The white-blue stars that populate these two clusters are part of a bigger collection known as Perseus OB1. This means that these are big, hot main secuence stars that are at least more than twice as hot as our Sun.
This pair of star clusters are called Xi Persei, and popularly known as the Double Cluster. You can see this two with your own eyes, without any aid, from a dark sky.

I managed to sneak in a first light for the AT90CFT and my HAE43EC over the weekend. Lots to learn! These pictures were taken almost on a lark, so they are a variable number of 30s frames apiece with manual focusing on the Canon SL1 taken in my severely light polluted Austin TX backyard in between clouds.

Second try at processing my IC 63 image (left). The previous one (right) had the terrible halo around Navi. This time I used H-alpha data for my luminance during processing. Less halo, more nebulosity. Definitely a better result. #astrophotography #pixinsight

Plus d’un an sans utiliser mon matériel. Bigre tout est à re apprendre ! De la mise en station aux nouveaux logiciels en passant pas le focuser, les nouveaux colliers, le mini hub, le plate solving, le guidage, les câbles égarés, et j’en passe. Bref, une cible un peu choisie au hasard vite fait… pour de la photo. Ça fonctionne !. Ouf. 35 mn ha + 8 mn en b et v. 52 Cyg et ngc 6960

#UMPlus - Colors over the Grand Canyon

https://www.universomagico.net/2023/09/colores-sobre-el-gran-canon.html

The excellent image taken by Antoine Grelin shows the Grand Canyon, a sinuous rock formation located along the Colorado River, a colorful and steep gorge carved over millions of years in northern Arizona, United States. It is located for the most part within the Grand Canyon National Park, one of the.....

Even bigger project! I spent over 31h imaging this two-panel mosaic of the Elephant Trunk nebula. This area is jam-packed with colorful emissions and strange dusty structures. Which do you like better? Foraxx + boost (first) or HOO (second)

Part 2 of the milk way timelapse from Monday at Cape Blanco. I used my widest lens to get the waves and ships in frame. You can notice the shift to blue/cooler tones which I believe is due to the moon rising out of the frame. #oregoncoast #pnw #ontheroad #astrophotography

Pelican Nebula. IC 5070

I captured two and a half additional nights of data on NGC 7822, this time with a different dual narrow-band filter that captures the Oxygen III emission line in the green and blue channels of the camera and the Sulphur II emission line on the red channel.

Combining this new data with the original data (Oxygen III and Hydrogen Alpha), I produced an SHO image where the Sulphur II, Hydrogen Alpha and Oxygen III emission lines are assigned to the the red, green and blue channels of the image respectively.

In total 13h 30m of data, 5h 5m on the Oiii+Ha filter and 8h 25m on the Oiii+Sii filter.

Additionally, here are a few I've posted before, but like Andromeda, I didn't do a great job on them the first time around so I redid them

Okay, now that I have a better understanding of how to process and tweak the images that I get, here are the other celestial objects I've tried to take images of that didn't turn out as well for various reason

#astrophotography

I've discovered a new #astrophotography foe: the roof gutter

There is no "right way" to prepare #astrophotography images. Almost every astro pic is not what your eye would see. Both because your eye isn't a camera, and because the photo was manipulated to emphasize certain details or structure.

A lot of images from scientific instruments, like JWST, are of wavelengths your eye can't even see. No one knows what a nebula is "supposed" to look like in infrared. Someone just arbitrarily decided the color table, contrast, etc.

It's an art like any other

I'm really liking #astrophotography because it's equal parts science and aesthetics.

Like, you have to be able to capture the images in the first place —which requires a lot of technical knowledge and skill— but once you've got that image, you can play with the pixels as much as you want to get something you think looks cool.

That pic of Andromeda is not what came out of the camera. I made it look the way it does, and I think that's fun
