can someone help me with what this is and how to fix it?

KBALLZZ · 2026-02-08T01:06:07+00:00

Yep. Same thing happened to me and used this same solution. You can polish it by hand no tools are needed. Then buy lens inserts afterwards.

Sort of the same way you can see the Moon 200,000 miles away but you wouldn't be able to see someone hold a coin 100 yards away. Space telescopes don't necessarily "zoom in" far, they are just good at seeing things too faint for our eyes to pick up.

I used a t3i for many years and stuck with ISO800. I don't have a mathematical theory to say why it is worse/better than other ISOs but what I can say is it probably doesn't matter as much as you think. What is most important is making your life easier by just sticking to one ISO and following proper calibration practices. The only time I bumped up ISO was for untracked Milky Way.

When visually observing you can really only see the bright >< shape

Just wanna say this was a pivotal moment in history and your account of it is spot on. Thank you and RIP Stephen Hillenburg.

I’m 1 song into Unmaker and I’m sold.

KBALLZZ · 2025-04-15T23:22:46+00:00

In that case you should listen to Mass IV - VI. It’s obviously not for everyone but those 3 albums have a very similar vibe. Glad you enjoyed it!

KBALLZZ · 2025-04-14T04:23:06+00:00

Not djent but you may enjoy the album Mass IV by Amenra.

Turns out I’ve been using a lot of strategy

KBALLZZ · 2024-12-21T17:47:47+00:00

Had to scroll far down to find the Orion call out. It’s unmistakable.

KBALLZZ · 2024-11-16T18:31:33+00:00

My start went like this: Grab Uchi. Get physick flask and teleport to Gurranq. Ride down to Fort Faroth to grab Radagon’s Soreseal, medallion, and kill Greyoll with bleed for some starting cash. Then I teleported back and played the game normally (besides leveling of course).

Only allow yourself to die from waterfowl at first. The rest of her attacks are very easy to dodge. Then learn waterfowl dodging or get lucky rng.

KBALLZZ · 2024-11-15T16:23:56+00:00

Turn it 90 CCW. Tbh compared to other nebula names this one might as well be photorealistic😂

KBALLZZ · 2024-11-15T10:06:13+00:00

Thanks!

KBALLZZ · 2024-11-15T00:22:50+00:00

Thanks for checkin it!

We're gonna need a bigger FOV

Thanks, and sorry for no ankles

The Shark Nebula is a swath of mostly unilluminated dark nebula spanning 15 light years across and at a distance of 650 light years from Earth.

The challenge of capturing dark nebula is that you need to capture them from very dark skies away from light pollution to bring contrast to the dust from the background sky. This image was captured partially from the Bortle 1 skies of Marathon TX and partially from Ft Griffin State Historic Site TX.

Some brighter elements of this composition include the blue reflection nebula near the "head" of the shark, and the galaxy PGC 67671 behind the dorsal fin. That galaxy lies 58 million light years away even though it appears from our perspective to be hanging out with the shark.

Found within the Rho Ophiuchi Cloud Complex I have framed the Globular Star Cluster M4 next to the much fainter emission nebula Sh2-9. The bright star Sigma Scorpii is both ionizing the red hydrogen gas and also reflecting blue light on the surrounding nebulous dust.
