Observing and Sketches from December 19th through December 21st, 2017.


I got some observing in on December 18th and 19th, 2017 out at my dark site off of Forest Road 006 at Juniper Grove.  A couple of images. 



A little snow on the ground but the ground was dry and not wet on this trip out. Some clouds at firt over the Sheeprock Mountains that went away as night came on. A few bones on the site from a deceased animal. Only a couple and I moved them out and away from where I observe. 




The 17.5" Dob "Star Catcher" ready to go. The clouds are gone. 

Observations occurred on December 19th through December 21st, 2017. Location is Forest Road 006 Juniper Grove.  Time is from 17:30 to 04:00 on those days.  Conditions were Antoniadi II, with temperatures ranging from a low of 3 degrees F to an more warmer average of between 16 degrees F to 19 degrees F.  Instrument was my 17.5" dob, Star Catcher. 

I am making the sketches larger, they will go off the right side of the posting area so you can view them easier. We'll see how I like this set up. Off to work! 


1. NGC 266 Face on Spiral Galaxy in Pisces. 22mm T4 Nagler, 7mm & 5mm Pentax XW, Paracorr Type II.  NGC 266 is a bright, moderately size face on spiral galaxy that has a bright inner core, with a brighter bar seen.  I captured hints of the spiral structure coming off the eastern arm, with a hint of another arm coming off the western arm.  I have probably over emphasized the arms in the sketch but they were faintly observed. 


2. NGC 274 and NGC 275 or ARP 140, galaxies in Cetus.  22mm T4 Nagler, 7mm Pentax XW, Paracorr Type II. NGC 274 is the brighter of the two galaxies and it is the upper top one in the sketch.  NGC 274 in contrast to NGC 275 is round, has a bright inner core and well defined edges. 
NGC 275 is more oval, more diffused and larger and elongated SE-NW.  Bright core wit a blending of brightness, maybe a hint of an arm unconfirmed. 


3. NGC 392, NGC 394, NGC 397 Galaxies in Pisces, 22mm T4 Nagler, 7mm Pentax XW, Paracorr Type II. NGC 394 is the top small, faint galaxy; NGC 392 is the large central galaxy, NGC 397 is the faint galaxy down and to the left of NGC 397. 
NGC 392 is the brightest of these three galaxies though that isn't saying much.  It is elongated SW-NE, with edges that are diffused and is grainy in its texture.  
NGC 394 is very faint, and a condense round patch of light. 
NGC 397 is roundish, decently bright and well defined. 


4. NGC 410 & NGC 407 galaxies in Pisces.  22mm T4 Nagler, 7mm & 5mm Pentax XW with Type II Paracorr. 
NGC 410 is a relatively medium size galaxy that is rather bright.  NGC 407 is next to 3 stars and is a smudge. 





5. NGC 07, NGC 508, IC 1687, NGC 504 with 22mm T4 Nagler, 7mm Pentax XW, Paracorr Type II 
NGC 507 shows an outer envelope and an inner envelope and is brighter toward the center though the center's brightness is smaller in size.  This is the largest galaxy in the field. 
NGC 508 is a faint, round galaxy with an inner core appearing as a condense area of light at the center. 
IC 1687 is very faint, averted vision required to view it.  
NGC 504 is elongated SW-NE no structure evident and is a patch of light. 


6. NGC 660 Galaxy in Pisces; 22mm T4 Nagler with 5mm & 7mm Pentax XW, Paracorr Type II. 
NGC 660 is a large and beautiful galaxy being oriented SW-NE.  It has a very bright bar elongated SW-NE.  The NE portion of the bar is very bright with a high surface brightness.  The galaxy brightness diminished and becomes fainter and wider in the SW part of the bar and is fanning out from there.  Central region is very mottled and dusty.  The X looked more like a Y to me on the bar. Second faint arm on the NE and bends in the west giving the galaxy a warped S shape. 



7. NGC 827 Galaxy in Cetus: 22mm T4 Nagler, 7mm Pentax XW, Paracorr Type II 
Elongated almost perfectly laying east to west with tapered edges, and a diffused, opaque outer envelope.  There is some brightening near the core. 


8. NGC 894 a Galaxy in Cetus: 22mm T4 Nagler, 5mm & 7mm Pentax XW, Paracorr Type II
NGC 864 is a really interesting galaxy visually, especially at high magnification.  A magnitude 10 star is imposed/embedded on the galaxy ESE of the core, almost overcoming the galaxy's bright core.  The envelope is is diffused, round to oval in shape, more oval to me, elongated NE-SW to E-W.  The inner core has a bar and the core appears round.  Averted vision brings hints of structure in terms of arms. 



9.  NGC 908 a galaxy in Cetus.  22mm T4 Nagler, 5mm & 7mm Pentax XW, Paracorr Type II. 
NGC 908 has a very grainy outer envelope at high magnification, 600x-800x.  It is very large, very bright with well defined edges, and is elongated ENE-WSW. Spiral arms are easily viewed and in evidence. 


10 NGC 1044 & NGC 1046 Galaxies in Cetus.  22mm T4 Nager, 7mm Pentax XW, Paracorr Type II. 
NGC 1044 is the top and larger galaxy in the sketch. It is more roundish in shape to me than oval. Really, it is just a patch of fuzz in the eyepiece. 
NGC 1046 is smaller, fainter and more round. Another faint fuzzy patch of light. 



11. NGC 1070 Elliptical Galaxy in Cetus. 22mm T4 Nagler, 7mm Pentax XW, Paracorr Type II. 
NGC 1070 is a larger galaxy with a diffused outer envelope and a brighter interior.  Poor star field around it. 


12. NGC 1084 Spiral Galaxy in Eridanus; 22mm T4 Nagler, 5mm & 7mm Pentax XW, Paracorr Type II; 
NGC 1084 is well defined at the edges, opaque with brighter mottling over much of the disc of the galaxy.  It is both bright and large.  Structure is evident, arms are defined at high magnification and with averted vision. Great view! 


13. NGC 1153 Galaxy in Cetus; 22mm T4 Nagler, 7mm Pentax XW, Paracorr Type II. 
NGC 1153 has a diffused outer envelope with a sharp, round core that is almost, not quite, but almost stellar.  Round to oval in shape, more oval to me (seem more are more oval to me on this observing trip). 


14. NGC 1232 Spiral Face On Galaxy in Eridanus; 22mm T4 Nagler, 5mm & 7mm Pentax XW, 4mm University Orth; Paracorr Type II. 
NGC 1232 is moderately large face on spiral galaxy (a grand spiral) and moderately bright.  The galaxy brightens to a central core region visually and that core is well in evidence.  Bar possibly observed here and hinted at in the sketch.  Spiral structure is easily seen and sketched here.  Wonderful at high magnification in a large dob. 


15. NGC 1395 Elliptical Galaaxy in Eridanus. 22mm T$ Nagler, 5mm & 7mm Pentax XW, Paracorr Type II. 
NGC 1395 is an elliptical galaxy with an outer envelope that is faint, and a bright and somewhat large inner core region. 



16. NGC 1407 & NGC 1400 Elliptical Galaxies in Eridanus; 22mm T4 Nagler, 12mm TeleVue Delos, 7mm Pentax XW; Paracorr Type II; 
NGC 1407 is the largest galaxy in this view, it is round, opaque patch of light with a large round, non-stellar core. 
NGC 1402 is WNW of NGC 1407 and is viewed as a faint fuzzy, almost stellar, patch of light. 
NGC 1400 is smaller than NGC 1407, down and to the right in the sketch, and is viewed as being brighter than NGC 1407 which is due to its smaller and more compact concentration.  The galaxy is opaque with a bright even surface brightness in its outer envelope. 




17. NGC 1600 Elliptical Galaxy in Eridanus; NGC 1601 & NGC 1603 galaxies in Eridanus. 22mm T4 Nagler, 12mm Televue Delos, 7mm Pentax XW, Paracorr Type II.  
NGC 11600 is a bright galaxy and is elliptical with a bright inner core region.  NGC 1603 & 1602 are smudges of brighter light, easy to see in the field. 


18. NGC 1624 or Collinder 53, Open Cluster in an Emission Nebula in Perseus. 22mm T4 Nagler, 10mm & 7mm Pentax XW, 12mm Televue Delos; Paracorr Type II. 
Bright and large emission nebula surrounding five main stars with smaller ones evident in the open cluster.  NGC 1624.2 is the largest star in the open cluster and is responsible and the source for the ionization that is lighting up the emission nebula. NGC 1624.2 is the most magnetic massive star known, 35 solar masses and 20,000 times our Sun's magnetic field.  The open cluster is very young estimated at less than 4 million years old.  The emission nebula is easily seen and detail is evident. Looking carefully you can see how the emission nebula fades into the intergalactic background. This is one where the sketch in person is far better than the image captures as you can see more detail and faint detail in it. 



19. NGC 1637, Face on Spiral Galaxy in Eridanus; 22mm T4 Nagler, 7mm Pentax XW, 12mm Delos, Type II Paracorr; 
This is a very large and very bright spiral galaxy. The 22mm T4 Nagler easily detected the galaxy in its field of view.  The edges and extremities fade into the sky background nicely.  It is elongated NNE-SSW, the high magnification used shows a mottled core with bright extensions, Arms are evident.  



20. NGC 1700 Large Elliptical Galaxy & NGC 1699 Spiral Galaxy in Eridanus; 22mm T4 Nagler, 10mm & 7mm Pentax XW; Paracorr Type II.
NGC 1699 is on the upper top middle of the sketch and is a concentrated focus of light, a faint fuzzy with no structure except a well defined edge. 
NGC 1700 lays NNE to SSW while the core lays E-W. It is a young Elliptical Galaxy, possible from a merger from a smaller elliptical galaxy and a spiral galaxy and images from Chandra show a rotating disc of hot gases.  The outer elliptical is bright, the inner core brighter and almost stellar in lower magnifications. 


21. NGC 1961 or ARP 184 Spiral Galaxy in Camelopardalis. 22mm T4 Nagler, 7mm Pentax XW, Type II Paracorr. 
NGC 1961 is a distrubed spiral that is large, oval in shape and lays East to West. It has a very bright oval core that is offset to the northern part of the galaxy.  Large arm is visible sweeping East to West, on the south side of the galaxy.  Broad dust lane runs parallel on the inside of this arm.  Small arms possible north to west, running west to south.  Nice view. Again, here the original sketch is better than the photograph image above as the actual sketch has more subtle features and brighter and fainter parts stick out more. Still learning the camera I am using but the image is better that what I use to post. 



22. NGC 1609, NGC 1611, NGC 1612, NGC 1613 Galaxies in Eridanus; 22mm T4 Nagler, 14mm Pentax XW, 10mm Pentax XW, 12mm TeleVue Delos, Paracorr Type II. 
NGC 1609 is a very small and faint galaxy that has a small condense and bright core, good stellar nucleus can be seen. 
NGC 1611 is a small, faint elongated WNW-ESE with a large bright core. 
NGC 1612 is a very faint, small, round shape galaxy that has a faint stellar nucleus and is the faintest galaxy in the group and in the sketch. 
NGC 1613 is small, faint, partially elongated SE-NW.  Bright core with a stellar nucleus. 



21. NGC 496, NGC 195, NGC 499, NGC 498 Galaxies in Pisces; 22mm T4 Nagler, 10mm & 7mm Pentax XW; Paracorr Type II.
NGC 498 is a very small, extremely faint fuzzy galaxy with no details.
NGC 496 is a faint, oval shape patch of light, elongated NE-SW.
NGC 495 is the western part of this triangle of galaxies and has a bright inner core region though it is a small galaxy.
NGC 499 is the largest of the 3 galaxies, is a barred spiral but we cannot see the bar or arms visually, we cannot see any structure,  and it is elongated just off the W-E line. Oval in shape.
