Abell 35 - a not-so-planetary nebula

Image Description and Details :

We are glad to propose you this beautiful picture of Abell 35 . It was taken with a Planewave CDK12.5 and a QHY600 M camera in Chile during several nights of january and february 2021. The resulting image is a mix of RGB band images for the stars and HO images for the nebula itself.As you are probably aware, Abell 35 still remains considered as PN on SIMBAD but Jacoby had already raised questions about its true nature as early as 1981. Recent studies (after Frew and Parker, PASA, 27, 129, 2010) conclude that the nebula is a Stromgren sphere in the ambient ISM, ionized by a hot DAO white dwarf companion of BD – 22º 3467 which has recently evolved from the PN phase. The system produces a strong wind, probably from the fast, rotating subgiant which interacts with the inner zone of the emission nebula to produce a dramatic parabolic bow-shock aournd BD – 22º 3467 that is strongly visible in the OIII narrowband datas.

Battle of the Moons

Image Description and Details :

The image displays the angular size difference between a "super" moon and a "micro" moon. The micro moon is the Cold Moon of 2020 (captured on 30th December 2020) and the super moon is the Pink Moon of 2021 (captured on 27th April 2021). The super moon gets almost 10% bigger in the night sky due to its closer approach to Earth.Gear: Nikon D5600, Sigma 150-600cPost-processing: PIPP, Autostakkert, Adobe Camera Raw, PhotoshopCapture Date: 30th December 2020 and 27th April 2021Location: Kolkata, India

Notes

NGC 3642 is a spiral galaxy with an active galaxy core in constellation Ursa Major, about 75 Million light years away from our Milky Way. The galaxie belongs to the NGC 3642 group (also known as NGC 3610 group), a galaxy group that also includes the elliptical galaxies NGC 3610 and the lenticular galaxy NGC 3619.
The elliptical galaxy NGC 3613 and the barred spiral galaxy NGC 3625 are part of the NGC 3613 galaxy group. These two galaxy groups are considered associated.

Some of the galaxies, especially NGC 3619, seem to have one ore more tidal streams.

M82- The Cigar Galaxy

Image Description:

M82 is also known as the Cigar Galaxy for its elongated visual appearance, it is a starburst galaxy with a superwind. In fact, through ensuing supernova explosions and powerful winds from massive stars, the burst of star formation in M82 is driving the prodigous outflow of material. The filaments extend for over 10,000 light-years. Some of the gas in the superwind, enriched in heavy elements forged in the massive stars, will eventually escape into intergalactic space. Triggered by a close encounter with nearby large galaxy M81, the furious burst of star formation in M82 should last about 100 million years or so. M82 is 12 million light-years distant, near the northern boundary of Ursa Major.
