Leo`s mane

Recommended Posts

Had alot of fun observing galaxies last night, despite poor transparency.

Picking up dozens of galaxies in Virgo, Leo triplets, and M51, M63, M94.

 

I did however fail to detect the Galaxy cluster in Leos mane. (ngc 3185, 3189, 3193 etc)

I`ve observed them before (3 of them), but I cant remember the eyepiece focal length used.

Can you recommend the best optimal Power / exit pupil for these faint Objects?

I use 8"dob F6.

 

Regards

20mm should see you right!

They are big enough not to need the higher mags. Getting more than three in an 8" is very good going under anything less that pristine sky.

20mm was the (only) one I used. Must have been the poor transparency/ my own impatience that made it difficult to spot these galaxies last night.

At F6 you could try a 24mm. But transparency of the sky is more likely to be the issue.

I use NGC2235/2236 Arp94 as my indicator targets for that area. If I can see them, then the chances are good for other faint stuff.

      There is something that makes me think practicality.  
      We can all agree that a long focal length scope is better suited for planetary use than its short length brother which would be best suited for dso viewing or guiding/photo. 
      We can take those two (refractors) as an example: 90/900 and his brother, a 90/500 (and we will be using Plossl EPs)
      Exit pupil is an important factor in viewing comfort. 
      Exit pupils are dependent on the scope's focal length, the EP's fl and the main lens diameter.  
      For example, to acheive 100x in the 90/500 we will need a 5mm eyepiece and to acheive the same mag in the 90/900 we will need a 9mm eyepiece. 
      The exit pupils of both scopes in those configurations will be 90/100=0.9mm 
      The theoretical magnification limit for both scopes lies at about 180x. 
      It is true that to reach this 180x you will need a 5mm EP in the 90/900 and a "2.8"mm EP in the 90/500 and those will probably make for an eyelash brushing eye relief... But looking at exit pupils up to 100x, those scopes do not seem to complement one another, but rather replace each other.
      So, ignoring abberations, and not taking into account eye relief so much, wouldn't the faster scope be almost as practical and easy on the eyes for high-ish magnifications as the slower, heavier, harder to mount in the wind scope?
      just my evening neurons buzzing...

      Equipment Used:
      Scope: 20” f3.6 Lukehurst Dob with Paracorr (fl = 2089mm & f4.1).
      Night Vision: PVS-14 with Photonis 4g INTENS.
      Eyepiece: Plossl 55mm (f2 x38).
       
      Background.
      In spring 2019 I created a Sky Safari observing list of 214 highest brightness galaxies in the night sky above.
      I have observed 134 of the 214 (the others have not been well placed over my garden when I have been outside).
      In my first pass through these 134 galaxies, they were graded 0-3 (where 3 means "clear spiral arms" and 0 means "nothing to see here!")
      I have now completed a second pass through the grade 2 and grade 3 galaxies. This has resulted in some movement between bands based on my now greater experience and having a better idea of what I expect to see.
      My latest graded lists contain 38 grade 3 galaxies and 30 grade 2 galaxies (when combined this gives a list of the best galaxies to view when using military night vision technology combined with a low power eyepiece (using the TeleVue PVS-14 adapter).
      [Note that lower power eyepieces give the best spiral arm results as they “increase the effective focal ratio” of the telescope/night vision system which really helps increase the detail seen at the eyepiece.]
      As we are still in galaxy season 2020, now seemed a good time to re-publish my findings so others have the opportunity to observe some of these fantastic galaxies before they become “unavailable” for another 10 months…
       
      Grade 3 galaxies (the best of the best).
      M51 M61 M64 M65 M66 M81 M90 M91 M94 M95 M96 M99 M100 M101 M106 M109 NGC891 NGC2403 NGC2903 NGC3184 NGC3628 NGC3631 NGC3726 NGC3893 NGC3953 NGC4051 NGC4216 NGC4274 NGC4449 NGC4559 NGC4565 NGC4618 NGC4725 NGC5248 NGC5371 NGC5746 NGC5907 NGC6946  
      Grade 2 galaxies (good but the arms are not quite there…)
      M82 M88 M98 M104 NGC2537 NGC2768 NGC3294 NGC3344 NGC3373 NGC3596 NGC3646 NGC3675 NGC3718 NGC3729 NGC3813 NGC3938 NGC4013 NGC4214 NGC4293 NGC4389 NGC4490 NGC4517 NGC4535 NGC4625 NGC4762 NGC5005 NGC5364 NGC5383 NGC5775 NGC6015 Hopefully someone will find this useful information, next time they plan a galaxy observing session...
      Note that my dobsonian uses an Astrodevices Nexus unit which I control using Sky Safari. Here are my exported observing lists (which you can import into your Sky Safari app should you wish to do so?)
      Grade 3 Galaxies.skylist
      Grade 2 Galaxies.skylist
      1. email them to your phone/ipad,
      2. read the email on your mobile device and after clicking on the attachment, you should be offered the chance to “send to Sky Safari” by your email app…
      3.Sky Safari will open and give a message “Observing List Created”.
       
      Clear Skies,

      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.
       
       
      Abell 1367
      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.

      Wikipedia:
      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.

      Hi, i..m on Stargazers Lounge for long time ago, but now i have a new scope at last!!! The scope is a Skywatcher classic200p dobsonian, and i received it just one month ago. I.m really happy with it. For now, i.m using the stock eyepieces that come with the scope, a 25mm and 10mm super plossl 52. Yesterday i was received a Celestron Omni barlow, and that expands my magnification range. I posted some pics with my set. 
      Congratulations to Stargazers lounge team, this is one of the best sites to learn about astronomy and equipment. 
      Besf regards to everybody

      lets imagine I wasn't to see a nice DSO about 15' size and I think it should look good nicely framed with a 1 deg field of view in the EP..
      Which would give the better (or higher probability of seeing anything at all ) view from a semi urban light polluted home site (e.g Bortle 6)?
      a) an 100mm f/6 refractor (fl 600mm) and a 10mm EP (60 deg afov, gain 60x = fov pf 1 deg)
      (and exit pupil of 100mm / 60 = 1.6mm)
      or
      b) a  200mm SCT with focal reducer to give f/6 (fl 1200mm) and a 20mm EP (60 deg afov, gain 60x = fov of 1 deg)
      (and exit pupil of 200 / 60 = 3.3mm)
      My gut feeling is that the SCT should give a better view just based upon its 2xaperture - but Im not sure I understand fully the maths why.
      Is the larger exit pupil going to result in a better / brighter / more successful view?
      Or will the view be 'roughly' the same ?
      Or have I got it all wrong.....

      Thanks.
