The galaxy group Hickson 44 in Leo. This is based on 29 x 240 s, plus bias and flats.
Hickson 44 in Leo:
There are some other galaxies near by, some of which are names in this overlay from Astrometry.net:
Overlay from Astrometry, naming the other objects:
The main ones are NGC 3190, NGC 3185, NGC 3187 and NGC 3193. NGC 3190 has a well defined dust lane. NGC 3187 is a barred spiral galaxy with two arms. NGC 3193 is an elliptical galaxy.
The light captured by my camera last night left these galaxies just after the extinction event killed the dinosaurs on Earth.
From APOD: Galaxies, like stars, frequently form groups. A group of galaxies is a system containing more than two galaxies but less than the tens or hundreds typically found in a cluster of galaxies. A most notable example is the Local Group of Galaxies, which houses over 30 galaxies including our Milky Way, Andromeda, and the Magellanic Clouds. Pictured above is nearby compact group Hickson 44. This group is located about 60 million light-years away toward the constellation of Leo. Also known as the NGC 3190 Group, Hickson 44 contains several bright spiral galaxies and one bright elliptical galaxy on the upper right. The bright source on the upper left is a foreground star. Many galaxies in Hickson 44 and other compact groups are either slowly merging or gravitationally pulling each other apart.
This image is based on 19 x 300 s , plus flats and bias. It shows a LOT of galaxies, in a grouping called Abell 1367. In this image you are looking at part of one of the biggest structures in the Universe, the Great Wall.
The Leo Cluster (Abell 1367) is a galaxy cluster about 330 million light-years distant (z = 0.022) in the constellation Leo, with at least 70 major galaxies. The galaxy known as NGC 3842 is the brightest member of this cluster. Along with the Coma Cluster, it is one of the two major clusters comprising the Coma Supercluster, which in turn is part of the CfA2 Great Wall, which is hundreds of millions light years long and is one of the largest known structures in the universe.
The overlay from Astrometry gives some of the galaxies visible in the image.
The August galaxy of the month (the 100th one actually) from the Webb Society is NGC 7042 in Pegasus.
So I thought, better get that new 20 inch dob out and try it. The sky was a bit milky and there was a lot of high cloud around but that was not going to stop me!
Well I found NGC 7042 fairly easily. You can tell its a spiral as it has that characteristic low surface brightness glow across its entire face. It sits next to a triangle of stars. I then worked hard to see if I could see NGC 7043. I could not see it last time I tried when I had a 14 inch scope. Well this time I got it just! Very faint even with averted vision but definitely there. I managed to see stars to mag 14.9 despite the poor skies.
Here is my observation:
I also had a look at a few more galaxies on my target list, IC 1473 in Pegasus (within a triangle of stars) and IC1550 in Andromeda. That brings my total galaxies observed up to 1800.
Here is IC1550 from Aladin. Perhaps not galaxy of the month but it was special to me as no 1800 and it looks lovely next to that field star. I read that it is about 275 million light years away behind the Perseus-Pisces supercluster wall of galaxies.
Another great night of observing with the new 20 inch scope.
Do give any of the above targets a go as they are well placed to the east at the moment (which is best for me over the Cotswolds!) and let me know how you get on.
Thank you to Owen for the inspiration.
Hi guys, I'm new here.
So i have heard from this source:
that the galaxy andromeda will be visible to the naked eye and look bigger than the moon. They said that it will happen in August, but didn't specify a day.
Does anyone know anything about this? Or about how i kann see it?
Thanks in advance and sorry if my grammar is bad

For Deep-Sky AP of mostly galaxies (and nebulae), what'll give me the best results– a medium-weight 130 P-DS or a very lightweight wide-field WO Z61? I know the "best" telescope is one that doesn't just collect dust all day long, but I just can't figure it out. Supporting said telescope will be the SW HEQ5 PRO Synscan (with the Rowan Astronomy belt attached), which will be supported further by a autoguiding system, possibly a very lightweight CF 32mm refractor with a ZWO ASI 120mm Mini (Can't find the -S model in Japan). On the telescope'll be the Canon EOS 600D, quite a heavy beast IMO.
Instead of leaving it here, I'll say (just blurt out) everything I know about these seemingly-equal telescopes.
The 130 P-DS, clocking in at F/5, will produce fantastic photos of Nebulae and Galaxies alike, although its aperture will slightly limit the galaxies it'll see. It seems this telescope does particularly well when it comes to imaging M81 or M51, and Nebulae like the Rosette. Its price-performance ratio is basically unbeatable, as it's only 250$ over here in Japan and it cranks out fantastic images. The only addition I'll need will be a F/5 SW-issued Coma Corrector; however, I don't need to worry as I'll be getting one from me mum in a few week's time.
The William Optics Z61, which has a slightly higher F number of 5.9. It sports 2 lenses with FPL-53 elements in them, allowing for extremely high contrast images of nebulae like the Rosette, Orion, all that lot. I've previously asked a similar question, and I've been convinced by the answer that "I won't really be able to take images of galaxies other than M31, Andromeda, and M33, Triangulum. So why do I even have this as an option when I could just go with the cheaper 130 P-DS? Well because it's a wide field APO. Everything it supports, whether it be the design to the focuser, is just amazing, so much so I can't emphasise the emotion enough.
On Astrobin, I've checked out what kind of images these telescopes produce, and I encountered a problem– pretty much everyone was using everything but the 600D. They all used the fancy Mono-cooled CCDs like the ZWO ASI 1600MM Pro.
Hi, this is my first time using my new Esprit 100ED, my first time processing using Pixinsight, and it's my first image using a Mono + filters.
I loved them, can't wait to try on more targets.
here's the result:
SkyWatcher Esprit 100ED
SkyWatcher EvoGuide 50ED Guidescope
Imaging cam ZWO ASI1600MM Cool Pro
ZWO LRGB+NB 36mm filters
Guiding cam ZWO ASI290MM Mini
