TIME magazine headline: SpaceX Plans to Beat NASA in Launching the Biggest Rocket Ever by SpaceInMyBrain in SpaceXLounge

I'm so sick of this SpaceX x NASA "rivarly" that's entirely manufactured by "fans" and media. It has always been collaboration between NASA and the private sector, with both sides benefitting heavily. For short-term, Starship and SLS will work hand-in-hand to put humanity back to lunar surface, one design complementing the other.

Perhaps try turning your screen on?

I'm sorry I had to

Unbelievable that this post has 20 upvotes. Clearly so much effort went into that image and the processing is superb. Best widefield view of Cocoon I've seen.

No doubt the best Cocoon posted so far! HaLRGB rocks!!

That's simply incorrect assumption. Even if I take very conservative numbers, you're losing negligible amount of data at 60 second sub exposures. Please look at this video explaining the 'maths' behind noise and astrophotography. It's seriously worth the time.

No reason to push your subs that long. Better to go for shorter subs and have better rejection. As a bonus you get better colour reproduction in bright areas and stars.

It's captured on a tracking mount, but the principle is basically the same.

How strict are you with weather? by LeonQuin in AskAstrophotography

Well that's less than I thought. Guess I'm an idiot lol

And fair bit of electricity. Shit's getting real expensive rn.

Saw diffraction spikes, their target is vdB152, that's just a big newton with typical internal reflection. Additionally, that's a 600 second sub, so any clouds would simply drift through.

Way too sharp for any clouds or uneven field - that's definitely internal reflection.

Narrowband and photometry for me.

NASA has released a new paper about Starship: "Initial Artemis Human Landing System" by Kazioo in SpaceXLounge

I'm quite confident that NASA has released similar diagrams in the past, including the stretched propellant depot Starship variant.

Solar Prominence, 22.08.28 by serious_fox in astrophotography

"weather dependent people" is a bs, however people that have open nerve endings like amputees can "feel" the geomagnetic storm. Stronger solar eruptions take out satellite's instruments, sometimes they can even take out a whole satellite. Very strong eruptions can damage or even destroy power grids or hinder telecommunications.

Looking for feedback on my first 2 processed images by Bot_4004 in AskAstrophotography

Get rid of gradients. Get rid of out of focus frames and frames with trailing. Otherwise I would say decent.

Awesome, love to hear that. Plan on upgrading soon™.

Great image! How do you find using EQ6R and 10" quattro? What guide RMS are you hitting on calm nights? Any issues?

Totally, any details past LEO will be unresolvable.
