EGB 4 (a nebula discovered by Ellis, Grayson, & Bond in 1984) is NOT a comet, despite it's comet-like appearance. It is an emission nebula surrounding a catacylismic binary star system called BZ Cam in the constellation of Camelopardis.

It has an unusual bow-shock structure as BZ Cam (with it's associated wind) moves through the interstellar medium, similar to the bow wave in front of a ship that is moving through water.

BZ Cam is believed to be a white dwarf star that is accreting mass from an accompanying main-sequence star of 0.3-0.4 solar masses.
It is around 2,500 light years away, and has a space velocity of 125 km/second.
I can only find one previous image of EGB 4 online, a NASA APOD from 2000, so I believe this could be the first amateaur image and thefirst colour image.
Yes it's incredibly faint!

NGC 6726/6727 and IC 4812 are blue reflection nebulae, where bright stars are embedded in a large cloud of dust which reflects the blue light of the stars. NGC 6729 is a butterfly-shaped emission/reflection object that is a variable nebula, powered by the irregular variable star, R Coronae Australis (R CrA). R CrA was discovered about 100 years ago. HH objects are shown as delicate, small arcs of glowing gas.

This is the comet c / 2017 T2 Panstarrs, imaged thru its passage of sh2- 205.

Based on the absolute magnitude published for this comet by the British Astronomical Association's Comet Section, it is estimate that it may be around mag 7 at perihelion.

Comet C/2017 T2 (PANSTARRS) will make its closest approach to the Sun, at a distance of 1.61 AU.

From BAA….C/2017 T2 (PANSTARRS) was discovered at 20th magnitude in 2017 September when it was it was 9.3 au from the Sun. It is heading for a perihelion at q=1.6 au in early 2020 May. The comet is currently in conjunction but it was apparently brightening rapidly when last seen in April. It should become visible from the UK in mid July very low in the morning sky as it moves slowly NE in Taurus. By then it will be 3.8 au from the Sun and 4.5 au from the Earth. It moves higher in the sky and will be visible throughout the autumn, winter and spring as a circumpolar object and it remains well placed in Ursa Major at perihelion. Magnitude estimates through the late summer and autumn should help to constrain the lightcurve.

Image Description and Details : Here is my first object captured in 2020.
This is the dolphin head nebula, Cataloged Sharpless SH 2-308, it is about 5,200 light-years from home towards the constellation of the Big Dog.
The massive star (Wolf-Rayet type) that created the bubble is the bright star located near the center of the nebula.
It generates a powerful radiation which drives out the gas around thus creating a giant bubble.

The Large Magellanic Cloud (LMC) is a satellite galaxy of the Milky Way. At a distance of about 50 kiloparsecs. The LMC is classified as a Magellanic spiral. It contains a stellar bar that is geometrically off-center, suggesting that it was a barred dwarf spiral galaxy.
The picture was taken in the remote observatory of ChileScope with telelens nikon 200 f2 and a camera fli 16200.
The set was HaLRGB and was 40min of Ha and 15 min in LRGB.

NGC 1365 taken at Martin Pugh Astrophotography in Australia.

NGC 1365 is barred spiral galaxy in the Fornax cluster. Within the larger long bar stretching across the center of the galaxy appears to be a smaller bar that comprises the core, with an apparent size of about 50″ × 40″.

This second bar is more prominent in infrared images of the central region of the galaxy, and likely arises from a combination of dynamical instabilities of stellar orbits in the region, along with gravity, density waves, and the overall rotation of the disc. The inner bar structure likely rotates as a whole more rapidly than the larger long bar, creating the diagonal shape seen in images. The spiral arms extend in a wide curve north and south from the ends of the east-west bar and form an almost ring like Z-shaped halo.

Astronomers think NGC 1365's prominent bar plays a crucial role in the galaxy's evolution, drawing gas and dust into a star-forming maelstrom and ultimately feeding material into the central black hole.

NGC 1365, including its two outer spiral arms, spreads over around 200,000 light-years. Different parts of the galaxy take different times to make a full rotation around the core of the galaxy, with the outer parts of the bar completing one circuit in about 350 million years. NGC 1365 and other galaxies of its type have come to more prominence in recent years with new observations indicating that the Milky Way could also be a barred spiral galaxy. Such galaxies are quite common — two thirds of spiral galaxies are barred according to recent estimates, and studying others can help astronomers understand our own galactic home.

NGC 1672 is a barred spiral galaxy located in the constellation Dorado. It was originally thought to be a member of the Dorado Group, however, this membership was later rejected.
NGC 1672 has a large bar which is estimated to measure around 20 kpc. It has very strong radio emissions emanating from its nucleus, bar, and the inner portion of the spiral arm region. The nucleus is Seyfert type 2 and is engulfed by a starburst region. The strongest polarized emissions come from the northeastern region which is upstream from its dust lanes. Magnetic field lines are at large angles with respect to the bar and turn smoothly to the center.

It was taken with a 36.8 cm F9 Ritchey Chretien telescope using a SBIG STXL16200 CCD camera. The exposure is a LHaRGB image with about 9 hours total imaging time.
