🧵(2/2) As always, here is are a starless version of the reprocessed data to enjoy the sheer beauty of the object.

C/2025 A6 (Lemmon) was discovered as an asteroidal object with an apparent magnitude of about 21.5 by the Mount Lemmon Survey in images obtained on 3 January 2025 when it was 4.5 AU from the Sun. Consequently, precovery images by PanSTARRS dating from 12 November 2024 were found.[2] The object was found to have a very condensed coma, 2.2 arcseconds across. A short tail, two arcseconds long was found in images from 21 February 2025.[7] When first discovered the comet was expected to only brighten to apparent magnitude 10, but is now expected to brighten to apparent magnitude of about 3.5, which would make it about 400 times brighter than original expectations.[8] After being hidden in the Sun's glare during June and July as it came to solar conjunction on 2 July 2025,[9] the comet was spotted again in the morning sky, significantly brighter than predicted. On 12 August the comet had a coma about one arcminute across and an apparent magnitude of 13.9. By August 19, when the comet was 1.7 AU from the Sun, its total magnitude (nucleus+coma) was estimated to be 11, but the comet did not show an obvious tail.[10] A short spiky tail was visible in images from 25 August.[11] The future brightness of the comet is unknown, but the comet is not expected to have been in an outburst when it exited solar conjunction.

Outstanding work. Bravo. What gear did you use if I may ask ?

Good work Gordon. This target is notoriously hard to squeeze detail out of 👍

Starless version of C/2025 A6 (Lemmon), a non-periodic comet discovered by the Mount Lemmon Survey in images obtained on 3 January 2025. It has an inbound orbital period of about 1,350 years and will pass perihelion on 8 November 2025 when it will be 0.53 AU (79 million km; 49 million mi) from the Sun. This perihelion passage will reduce the orbital period to about 1,150 years. It makes its closest approach to Earth on 21 October 2025 and may be visible to the naked eye 42 degrees from the Sun after sunset. As of 12 October 2025, the comet is about apparent magnitude 5.6,[6] and is visible in binoculars about 15 degrees (approximately one and a half fists) below the cup of the Big Dipper. It is currently about 2 degrees southwest of the star Psi Ursae Majoris.

Yes indeed and in this case, it was done with a small telescope with a 61mm aperture and 300mm focal length

Starless version of NGC 7822 is a star-forming emission nebula and the "Cosmic Question Mark" nebula located in the constellation Cepheus, approximately 3,000 light-years from Earth. It's a vibrant region containing the Sharpless 171 emission region and the young Berkeley 59 star cluster, illuminated by hot, young stars that ionize the surrounding gas and dust, forming intricate structures.

Just to make things clear, the Andromeda galaxy is visible all year from the northern hemisphere. Always.

🧵(2/2) As always, here she is with no stars and a zoomed-in version of the galaxy to enjoy the sheer beauty of the object. Remember that the light captured that evening took 2.5 millions years to get to us.

Starless version of The Andromeda Galaxy (M31). It is the closest major spiral galaxy to our Milky Way, located about 2.5 million light-years away in the constellation Andromeda. It is visible to the naked eye as a faint, fuzzy spot and contains roughly a trillion stars. Astronomers study Andromeda to better understand the evolution of spiral galaxies, including our own Milky Way, and it is a crucial target for research into dark matter.
