I'm still blown away by this image; it's so much better than the one I was able to capture two years ago. All I had to do was throw a bit more money at it! usa.gif

Wow, thats so cool, was it a 59 second picture or 59 1 second frames or something of the like?

Basically all im asking is if you did any stacking.

Awesome!  Tracking looks good enough to try about 100 x 59 sec images stacked with calibration frames. That’s when the real WOW begins.  Although, you may want to back off a bit down to 300-400mm focal length.  This will give you more light for the same time and less sensitivity to tracking errors.

Fun fact about Orion I didn't know.  I asked a chat program why the Orion Nebula has such a bright core.  This is what it told me:

 

 

The Orion Nebula is a diffuse nebula situated in the Milky Way, being south of Orion’s Belt in the constellation of Orion. It is one of the brightest nebulae and is visible to the naked eye in the night sky with apparent magnitude 4.0. The nebula contains a very young open cluster, known as the Trapezium Cluster due to the asterism of its primary four stars within a diameter of 1.5 light years. Two of these can be resolved into their component binary systems on nights with good seeing, giving a total of six stars 1. The Trapezium stars are only a few hundred thousand years old, about 15-30 times the mass of our Sun, and so hot and bright that they’re responsible for illuminating the entire Orion Nebula 2. Ultraviolet radiation produced by the Trapezium stars is heating the surrounding gas, making it fluoresce like the glowing gas in a neon bulb. These massive stars are also sculpting the nebula 3. The peak surface brightness of the central region of the nebula is about 17 Mag/arcsec 2 (about 14 milli nits) and the outer bluish glow has a peak surface brightness of 21.3 Mag/arcsec 2 (about 0.27 millinits)

Very cool, it’s fun huh… laugh.gif

 

Unfortunately money makes a big difference in this game… and it never stops helping, even the JWST isn’t good enough. 
 

It’s fun to make due with what you have though, and see how far you can push it…

I made this little 90 second project last year mostly by accident to get at the trapezium core stars. 10x 10 second subs… Crazy how bright they are… It’s so so hard to keep the details in the core and not blow it out.

Rogers92, Looks like you captured one of the many satellites that pass through that area. Good photo.

There's a big difference between your f/2 and the OP's f/6.3—you had almost 10× the flux…plus another 1.7× the integration time (so 17× better SNR to start with)!

Hey sorry for the delayed response! It’s a single exposure. No stacking involved.

That is fascinating! When I talk to ChatGPT, it just tells me that 2+2=5 LOL

Thank you! I actually think I captured two satellites. One directly below, and one on the top left shoulder of the nebula.
