NGC4244 on the lower left and NGC4214 middle right.
It’s NGC4214 that piqued my interest. The most obvious is how chaotic it looks. On further investigation it’s classed as an ‘Irregular’. In my copy of ‘Hubble Atlas of Galaxies’ it goes further and names them as Irr Type 1 or Megallanic Cloud type irregulars. If they took the Large Megallanic Cloud and repositioned it 11 mly away it would look very much like NGC4214 shown here.
It’s also called a s Starburst galaxy, which is one with an exceptionally high rate of star formation compared to the average. This activity is so great, that around the 6 or so blue star clusters, the stellar winds form bubbles in the surrounding gas. Over time these bubble increase in size as the Hot ‘O’ type stars within them grow older. This activity is so great that these galaxies are often called Wolf-Reyet galaxies. As well as containing lots of new young stars, this galaxy contains many old red supergiants which suggest that this bout of current star formation is not the first and with the abundant supply of hydrogen will likely continue to do so in the future.

M16 & M17 by Dr Nigel Price
This is the Eagle Nebula (M16) centre and the Omega Nebula (M17) bottom right. Both are quite low to the horizon….lots of stars due to the proximity to the galactic bulge…over 230,000 point sources in the image!

NGC6205 – M13
M 13 imaged on 20th April 2024. It was on my list for a while so I decided a one night window on the weather would suit this target. Integrated in PixInsight WBPP2 with 2X drizzle. Saturation adjustments were carried out in Photoshop Camera Raw Filter as a 16 bit TIF before saving the JPEG. By Barry Trudgian
