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!
