NGC4631 (w/NGC4627) - The Whale in Canes Venatici LUM - edge on spiral.

Orientation: North is RIGHT  - Distance: ~25-30 million light years 

Image Size: ~27x20 arc minutes  - Image Scale: ~2.12

 

DATE: 06/17/2009

Conditions: Seeing Good . Transparency Good. Stable skies. Temp ~40-45 degrees F (very cold for June!).  Serious dewing problems on guidescope resulted in somewhat ovoid stars due to bad tracking.

 

This is a PRELIMIARY image. I plan to obtain more data, potentially reshooting this object in better conditions due to the guiding errors.  Eventually this will be an LRGB full color image as I obtain more data.

A beautiful, bright, and relatively close interacting spiral. An interesting smattering of background galaxies in the field with at least one discernable edge-on spiral. Plenty of structure, nebulosity, and dark lanes.  COLOR RGB data has been ADDED.

This is known as the Black Eye Galaxy, also the Sleeping Beauty Galaxy. I have no idea who coined that name or why. This is a galaxy with very smooth features and an interesting 'black eye'.  More signal would surely help here, but time was limited when I took this. I may return to this later.

A very interesting trio. Three galaxy types/perspectives very close to one another. You have a side view, a spiral, and a irregular in the middle. I brought the background up so you can see the background galaxies. I will label these later. There are at least 7 faint fuzzies in there, though I suspect there are a few more. This shot could use a lot more exposure to bring out some more detail and help smooth the image.

Note the 'filaments' above and below the galaxy core (at the poles). These are jets of hydrogen gas being blown away from the galactic core due prolific star formation.  It is believed that tidal interactions with it's partner galaxy (M81) are causing this.

Oh what a difference some practice makes!  Same data. First time I didn't know what I was doing. Second time... I better understand what I am doing.. what a difference.

Comment:

No Darks, Flats or Bias were used. No use of an autoguider! Turns out I need yet another USB to Serial adapter. Very minor MANUAL guiding adjustments were performed every 5 minutes during exposures mostly due to polar alignment being off slightly. Rather consistent, yet slow drift observed in southwesterly direction. I am very impressed with the Losmandy G-11. I suspect this image can be much better processed, but considering I am rather green at this, I think it came out quite well. There is a bit of noise in the image plus I think the spiral arms could be coaxed to come out a bit more.

NGC3628 - Edge On

*early test image*

 

Comment:

Mag 9.5. Edge-on spiral galaxy. Very close to M65 and M66. This isn't a very good shot, but not bad for my earliest of galaxy shots.  Goofy venetial blind effect visible in the stars. Noisy/grainy image due to need for longer exposure (not enough data). Still, you can easily make out the dust lane and the somewhat 'warped'  arms at each end of the galaxy. I'll be back.

Nice pair of galaxies. I like how they can both be easily framed within a single image. Low res. But this is just a start.

Comment:

Mag 8.9. I took this later in the night after M65. As you can see noise is greatly reduced due to much darker sky.  Seeing apparently improved greatly as well. Guiding had some issues, as you can see from the sighly non-circular stars. With more data, and processing effort, this could be quite a good image.
