Widefield Milkyway Mosaic - Starless Edition by Deepanshu Arora, on Flickr

This was done using Canon EOS Ra and Sigma 40mm f/1.4 Art lens. 4 panels data was collected and stitched to get even wider FoV. Starless version was primarily created to help boost the faint nebulosity in the final image, but I ended up liking the starless version lot more than one with stars. Many of the emission nebulas can be seen clearly with their precise shapes, for example Cat's Paw.

Welcome to Starship Asterisk*, deepanshu29! That's a very nice first post of yours!

This beautiful lenticular galaxy in southern Virgo, is one of largest and most massive galaxies in the Virgo Super cluster of galaxies. We view it almost perfectly edge on, so while it appears only about one arc min in thickness, in this very deep image, NGC 5084 spans almost 17 arc min of the sky, which, at an estimated distance of 80 Million light years, means it is nearly 400,000 light years in diameter, which in anyone's book, is one seeeriously gigantic galaxy!

Supernova SN 2020jfo in a weakly-barred spiral galaxy NGC 4303 (M61)

Copyright: Velimir Popov, Emil Ivanov

The supernova SN 2020jfo was discovered by The Zwicky Transient Facility (ZTF; Bellm et al. 2019; Graham et al. 2019) in a weakly-barred spiral galaxy NGC 4303 (M61) on 6-th of May 2020. ZTF reported a rapidly rising young supernova in the nearby galaxy M61. Assuming the redshift of the host (M61, z=0.005224 from NED), and the distance of ~19 Mpc the SN was discovered around absolute ZTF r-band magnitude of Mr = -15.8. The follow up rapid spectroscopy reveals a blue continuum that suggests a core-collapse supernova origin and was classified as a young Type II supernova. Total amount of eight supernovae was discovered in NGC 4303 since the first one in 1926 followed by SN in 1961, 1964, 1999, 2006, 2008, 2014 and 2020.

Dusk & dawn with C/2020 F8 (SWAN) comet

A composition made of 52 north latitude when there was no astronomical night. Sun was just 17 degrees below the northern horizon.This allowed to show two phenomena: the passage between day and night and the northern part of the sky with the SWAN comet. The composition was made up of 84 vertical shots. The total exposure time is 84 minutes. Canon 6D, Samyang 135mm f2.

With lots of luminance acquired during my Sombrero Galaxy (Deep) project looking for tidal streams...

https://www.astrobin.com/ifvnh6/B/

... I thought I'd spend another night acquiring RGB to produce this "Deep with color" version.

With 30 minute subs, the core is saturated. Given that, HDR processing to expose the core is minimized.

I primarily focused on stretching the surrounding space for a more "big picture" view of this wonderful galaxy.

SH2-27 an area that is not imaged very often probably because of the Rho Ophiuchi nearby.

This image was taken at my cottage and it is 230x60s using Canon 6D, Samyang 135mm @f2.4 and ISO800

M61, NGC 4292 and NGC 4301
http://www.emilivanov.com/CCD%20Images/M61_LRGB.htm
Copyright: Emil Ivanov

Emil Ivanov's image shows the striking brightness of M61 compared with the faintness of its satellite galaxies, NGC 4292 (upper right) and NGC 4301 (upper left).

NGC 4301 is an interesting galaxy that has rarely been photographed. There exists an SDSS photo of it that shows the galaxy to be a relatively low-mass dwarf with a rather faint yellow bulge and a somewhat rudimentary spiral structure. The galaxy hosts up to ten bright knots of star formation.

NGC 4292 contains no star formation at all, but it does display some ring or shell structures in this image by Alson Wong. Also check out the brilliance of the regions of star formation in NGC 4301 in Alson Wong's image.

Hello,

I hope you guys are fine with this covid nightmare.

This is my latest shot of Carina nebula NGC 3372 from my rooftop in Lima, Perú.

High resolution version here:
https://www.astrobin.com/full/d0oayr/B/

I used a Celestron EDGE 8 HD at 2032 mm f10, which allowed me to capture 4.2 hours of exposure time (126 / two minute shots). I used a Celestron CGEM mount, and a ZWO ASI 071 color camera.
Guiding a 2032 mm isn`t an easy task so I used a Celestron OAG coupled with a ZWO ASI 174 MC guiding camera. As I am shooting this target in the middle of a bortle 9 city, I used a light pollution filter (IDAS LPS-D1) to minimize light pollution problems.

I also got the Homunculus nebula, which requiered lower exposure times. I did 74 (five second shots / gain 0), and another set of 40 (thirty second shots / unity gain) for the outer layers of the homunculus nebula.

I finally merged all exposures in one single image.

Hope you like it!

Cheers from Lima, Perú

Several folks requested I update my prior FOV to possibly capture more tidal streams. 21.5+ SQM overhead skies, but closer to 21.2 SQM where I was pointing.
