NGC4027

This one is rarely imaged although its pretty close to the Antenna NGC4038.

I found it when I did some test images with the widefield H400 in February.

Image Description and Details : Sh2-284 is a very large emission nebula about 17,000 light years from us in an outer arm of our galaxy. As with a number of emission nebulas like it, its central region contains an open cluster of massive, young, hot stars whose stellar winds are clearing out the center and creating a bubble or cave-like structure while creating pillars and cometary globules at the edges. Once such pillar in Sh2-284 (on the right) looks like an index finger pointing at the center of the nebula in a "We're Number 1" sort of way.

Sun disc on April 15th, 2023.

How frustrating when the clouds followed the sun for an hour after everything is set up and ready to go....

With so many previous practices, I think I have figured out a way to produce high-resolution Solar disc images. Originally I have to produce a higher-resolution image using 2 panels mosaic with 2X Barlow. However realizing that the magnification of a Barlow actually depends on the distance from the Barlow lens to the camera sensor, I decided to put the Barlow lens closer to the sensor by screwing it directly onto the camera. The solar disc is not fitting perfectly in a single frame of my Apollo M-Max. My next project idea will be using this configuration to make a good quality timelapse.

Image Description and Details : The constellation Crux, very present in the sky of the Southern Hemisphere, is the smallest of the 88 constellations (IAU), it served as an important point of reference for the location of the South direction, in the period of the great navigations, from the 15th century onwards.

The pole rotation records show the beautiful star trails, but hide the wonderful constellations, stars and planets that appear as curved lines. In this photo, the brightest star trails predominantly around the South Celestial Pole (SCP) appear, but also the beautiful constellations and stars that would otherwise be hidden. In the center, a part of one of the original photos was inserted to highlight the constellations Crux and Centaurus (Alpha and Beta) present during the capture, showing their star trails, both the upper part (of the sky) and the lower part ( of the lake), mirrored in a beautiful and serene lake.

On the right side of the photo, the star Antares, records a beautiful yellowish star trail.
At the bottom of the original photo (center) are the Crux and Centaurus constellation mirrored in the lake, with dashed lines (left), pointing to the region near the South Celestial Pole in mirrored form, recording a basic technique to find the region near the SCP.

The 1,136 photos that make up this record (over six and a half hours of capture) were taken in the Midwest of Brazil, during the 13th Brazilian Astrophotography Meeting (13th EBA – Encontro Brasileiro de Astrofotografia), in July 2022.

Equipment: Canon EOS REBEL T4i camera, with power bank, Bower 14mm ED AS IF UMC 2.8 lens, battery-powered lens heater and Manfrotto Fixed Tripod. Programs: Startrails, IrfanView 64 and Affinity Photo.

Image Description and Details : Vela Widefield!
Call me a widefield junkie if you will…. the wider the better !! And if it is in the Southern Hemisphere, then that’s the icing on the cake. This 2 panel mosaic spans about 6 degrees across a widefield region in the constellation of Vela. The blue gas clouds are from the remnants of the Vela Supernova and one can see NGC 2736, or the Pencil Nebula glow brightly on the right of the frame. The nebula's shape suggests that it is part of a supernova shock wave that has encountered a region of dense gas. It is this interaction that causes the nebula to glow and form ripples. RCW 38 dominates the center of the frame and is an HII region with dark clouds enshrouding recently formed stars. The gases and clouds come together to form a rich tapestry of glowing reds and dark blacks. Also seen in the image are RCW 39 and 40 amongst lots of other fine details…..

"Towards Orion"

Befor you draw your conclusions, let me explain this image: The sky and foreground were captured back to back at the same focal length and with the same equipment from a single tripod position.

The camera position was roughly 2 miles away from the mountain station, and the telescope/camera combination has an extremely narrow field of view of only 1.5° x 2°. The resulting telephoto compression makes the otherwise tiny Orion Nebula appear huge.

Two years ago, I had already captured a similar deepscape, but I was never really satisfied with it. The problem was lacking data for my sky, especially in the green channel, as clouds moved in towards the end of the imaging session.

Of course, I could have recaptured the missing data or the entire Orion Nebula from a different place, but that's not my style. After waiting two years for an opportunity to reshoot the image, I finally got my chance this February.

The weather this time was perfect, which made capturing the sky pretty straightforward, but otherwise, the conditions were still as demanding as 2 years ago.

Getting the foreground in focus with a monochrome micro 4/3rd astro-cam and RGB filters through a 500mm f/5.6 telescope is a real pain. Furthermore, snowcats grooming the slopes caused constantly changing, extremely bright illumination. Considering this, I am quite happy that I was able to capture a usable foreground.

Image Description and Details : I first attempted this tiny planetary nebula back in 2019.

I decided to attempt it again by piling on more data, adding in RGB for star color and even tried drizzling the data at 3x instead of 2x. I am much happier with the results. It still took a lot of massaging of the data to get it where I wanted it to be, however.

NGC 2371 is a planetary nebula, the glowing remains of a Sun-like star. The remnant star visible at the centre of NGC 2371 is the super-hot core of the former red giant, now stripped of its outer layers. Its surface temperature is a scorching 240,000 degrees Fahrenheit. NGC 2371 lies about 4,300 light-years away in the constellation Gemini. It is one of the largest planetary nebulas known, measuring roughly three light-years across.

It confused astronomers when it was first studied. Rather than being classified as a single object, it was instead recorded as two objects, named NGC 2371 and NGC 2372, owing to its symmetrical lobed structure.

It is filled with dense knots of gas, fast-moving jets that appear to be changing direction over time, and expanding clouds of material streaming outwards on diametrically opposite sides of the remnant star.

Image Description

This is an image of M82, also known as the Cigar Galaxy. It is a starburst galaxy about 12 million light years away in the constellation Ursa Major. It is about five times more luminous than the Milky Way and its central region is about one hundred times more luminous. The starburst activity is thought to have been triggered by interaction with neighboring galaxy M81.

Image Description and Details : Strottner-Drechsler 163 / PNG 184.4+05.4

This candidate planetary nebula was discovered by our team in August 2022.
StDr 163 in the constellation Gemini is without doubt one of the most beautiful objects in the StDr catalogue.
The remarkable aspect of this nebula is that we can literally watch the structure expand.
The hot star in the centre is surrounded by a constantly growing envelope of ionised oxygen (OIII).
Gently, the blue OIII core breaks through the red cocoon of ionised hydrogen (H-alpha).
It is not known whether the reddish halo area around the nebula, which resembles two wings, belongs to the object itself, or whether it is interstellar material that is ionised and excited to glow by the potential white dwarf in the centre.
Discovery by my amazing friends Xavier Strottner and Marcel Drechsler. Data capture by myself and Sven Eklund from our remote observatories in Spain. Image processing by Marcel Drechsler.

Image Description and Details : The supermassive black hole powering M87's core has a mass about 6.5 billion times that of the Sun and generates two jets of plasma in opposite directions that span thousands of light-years. The jet oriented towards the Earth is visible and appears blue / light blue while the other is extremely weak and is not visible. The great luminosity and blue tint of the jet are due to the relativistic effect called "relativistic beaming" or "Doppler boosting" which occurs because particles oriented towards our line of sight are accelerated by the black hole up to 99% of the speed of light and simultaneously emit radiation.

Image Description and Details : On the right of the picture, IC 443, or SNR G189.0+03.0, is a supernova remnant located in the constellation of Gemini, with a large angular size (45 minutes of arc, or one and a half times the apparent diameter of the Moon), and quite luminous both in X and in radio. Its distance is rather uncertain and is estimated to be between 2800 and 8000 light years, while its age varies between 3000 and 30 000 years.

The supernova afterglow IC443, with a golden colour indicates that the Ha and SII are strongly interacting, and OIII surrounds a large part of the object. OIII has a slightly faster expansion rate.

On the left of the picture, the emission nebula SH2-249, which is not in the same plane as Ic 443. It is at about 5200 AL There is also a very small nebula in the field.

Image Description and Details : Sunspots are temporary phenomena that occur on the surface of the Sun, which appear as dark spots and are regions of reduced temperature relative to the regions around it.
In the week of February 27, 2023, the Sun had several sunspots, with the highlight of AR 3234, a very beautiful group of sunspots, with a beautiful sunspot standing out, with many details.
The group of sunspots AR 3237, on the other hand, helped the composition of the photo, highlighting with beautiful groups of sunspots.
The photo was captured on the same morning of February 27, 2023, in 02 different telescopes (with an ASI290MM camera + Baader white light filter + Baader Solar Continuum Filter): an 11” SCT (C11 - in the details with photos on the right) and an APO 80mm composing a mosaic of 02 panels in full disk, defining the context of the location of the large groups of highlighted sunspots.
Its yellowish coloring is artificial, as the capture is made with a monochromatic camera with a white light filter, enhancing these beautiful images.
This composition with full disk (on the left) and large sunspots highlighted (on the right) presents a beautiful scenario of that beautiful moment.
