In this image taken at Grand Mesa Observatory, www.grandmesaobservatory.com. Comet C/2017 T2 takes another photo op as it passes by Galaxy Messier 106 (M106) in the night sky this past Tuesday night, June 23, 2020.
Discovered on Oct. 2, 2017 by the PanSTARRS sky survey, this comet has put on quite the show over the past couple months. Here it's seen passing within a degree from M106, a very close and beautiful event. While they might look really close to each other in this image If you were travelling at the speed of light it would take between 22 to 25 million light-years to reach M106 but only 14.5 light-minutes to reach Comet C/2017 T2.
Messier 106 is an intermediate spiral galaxy located in the constellation Canes Venatici and It’s is one of the largest and brightest nearby galaxies similar in size and luminosity to the Andromeda Galaxy.

This is my target for Astro fest but I had to take it well before hand so that the target shows up on screen as a quality image from the build up of shots. This is a very large part of the Large Magellanic Cloud.
You are looking at two night worth of images at 200 Sec while I was after a third night clouds well and truly got in the way. This is two nights or 170 images worth of shots or 16 hours worth of data.
I have pulled all my gear ready to put in my car ready to set up on the site and run contactless from outside the tent on the field a Curtin University. There will be some 50 Telescopes on the field so viewing and some photographic like mine.

De SkySafari:
#M57, se conoce como la Nebulosa del Anillo. Es una nebulosa planetaria, que son restos de estrellas similares al sol que han expulsado sus capas externas, dejando estrellas enanas blancas del tamaño de planetas en sus centros.
Fue descubierta en 1779 por el astrónomo francés Antoine Darquier en 1779. Charles Messier la incluyó en su famoso catálogo unos meses después. William Herschel, quien descubrió el planeta Urano, fue quien denominó este tipo de objetos como nebulosas planetarias al creer que se relacionaban con planetas. Herschel la describió como una nebulosa perforada, o un anillo de estrellas; también identificó algunas de las estrellas superpuestas e identificó correctamente que no pertenecían a la nebulosa.
En 1800 se descubrió la estrella central y en 1864 se analizó el espectro, encontrando que este tipo de nebulosas no está compuesto por estrellas, al encontrar que las líneas de emisión coincidían con gases ionizados brillantes: oxígeno en la parte central (azulado) e hidrógeno y nitrógeno en la parte externa (rojizo).
Se estima que el diámetro de M57 es de 0.8 años luz y el de la aureola alrededor es de 2.4 años luz. Su edad se estima entre 6000 y 8000 años (cuando se desarrollaron las civilizaciones de los sumerios, el Antiguo Egipto y el Valle del Indo).
Las nebulosas planetarias se forman después de que estrellas de masa mediana o baja, como el Sol, agotan el combustible de hidrógeno en sus núcleos. En este punto, las capas exteriores de las estrellas se expanden, y se convierten en gigantes rojas. La parte externa gaseosa en expansión forma la nebulosa planetaria, mientras que el núcleo estelar colapsa para convertirse en una enana blanca, iluminando la nebulosa con energía ultravioleta de su superficie extremadamente caliente.
La estrella central que ilumina M 57 contiene aproximadamente 1,2 masas solares. Esta enana blanca del tamaño de un planeta similar a la tierra, es más tenue que el Sol.

The Pelican Nebula (also known as IC 5070 and IC 5067[1]) is an H II region associated with the North America Nebula in the constellation Cygnus. The gaseous contortions of this emission nebula bear a resemblance to a pelican, giving rise to its name.[1] The Pelican Nebula is located nearby first magnitude star Deneb, and is divided from its more prominent neighbour, the North America Nebula, by a molecular cloud filled with dark dust.
The Pelican is much studied because it has a particularly active mix of star formation and evolving gas clouds. The light from young energetic stars is slowly transforming cold gas to hot and causing an ionization front gradually to advance outward. Particularly dense filaments of cold gas are seen to still remain, and among these are found two jets emitted from the Herbig–Haro object 555.[1] Millions of years from now this nebula might no longer be known as the Pelican, as the balance and placement of stars and gas will leave something that appears completely different.

In this image Comet C/2020 R4 (ATLAS) cruises by the Whale Galaxy NGC 4631 and the Hockey Stick Galaxies NGC 4656 & 4657 from our perspective here on Earth. This image was captured at Grand Mesa Observatory and processed by Terry Hancock and Tom Masterson.
Using two telescope systems last week this image was captured over two nights, 5/5 and 5/6. The first night, Wednesday 5/5 we used System 1 which has a Takahashi 130 telescope capturing images with the monochrome QHY 600 and System 4 where a Takahashi E180 telescope is used and images are captured on a QHY410 color camera. On Thursday night 5/6 only System 1 was used, on this night we focused on capturing more data to get a better background image of the galaxies since by this time Comet C/2020 R4 had moved out of this field of view.
Total Integration Time 7.75 hours

La nebulosa Dumbbell (también conocida como Objeto Messier 27, M27 o NGC 6853) es una nebulosa planetaria en la constelación de Vulpecula, a una distancia de 1250 al.
Esta nebulosa fue la primera nebulosa planetaria descubierta, descrita por Charles Messier en 1764. Con una magnitud aparente de 7,4 y un diámetro de 8 minutos de arco, es fácil de observar con unos binoculares.
La nebulosa Dumbbell tiene una edad estimada de 3000 a 4000 años.
La nebulosa Dumbbell, a veces conocida en español como nebulosa de la Haltera (significado del término inglés dumbbell), o bien como nebulosa de la Manzana, constituye, igual que la célebre M57, un ejemplo de nebulosa planetaria: la envoltura expulsada por una estrella moribunda. Esta fase en la muerte de una estrella no dura demasiado tiempo, por lo cual no hay una gran cantidad de nebulosas en el firmamento. Pasados 50 000 años, simplemente se disipan en el espacio.
Se estima la distancia a la nebulosa de unos 1000 años luz, lo cual implicaría unas dimensiones de entre 2 y 3 años luz para este objeto: se trataría de una de las mayores nebulosas planetarias conocidas

The North America Nebula, NGC 7000, is an emission nebula in the constellation Cygnus. Above is the Pelican Nebula (enlarged on the 2nd image). Together the area of this nebula reaches 5 full moons across and can be seen with the unaided eye in a dark sky location.
This target was shot with using a high speed, wide field 400mm telescope coupled with a 26 Megapixel cooled camera from my light polluted backyard.

The Lagoon Nebula (catalogued as Messier 8 or M8, NGC 6523, Sharpless 25, RCW 146, and Gum 72) is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and as an H II region. The Lagoon Nebula is estimated to be between 4,000–6,000 light-years away from the Earth. In the sky of Earth, it spans 90' by 40', which translates to an actual dimension of 110 by 50 light years. Like many nebulae, it appears pink in time-exposure color photos but is gray to the eye peering through binoculars or a telescope, human vision having poor color sensitivity at low light levels. The nebula contains a number of Bok globules (dark, collapsing clouds of protostellar material), the most prominent of which have been catalogued by E. E. Barnard as B88, B89 and B296. It also includes a funnel-like or tornado-like structure caused by a hot O-type star that emanates ultraviolet light, heating and ionizing gases on the surface of the nebula. The Lagoon Nebula also contains at its centre a structure known as the Hourglass Nebula (so named by John Herschel), which should not be confused with the better known Engraved Hourglass Nebula in the constellation of Musca. In 2006, four Herbig–Haro objects were detected within the Hourglass, providing direct evidence of active star formation by accretion within it. (Explore Scientific ED80, Skywatcher HEQ5, ZWO ASI2600MC-Pro, Radian Triad Ultra Narrowband Filter, N.I.N.A., 100m integration).
The Rosette Nebula is in the Constellation of Monoceros approximately 5000 Light years from earth.
