NGC90 and very deep field


https://i.ibb.co/xStVkK1/tentative-3-resized.png

This photo is a 110+ hours effort to uncover a rarely imaged area of the space. Thanks to the integration time hundreds of thousands of very distant fuzzies popped out, an initial annotation showed the most distant object to be the quasar SDSS J002147.97+221101.3 with a red shift of 2.979, which should place it at around 11B LY distance (in light travel terms) or 18B LY in actual terms. Pretty sure there is something even farther away in there as i barely managed to annotate 1% of the object

What an amazing image of the area around Arp 65! You should try Abell 1367 in Leo.

NGC 7635 and its companions

Dive into the heart of the Milky Way, halfway between Cassiopeia and Cepheus. Here, you'll find a multitude of celestial objects, such as the Bubble Nebula (NGC 7635) and the Lobster Claw Nebula (SH2-157), but there are other emission nebulae as well. In the center at the bottom, you can observe NGC 7538, SH2-159 in the middle, and one as large as the claw, SH2-161, to the right of the image. That's a total of five emission nebulae, not to mention a large number of both bright and dark nebulae. Additionally, there are two open clusters, one of which is part of the Messier catalog: M52, in the upper right. The other, more modest one, NGC 7510, can be found in the lower left. Unlike the other objects mentioned in the Cassiopeia constellation, this little one belongs to Cepheus.

This image was created over five nights, from October 7th to 11th, 2023, accumulating a total of 45 hours of exposure time. The equipment used includes an ASI 1600mm Pro camera coupled with an Askar 400 telescope and its x0.7 reducer, which shortens the focal length to 280mm with an aperture of F/3.9. These five nights were spent in my garden in Le Cannet-des-Maures, southeastern France, under a Bortle 5 sky.

I chose the SHO palette to highlight the different layers of hydrogen, sulfur, and oxygen present in this part of the sky. It's a palette that I particularly appreciate because it blends colors ranging from brick red to blue, with hints of yellow and green.

I hope you enjoy it, and clear skies!

The rotten fish nebula

LDN1251 is one of the numerous dark nebula in Cepheus.
It is around 1000 light years away.
Such dusty molecular clouds are known to be places of star formation.



This image is a collaboration of Julien Dufour, Christophe Vergnes & Nicolas Martino :

At first there should have been 2 images, the one of Nico & Christophe (FSQ / 2400MC) and the one of Julien (Epsilon 160ED / 2600MM).
But through a chance discussion, Christophe had the idea of this collaboration. The idea was to benefit from the colors of the 2400MC and the luminance and stars of the Epsilon.
Christophe captured the color layer from his backyard, Julien captured the luminance and the color layer of the stars in Aisne and Nièvre.

IC 63 - The Ghost of Cassiopeia.

About 550 light-years away in the constellation of Cassiopeia lies IC 63, a stunning and slightly eerie nebula. Also known as "The Ghost of Cassiopeia", IC 63 is being shaped by radiation from a nearby unpredictably variable star, Gamma Cassiopeiae, which is slowly eroding away the ghostly cloud of dust and gas.

Shot on a ZWO ASI 2600 MC Duo with a TS Optics 90mm CF APO Refractor telescope. I used .030 welding wire stuck on the front of the lens to make the star spikes that are commonly associated with newtonian style reflectors.

This was imaged over multiple nights, resulting in 24hrs 45mins worth of integration time. For one of the nights I used my Optolong L-Extreme filter to gather more Ha data.

Thanks for looking!

The Hidden Beauty Behind Messier 15

Here is an image I would like to submit for APOD! I think it’s a very unique image that shows the M15 cluster like never seen before.

I imaged the M15 cluster for three hours at first and realized there was IFN around it. I did research on Astrobin and other sites to find what the best picture of M15 with IFN was, and there was just a few with only a bit of IFN visible.

I decided to spend 14 hours on it from Bortle 2 skies to reveal as much gas and IFN as possible. To my surprise, there was also Hydrogen Alpha visible going from the cluster itself towards the left! All of these colors are real and I made sure to use a very natural workflow when processing the image.

I like working on these types of image because it shows that even the most “boring” or “overlooked” clusters can hide something incredible.

I hope you like it!

Arrow of the Hunter (Meteor Over the Black Desert)


The Orionid Meteor Shower produced the great meteor that is penetrating the night sky and arcing across the constellation of Orion like a spear or arrow.

Additionally, a satellite route is visible next to the comet.

Sunspot Mirage, Green Flash and Inversion Layer
Photo description:
During sunset, a distinct green flash occurs when the Sun passes through the temperature inversion layer. If there are sunspots at this time, a sunspot mirage will appear. On January 30, 2023, while witnessing a sunset on Taiwan's Hehuan Mountain, the sunspot mirage and green flash appeared in succession. After comparing these photos side by side, it's clear that the sunspot mirage and green flash both appear on the same horizontal line. These horizontal lines represent the position of the temperature inversion layer in the atmosphere. Equipment Details:Canon R7 + 600mm Lens
Post-processing Details: Use PowerPoint to compare 6 photos side by side.

Composition with 17 phases of the annular solar eclipse on October 14, 2023.

Photo Description:
The images were captured at the Brazilian Space Agency event at Natal Air Base (BANT) in Rio Grande do Norte, Brazil. The images were captured between the times of 3:29 pm and 5:13 pm (GMT-3). The equipment used was a 50mm Guider with tripod, planetary camera and a baader filter, as well as other accessories that helped maintain a good camera temperature and a tripod to support all the equipment. A 3D-made adapter was used to securely fit the filter. After recording in capture software, the frames were extracted to create the composition. In Brazil we had a historic and very important day for Brazilian astronomy.

I have been excited to image these “tiny” galaxies for years, and finally got a chance with an exceptional night, galaxies high overhead, no moon, no wind. And I am delighted with the outcome. What a treat in a sometimes punishing hobby.

Auroras in Iceland

1-Photograph taken a few kilometers north of Nesjahverfi, southeast Iceland on 10/13/2023. The auroras appeared very visibly and with a predominant reddish color captured by the camera. Green/yellow is produced at an energetic wavelength of 557.7 nm, while the redder and purple color is produced by a less frequent wavelength at 630.0 nm.

Although the depth was only 12.4% for my location (Athens, Greece), I was very much looking forward to pursuing this eclipse as is the case for all eclipses. Regrettably, cirrus clouds were coming and going and my best catch occurred 15 minutes before the partial eclipse maximum.
