Observing, Monday, September 26th, Tuesday, September 27th and Wednesday, September 28th, 2016 FR006 Juniper Grove








Last week I was able to get out and enjoy several key nights of just wonderful observing. I did something different and will be adding them here. I took photo's of the site so you can see the location, but more importantly, I took video of the location. The video I took has me commenting and one of me just walking around and filming the site.

Here they are: 




This is the silent video that only captures me walking, but really the quiet of the site in early evening. 





This is the video of the observing site with my narration (ignore unless you want to hear me). Here are the pictures from this observing run. The last two are of my friend Alan's refractor he brought to observe. Wonderful instrument! 















Again, I am not going to re-order these as I observed and sketched them. Look at the time if you want that info. 




1. Abell 75 or NGC 7076 a Planetary Nebula in Cepheus: Mag. 13.2; Central Star 17.4; Size 1.1'; September 27th 2016; 11:20pm MDT; FR006 Juniper Grove; Antoniadi I, steady and cool; SQM: 21.69 Milky Way Overhead; 17.5" Dob Star Catcher; 22mm Nagler T4; 10mm, 7mm & 5mm  Pentax XW; Paracorr Type II; Thousand Oaks OIII Filter. 

Same sketch above, the top one is just taken zoomed in closer to the sketch, the second or bottom one from what the sketch looks like normally. Very faint planetary nebula that is detectable.  There are two bright stars interacting on the Planteary.  Appears to have structure and some brightening at times on the SW side of thePN.  Challenging object. 


2. Cassiopeia A, SNR in Cassiopeia.  September 27th, 2016 @ 10:40pm MDT; FR006 Juniper Grove; Antoniadi I, clear and cool, 48 degrees F; 17.5" Dob Star Catcher, Paracorr Type II; 22mm Nagler T4, 26mm Nagler T6; Thousand Oaks Filter OIII Filter.  Used 12mm and 17.3 Delos as well. 

Went to M52 then to the Bubble Nebula and then to a small asterism of a triangle and from the left corner up 3 stars in a row, and started looking.  The OIII popped this SNR right out of the background to me.  My friend Alan who confirmed the observation it took a minute for him to see it, but then it popped for him.  The SNR has faint whisps in it. It is thicker that I thought it would be with bright points embedded in it as well.  A wonderful and tremendously fun object to observe and rather easy to find with the right finder chart (see my SNR Challenge in my July 27th, 2015 post). 





3. NGC 7023 the Iris Nebula, a Reflection Nebula in Cepheus.  September 28th, 2016; 02:15am MDT; FR006 Juniper Grove; Antoniadi I, clear, cool 45-48 degrees F; SQM-L 21.8; 17.5" Dob Star Catcher; 22mm Nagler T4; 10mm Pentax XW; Paracorr Type II; Thousand Oaks OIII and UHC Narrowband Filters. 

Very evident reflection nebula that is worth the hunt.  I had tried twice before to obtain but was not reading the lay of the stars correctly in my star hops (doh!).  Prominent nebulosity around a mag 7.5 star, maybe 7.4 mag. Nebulosity is extensive around the star with a dark lane evident. Very fun object to observe and sketch. 






4. NGC 7217 Spiral Galaxy (Face On) in Pegasus; September 27th, 2016; 09:13pm MDT; Antoniadi I, clear, cool 50 degrees F; 17.5" Dob Star Catcher; Paracorr Type II; 22mm Nagler T4; 10mm Pentax XW.

This is a wonderful and bright spiral galaxy. When I took the image of the sketch some of the pastel chalk and come off and there is a brightness to this object not captured here but I have since added the pastel back to the sketch, sparyed an protective spray over it and I'll have to retake it.  This is a face on sprial with a bright small core region, with a stellar nucleus, with structure in the arms as it slowly brightens as you move in from the outer arms in to the core region. I highly recommend observing this wonderful galaxy.


5. NGC 40 Planetary Nebula in Cepheus; September 27th, 2016; 09:55pm MDT; FR006 Juniper Grove; Clear, Cool; 17.5" Dob, Star Catcher; 22mm Nagler T4; 10mm & 5mm Pentax XW; sketched at around 400x; OIII, H-Beta, UHC Thousand Oaks Filters; 

Wonderful object that I revisited. The PN is slightly elongated. At lower power the H-Beta gave/provided a better view then the OIII.  Higher magnification with the UHC filter is the best view. At 400x plus the east and west rims were brighter with the central region is darker with a bright 11.5 mag central star. Ring shaped structure seen with fainter spherical envelope with averted vision that I imposed in the background of the sketch. 


6. NGC 7354 Planetary Nebula in Cepheus.  September 28th, 2016; 12:15am MDT; FR006 Juniper Grove; Antoniadi I, steady skies and cool and clear; 17.5" dob Star Catcher; 22mm Nagler T4; 10mm, 7mm & 5mm Pentax XW; SQM 21.7; Thousand Oaks OIII and UHC filters. 

Faint planetary nebula that is mostly roundish in shape, though some irregularity in the disk is seen on the eastern-north-eastern edge.  Ring like structure with the edge brighter in spots. Filters did not bring out any more contrast or structure. It was actually better viewed with no filter at a dark site. 


7. NGC 7448 Spiral Galaxy in Pegasus. September 28th, 2016, 1:25am MDT: FR006 Juniper Grove; Antoniadi I, clear cool; SQM 21.8; 17.5" dob Star Catcher; 22mm Nagler T4; 7mm & 10mm Pentax XW; Paracorr Type II.  This galaxy is a well defined oval in the N-S direction.  It has a bright surface brightness and a bright inner core region, and is slightly opaque with some granularity, and is fading slowly at the edges.  It is a fun galaxy to observe! 


8. NGC 7457 Elliptical Galaxy in Pegasus; September 26th, 2016; 09:45pm; FR006 Juniper Grove; Antoniadi I, clear and cool; 17.5" dob Star Catcher; 22mm Nagler T4; 10mm Pentax XW; Paracorr Type II. 

Small but very bright elliptical galaxy. Edges fade into the background with brightness increasing as you observing the inner core region. 




9. NGC 7457 Lenticular Galaxy in Pegasus.  Mag. 11.9, Size 4.1' x 2.5'. FR006 Juniper Grove; September 26th, 2016; 9:25pm MDT: Antoniadi I, clear, cool, 58 degrees F; 17.5" Dob Star Catcher; 22mm Nagler T4; 7mm & 10mm Pentax XW; Paracorr Type II.  

Oval shape galaxy that is elongated ESE-WNW.  Bright and the central region is also elongated somewhat like a bar.  Fainter disc that fades in the sky background is evident. Nice object. 











10. NGC 7479 Barred Spiral Galaxy in Pegasus.  September 26th, 2016; 11:35pm MDT; FR006 Juniper Grove; Antoniadi I, clear, cool; 17.5" dob Star Catcher, f/4.4; 22mm Nagler T4, 7mm Pentax XW; Paracorr Type II. 

One of my favorite galaxies to observe each fall.  I last sketched this on November 2nd, 2010 using my old XX14i at Pit n Pole.  You can see that sketch under the new one for comparison. The darker location and the slightly larger aperture did make a difference. This galaxy is rather bright, and is elongated N-S with a bright bar on the major axis that has a slightly brighter bulge in the center.  The envelope is seen tonight and is hazy and diffused. The thin curving spiral arm on the south end curving to the west is evident. The second arm also is visible. Both are easily held with averted vision. 



11. NGC 7635 The Bubble Nebula; September 26th, 2016, 10:25pm MDT: FR006 Juniper Grove; V. Mag. 10.5, size 15'x8'; Antoniadi I, clear and cool; 17.5" dob Star Catcher f/4.4; 22mm Nagler T4; 14mm, 10mm Pentax XW; Paracorr Type II; Thousand Oaks and DGM OIII, UHC filters. 

The Bubble Nebula shows on a portion of the actual bubble. That segment is north adn center of the brightest areas and adjacent to the 8.4 mag star SAO 20575.  The segment of the Bubble curves towards the east. OIII and UHC filters only improve the view slightly be they DGM or Thousand Oaks. 



12. NGC 7741 Galaxy Spiral in Pegasus; September 28th, 2016, 12:55am MDT: FR006 Juniper Grove; Antoniadi I, clear, cool; SQM-L 21.8; 17.5" dob, Star Catcher; 22mm Nagler T4; 10mm & 5mm Pentax XW; Paracorr Type II. 

Large and ill defined oval galaxy that lays E-W.  Bright moderate core region. Possible arms seen norther one confirmed as it heads south.  The southern arm is harder to see and hold.  Both need averted vision and dark skies to see. Arms hold with averted vision for 2 to 3 seconds and then fade, then reappear.  Double star impacts the view. 




13. NGC 7769 (face on Spiral in the middle); NGC 7771 (elongated spiral in upper left) & NGC 7770 the small and bright spiral next to NGC 7771.  Galaxies in the constellation of Pegasus.  September 27th, 2016, 12:00am MDT: FR006 Juniper Grove; Antoniadi I, clear, cool, 48 degrees F; 17.5" dob, Star Catcher f/4.4; 22mm Nagler T4; 14mm, 10mm Pentax XW; Paracorr Type II.  

NGC 7769 is a face on spiral galaxy that is round in shape, and large and bright.  The galaxy has a bright inner core region and a sharp stellar nucleus.  It is the brightest of the 3 galaxies.  

NGC 7771 is a rather bright and elongated galaxy that lays WSW-ENE.  The galaxy has a bright inner core region and maybe a faint nucleus. 

NGC 7770 is a bright, toss up between oval and slightly elongated galaxy.  It has a bright inner core and bright stellar nucleus.  

I need to update my Sky Tools 3 Library this week and then will post here the other 21 objects I observed but did not sketch. That made for a two day total of 35 objects.  

Oh, one more I guess. I did another attempt on Messier 31.  I am not overly happy with this new sketch nor with the end result regardless of how I adjusted the light to take the shot or to be honest in my sketching of the object. Too rushed, and. I was too tired and do not like how it came out. I'll post to show that yep, it happens, sketches we don't like (to be honest I am having more of them these days). Guess that means I get to try, try, try again! I'll post the three images I took as I tried to black the image taken and then the one not darkened or manipulated and the one from 2013 which is on the bottom. 





Above is the one from September 28th, 2016 and below is from fall, 2013.
