Virgo group galazies: Siamese Twins and M58

Recommended Posts

Posted (edited)

Here is a bunch of Virgo cluster galaxies. The twin galaxies are in the process of colliding and merging with each other with the highest star-formation activity in the part where they overlap.

Collected with the Esprit 150 with ASI071 sitting on the Mesu200. On 30th March I managed to get 15 x 10 min, and 1st April gave me 45 x 5 min (I reduced the exposure time as the 10 min exposures blew out the core a bit of M58). Gain was set at 200 (offset 30, -15°C).

This is my last galaxy shot for a while. Now the moon is up and the moon and galaxies do not go well together, as I confirmed with an over-optimistic try last night🥴. Maybe I get a few more chances later in April but after that the sky will be too bright up here.

Wow--so different than Astrobin--it looks much closer in.  Very nice--like I am looking through a 23rd century telescope.  The palette is subtle, yet strong

Thanks Rodd! Yes, it is sometimes striking how different our images look at different platforms, and different screens. Glad you like it at SGL!

Take care

Lovely image, not seen that one before Goran.

Thanks Alan!

I try to find objects that are not among the most imaged and there are enough galaxies out there.

Same here. Except it's raining here as well:(

Thanks a lot Hunter! Here the sun is in full force and the thermometer reached 15 C for the first time this year, but the moon is of course out in full anti-AP force......

Yes, but there is a Goldilocks zone: unusual but large enough to show detail. 

Very nice image btw, Göran.

Yes, but in combination with clouds and moon consipring, I think there are enough of them out there for my Esprit 150 to be busy for a few years, and if it runs out of galaxies, I have 10 times more for my 3.5 m FL SCT.

      The galaxy M58 is located in the Virgo constellation and is approximately 65 million light years from Earth with a disk diameter of approx 110 thousand light years. 
      It's relatively low in new star formation, having little hydrogen gas which is concentrated in its elliptical core. The core is relatively dim and is believed to contain a  super-massive black hole of 70million solar masses.  Images of this object are rare on SGL, so I thought I would attempt to capture it. 
      The LRGB image below represents just over 10 hours integration time and was taken with my Esprit 150. If you look closely,  you can see a few details of the core.

      I and Wim are doing our best to fill up this forum with what we find to process on the Liverpool Telescope site. But what else could we do up here in Sweden where the night is twilight for several months?
      Here is today's contribution from me: Two colliding galaxies. Even if this is only 20 subs and 30 min (!) of data I think it stands its ground with the help of 2 m of aperture.
      Subs used and filters:
      5 x 90 s of sdss-r (red channel)
      5 x 90 s of Bessell V (green channel)
      10 x 90 s of Bessell B + sdss-g (blue channel)

      NGC 4567 and NGC 4568 (nicknamed the Siamese Twins or the Butterfly Galaxies) are a set of spiral galaxies about 60 million light-years away in Virgo. They were both discovered by William Herschel in 1784. They are in the process of colliding and merging with each other.
      Taken with reasonable guiding but poor seeing conditions using a Skywatcher clear sky filter. For more details the astrobin link is: http://www.astrobin.com/248908/
