This is the Rosette Nebula (NGC 2237). This nebula is 5,219 light years away from earth with an approximate radius of 65 light years. Image is comprised of approximately 18 images at 4 minute exposure with a combination of 20 dark frames, 20 bias frames, 20 flat frames, and 20 dark bias frames.

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.

Originally captured on 03.06.2020, I thought I had significant light pollution and lost the image. Having more experience doing post processing, I was able to pull this out. Very proud of it considering I am still new to the hobby
Two known nearby Deep Sky Objects (DSOs). "Eagle" representing the dark region of M16 near the center. Another nickname for the "Swan", "Omega", was given due to the early discovery sketches resembling the last alphabet of the Greek letter.
This is a SHO (Hubble Palette combination). The red uses the Ionized Sulfur (SII) filter, the green uses the Hydrogen Alpha (Ha) filter, and the blue uses the Doubly Ionized Oxygen (OIII) filter. Stack of 13 x 600 seconds for SII and OIII, and 12 x 600 seconds for Ha. Total integration of 6 hours and 20 minutes.

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.

Les dejo un segundo procesado de esta nebulosa que fotografié hace unas semanas y luego de aprender nuevas técnicas creo que quedó mucho mejor de lo que pude hacer la primera vez sin tanto conocimiento. Sigo practicando para llegar a aprovechar cada sesión al máximo.
Esta es NGC 5189, una hermosa nebulosa planetaria espiral que se encuentra a 3000 años luz de la tierra.

This is a crop and reprocess of the Heart Nebula, roughly 6 panels of my 15-panel mosaic.
I reprocessed to better balance the ionized hydrogen (shades of gold) and oxygen (shades of blue) and used a lighter touch in Topaz denoising.
