Virgo Part II: Observations

Here is Part 2, the observations.... enjoy!

M49 A round glow with a bright core. A nice one similar to M87 50X.

M53 A globular cluster NOT a galaxy. It is somewhat resolved and takes power up to 109X pretty well. A nice break from those dim galaxies!

M58 A bright core, mostly evenly bright oval. 50X

M59 A bright oval that brightens more to the core. 50X

M60 It is a brighter galaxy with NGC 4647 nearby. It Averted Vision the galaxies look to touch? 50X

M61 A round glow, with a core, the round halo part of the galaxy is not really even in brightness. 50X

M64 A bright round glow. Even with averted vision not really seeing the black eye, maybe a hint of it. Kinda in a no mans land for star hopping. 50X

M84 A little brighter then M86. A bright oval with a core. 50X

M85 A bright core with a fainter halo. NGC 4394 pairs up with this galaxy.50X

M86 A little fainter then M84. It appears maybe a little bit bigger and/or extended then M84. 50X

M87 A round glow that is bright core. It has a jet, that can be seen with larger scopes 50X.

M88 A bright core, the rest is a oval glow that is somewhat pointed to the south east. Maybe a field star(s) is imposed on the galaxy in the south eastern side.

M89 A bright and round glow. 50X

M90 A unevenly bright and round glow. It has a nice core. 50X

M91 A small but bright core, the rest is just a circular glow. 50X

M98 Pretty bright, elongated but not even in brightness. The core is not every even in brightness either. 50X

M99 Elongated, with a core. Not really seeing the spiral structure with Direct or Averted vision. 50X

M100 Very bright and has a nice core that is round and small. The edges are kind of diffuse. 50X

M104 The Sombrero!, I can see two lanes pretty easily, but it really doesn’t look like a hat though. Very nice. Bright. 50X

I have included all the objects one would hunt down while doing the Virgo/Coma galaxy hunt. I also included M53 which if you are hunting these galaxies down is a nice distraction from the “dim oval” or “dim smudge” of the galaxies. I have always found galaxies interesting but with the rural skies of where I live and the size of scopes that I owned, galaxies have never really been a favorite. They really do take patience and good skies to be able to tease the details out of.

My notes I kept short for the blog and also pretty general. Hopefully they reflect pretty well the impressions that others would have under similar conditions with similar equipment.

I think star hopping these galaxies is really something everyone should do at least once. It really teaches you how to use your scope and navigate the sky in area that is pretty tough to star hop. Once you get started though one mostly just galaxy hops in this area.

Virgo Part 1: My equipment & resources for observing Virgo Messier List Galaxies

This past month I was able to get in a epic observing run to catch all the Virgo galaxies and I was victorious. I did it by star hopping which was a little tough being there isn't a lot of stars to hop from in Virgo. I found a few things essential in getting successful results:

1. A 8X50 Right Angle Correct Image finder scope.
2. Knowing how big the FOV of my finding eyepiece with my scope is (50X with a 1.3 degree field of view)
3. A book with the images of the galaxies. I used The Messier Object by O'Meara.
4. Sky Safari 3 on my Macbook.
(I also used the recent binocular observing article in Sky Telescope from April 2016)

Now do you need all 5 of these things, well no. I do think the first three are pretty valuable. An observer could get by without the Sky Safari and the magazine article if they had a good star chart. Actually there are probably some better printed materials out there for the Virgo cluster then what I used.

I found the galaxies in Virgo to be pretty tough, mostly because of the lack of stars to hop from AND well with an 8in scope galaxies are not going to be bright unfortunately. The skies at Chandler Mountain are darker then where I live, but they are not super dark either. The Milky Way is pretty easy to see in the summer but it is a bit harder in the winter. I also found hopping the Virgo area to be mentally taxing somewhat too. One is pointing their scope in a somewhat small area of the sky, but there is numerous galaxies in the area, so one has to galaxy hop a lot. Also knowing how big your FOV is helps, because for me I can count FOVs to move around in a tougher area of the sky. I personally set my Sky Safari to show the rings for a Telrad and the FOV of my 8X50 finder. I found myself taking my time, studying the image on the laptop and comparing it to the book a lot. I would highly recommend reviewing or looking at sketches of these objects before going out and observing. Try and find sketches made by folks using a size scope similar to your own. I like using The Belt of Venus blog
, but there are others out there too.

I used mostly my 24mm eyepiece which gives 50X with my scope. I find that eyepiece and my 11mm eyepiece are my two favorites for deep sky objects. I also use a 16mm some too if the 11mm is too much power or I just do not like the view. All my eyepieces except one are from Explore Scientific or Meade and are either 68 degree or 82 degree. The three eyepieces give 50X, 75X and 109X in my scope. I also have a oldie but a goodie Orion 32mm Optiluxe, which is for really low power and comets! For higher power observing I have 8.8, 6.7, 5.5 and 4.7 eyepieces from the Meade 5000 series line. I use them for the Moon and planets.

My telescope is a 8in f/6 Orion Skyquest XT dob. I have the 8X50 Orion RACI finder and a Telrad. I use the ScopeStuff magnet weights to balance the scope with the two finders up front putting so much weigh on the scope.

Thanks for reading! Next month will be Part 2, which will be my observations and thoughts on the galaxies. Till then Clear Skies!
