Best 50% of 60 hours from B4

[steep geyser]

Close to 30 hours of oversampled space.

IMX 571 OSC and Mono combined, about 3 hours of Lum, 5:40 of RGB, 11 hr of Ha and the rest put into O3 and IR.

cuuute

Too oversharpened and you can increase the background brightness a bit to hide some of noise and artificat basically you pushed the data too much

[covert seal]

Very nice

[steep geyser]

I agree on the background of the wide version, it is a bit dark.
The galaxy is quite soft though, apart from the center and the dust lanes to the left. That is actually not sharpening artifacts but rather the IR data used to lower the glow. It makes everything in the glow more contrasty- revealing the central clusters and dust lanes.

Idk the core looks a bit off

A little too much texture

Idk could just be me

[pure narwhal]

you are too used to smooth images

[sharp surge]

Probably but it's like a certain wierd texture idk it's hard to explain

[ivory linden]

The dust in especially the left Side is somewhat weirdly shaped
I think its a mixture of the dust itself, the contrast and the sampling of the Data which makes it Look weird

[dusky kite]

what telescope did you use?

[sharp surge]

Bresser Messier 203D on Neq 6 Pro

Nice thx

Red shifted galaxy clusters

[dusky kite]

Wait is it

Hi. THe red shifted galaxies are the smaller faint fuzzie dots in ourange color. They look like stars but many of them are galaxies that look redder then they really are because of the red shift (light spectrum gets shifted towards the red because of the universe expanding (If I remember correctly).

[dusky kite]

Red shift can be due to expansion or relativistic Doppler effect , but nice if that’s actually the expansion red shift I’m impressed. How far do you expect them to be away? I always thought the red shift was a tiny barely measurable quantity and not visible in images.

[dusky kite]

That’s awesome, also those galaxies appear to be warped by a gravitational lens a bit if I’m not mistaken?

[ivory linden]

Iirc they are about 3 Billion lightyears away from us
Also the blue dot under the Side on-galaxy to the left is Not a star but an x-ray pulsar

[steep geyser]

Those are probably billions of lightyears away.

[steep geyser]

Interesting! I did not know that!

[ivory linden]

I saw it in a Video recently and wanted to confirm it, but havent been able to find sources
Pickles helped me to identify the Pulsar tho, i thought it was a Quasar at first

[dusky kite]

Damn that’s amazing

Furthest Galaxy I could make visible in my 180mm fl refractor was like 600m lightyears

[ivory linden]

I think thats also pretty good tbh

[dusky kite]

yeah i only have 40mm of aparture its hard

but i will get a 6" newtonian with 750mm Focallength next week

just need a mount for it then 😅

but i would theoretically get below 1" of resolution that way
