This is my first Orion Nebula of the season. I used my smaller 6" Newton to capture it. In the next weeks i try to use the 10" to get a detailed picture of the center of the nebula.

This is my first time using the H-Alpha Version of my Canon 60Da. Great to see it captures the H-Alpha lines so well. Barnard 33 is one of the most amazing objects is captured so far, I hope you enjoy the picture !

Leo Triplet (M65, M66, NGC3628), 03/17/2021
Galaxy season is here. In Spring most of the nebulas set too early to photograph so attention turns to distant and dim galaxies. For my current setup this is unfortunate because I have wrong field of view for tiny galaxies. But a YouTube channel I watch (Chuck’s Astrophotography) did this group using the same telescope I have so I gave it a go. Thanks Chuck! I did spend a lot of time on this so I would have enough detail to crop it in a bit. So, I give you the Leo Triplet, unsurprisingly found in the constellation Leo. These gravitationally bound galaxies are approximately 35 million lights years from you.

A comet streaks across a dark night sky, dotted with distant stars. No specific person is identifiable in the image, but the image shows a celestial event, likely captured by an amateur astronomer or astrophotographer. The comet's tail is visible, indicating its movement through space. The image's purpose is likely to document and share the observation of this astronomical phenomenon.

A Whisper from the Long Night: Comet 24P/Schaumasse
On December 30, 2026, beneath the still and patient sky of Desert Bloom Observatory, Comet 24P/Schaumasse revealed itself not as a spectacle, but as a whisper. At a modest magnitude of 9.4, its light arrived faint and restrained, a reminder that not all celestial travelers announce their presence with grandeur. Ten stacked exposures of 600 seconds were required to gather enough ancient photons to form this image—each one a fragment of sunlight reflected by ice and dust released as the comet slowly warms. The absence of a pronounced tail is not a failure of vision, but a lesson in physics: low activity, distance from the Sun, and limited gas production all conspire to keep its signature subtle. This image teaches patience—how astronomy rewards those who listen carefully to the dark, where even the quietest messengers still carry the story of the early solar system.

Elephant's Trunk Nebula is a nebula, a structure of gas and dust, located in the constellation Cepheus. It belongs to a lot larger emission nebula IC 1396 (the entire red object in the image). The elephant's trunk itself is only a small part (in the middle of the crop in the second image), which really looks like a curled elephant's trunk. The whole nebula is ionized by a massive star in the center and is home to very young stars. It lies at a distance of 2400 light years and has a size of 6 full moons in the night sky!
The obviously red star at the edge of the nebula is called Herschel's Garnet Star or Erakis. It was noted by William Heschel, who described it as "a very fine deep garnet colour, such as the periodical star Omicron Ceti (variable star in Cetus)". It is one of the largest known stars with a radius of around 1.2 billion km and is expected to explode "soon" like a supernova and become a black hole.
There is also a part of Sh2-129 (the Squid Nebula) in the lower right corner.
I took this image in August with my modified Canon EOS 1300D and CLS filter. It was made from only less than two hours because of a short night and clouds, but it still looks pretty good.

The Cygnus constellation is full of various hydrogen nebulae, but they are very faint in visible wavelengths, so it's very difficult to see them with your eyes in a telescope. However, when you use a modified camera, which lets the infrared wavelengths go through, and you take a long exposure, the complicated nebulae will appear.
One of the brightest nebulae in Cygnus (which is even visible in big telescopes) is called the Crescent Nebula and lies roughly in the center of my image. In the upper right corner, there you can also see Tulipan nebula (or Sh2-101), which is fainter than Crescent and lies at a distance of 6000 light years, which is about 1300 ly further than Crescent. Another interesting region lies in the bottom left corner. It's a Sadr region, which is named after a Sadr star, which is the brightest star in the picture and lies 1800 light years from Earth.
This image was taken on the 7th of July with my modified camera Canon EOS 1300D and CLS filter, which lets only H-alpha and OIII parts of the spectrum pass through and that's why, it can capture such beautiful details in the nebulae. The result amazed me. It is created only from 3 hours of data, which isn't pretty much for this region. Truly happy with this progress and looking forward to the next tries.
