Makemake, April 30, 2020, from 5:33 to 8:01 UTC


This image was taken on April 30, 2020, from 5:33 to 8:01 UTC.  Makemake is the short streak just above the center of the frame, next to a bluish star.  Here is a cut-out with the well-known space-arrow nebula pointing at the dwarf planet:

The image is 13x600" exposures, with 4 dropped frames within the named time frame. Camera: Atik 460EXC, Astronomik CLS filter. Telescope: 203mm Synta-ONTC Newtonian at f/4.95, Baader MPCC.

At the time, Makemake was 431.23 light minutes from eath.  It's light took 7 hours 11 minutes to reach earth.

Down is west in this image. The planet's movement was from up to down in this frame, the dwarf planet appearing to head west, in retrograde.

The dim star to the right and a little above where Makemake started is mag 18.65.

The bright galaxy at 1:30 o'clock from Makemake is PGC 140072, 1 billion light years away.

The galaxy just to its right at 4:30 is mag 18.35 PGC 1699049, 2.8 billion light years away.  It's companion just to the right is PGC 3802286 at 2.7 billion light years, mag 18.99.  I did not find information for the galaxy below them that forms with them an equilateral triangle.

The bright star to the left of Makemake is mag 12.41.

To the left and down at 7 o'clock from there is a mag 17 star, and just left of it another galaxy, PGC 1697253, mag 18.16, 1.8 billion light years.

Other than that, the spot of fuzz in the upper right quadrant of the large image is PGC 1702155, mag 17.2, 1 billion light years away.

The brightest star in the image is SAO 82643, mag 9.21, 289 light years away, type KO.

Below that is SAO 82639, mag 9.73, 960 light years distant, type G2.

And the bright star to the bottom right is TYC 1993-1675-1, mag 9.8.

Here is a screen shot from SkySafari.  (The dim galaxies show up only at a more minute scale.)

And here is a black & white inverted version:

Nice deep image Val
I'm pretty sure I see dozens more faint background galaxies above (West) and upper left in the image. Interesting to see what magnitude & distance they are at.

Regards,
Bill

Yes, they are there. I just ran out of steam naming them. Plus, I've been working on an image of Abell 2199 in Hercules. I probably have 200 galaxies in a single image. That's probaby up next.
