mm f6.3.

Feedback appreciated!

 

63 x30 sec tracked, 10 of each calibration frames. Stock Sony A6000, ISO 1600. 500mm f8 ish with a ttartisan lens.

Feedback appreciated!

 

73x30 sec of the Orion nebula, with a stock Sony a6000 and a ttartisan 500mm f6.3 on a StarAdventurer.

Lens was wide open, which introduced lots of aberrations on the brightest stars. Will try stopping down next time. Also, focus wasn't perfect and I had some dew issues.

No calibration frames, either, I was just testing the lens for the first time.

Stacked in Siril, stretched in photoshop, final touches in Lightroom.
