Amazing wide field with the molecular clouds around and inside the Pleiades!

 

Thank you so much for sharing,

Amazing Pleiades surrounded by IFN.
One observation - looking at histogram in AB is it too blue, more red?

Incredible. Bortle 1 is the best lp filter.

Why add the diffraction spikes I have no idea...

Wow. Astrophotography gets cloying, like white sugar sprinkled on honey, but that picture is truly both a work of art and scientifically interesting.

Thanks for sharing!

Isn't that the photo lens shutter (Rokinon 135mm) causing that effect?  It's an F2 lens and he closed it to F2.8 which is recommended.

Thank you all for your kind words!

When I finished the processing I felt the image was kind of gray and I thought a little more blue + saturation will give it a good taste!

Because of Lens' shutter. I like the spikes though :)

Wow one of the most detailed I’ve seen of the region. You think you’ve seen it all, and then you see something better. Even with modest equipment, by modern standards, the bottle 1 shows how good this stuff, and our processing tech is getting.

Thanks for the clarification! I agree I think it needs a bigger step down to avoid the diffraction spikes. Never used one of these.

I don't like the spikes (personal preference), but boy do I like the image! Great job, this is truly an excellent photo! Awesome!

The lens has no shutter. It's from the aperture blades which you can adjust more open or more closed. There's one spike per blade groove. Some lenses can have more or less blades and the number of spikes is equal to how many and how well defined the blades grooves are. Adjusting the aperture can slow down or speed up the F value, but also increase or decrease the spikes.

Great info! 

 

Actually what I meant were the blades but I didn't know what it called in English "I'm an Arabic speaker" so I thought it called the shutter

Very nice image.

 

If you want to avoid the spikes from the blades, you can use step-down rings instead of the blades.

These are very cheap (these are plastic, after all), and perfectly circular.

You could for example use a step down ring 77mm to 67mm, or even 77-62

Nice image, but I think to much agresive processing distroy finally soft nebula effect.

Actually this is my softer version, below is my 1st version, more aggressive. Even though APOD shared the below one on their Instagram story, but I like the softer version more :)

The first time I ever saw the Pleiades from a Bortle 1 site it blew me away. At first I thought my eyepiece was either dirty or just fogged up, but I was seeing the reflection nebulosity directly and it was so bright I couldn’t believe it.
