A few snapshots of family and other.

My west coast granddaughter, Zoe with her 76mm Orion Telescope.  


My son, Chad, daughter-in-law, Tina, and grandkids.  Zoe is below, visiting a beauty Salon. 



Zoe and her Dad in California after a bit of face painting. 

East Coast grandkids:  L-R:  Anna-Grace, John-Winston, Isaac, and Elisha…



My wife Debbie, with a 1997 Orion/Vixen 102mm refractor, which allowed me to  see Sirius B 

Roger Ivester And Zoe

This is one of my favorite pictures from 2011.  Zoe and I were at the Red Rock Canyon visitors center, just outside of Las Vegas. 


“A moment in time” when I was able to have all of my grandkids together in South Carolina.  The vintage 60mm refractor telescope shown was a gift to the kids by a good friend.  


My two sons, Roger Chadwick (L) and Bradley Jason.  I’m really fortunate to have sons like these guys.  It’s difficult for them to get together as Chad lives on the East Coast and Brad on the West Coast.  A very special photo to me…


Hey…this is me, working on an astronomy article at the coffee shop on a cold day with light snow.

NGC 3184 – Galaxy in Ursa Major – Observer’s Challenge: April 2015

May 16, 2015

The following pencil sketch was made using a No. 2 pencil, a blank 5 x 8 note card, colors inverted via computer.  Telescope: 10-inch Newtonian Reflector.   image002 NGC 3184 – galaxy in Ursa Major Date: February 25th 2000 Telescope:

10-inch Newtonian reflector Magnifications: Sketch @ 57x FOV: Sketch 1º Transparency: Fair NELM: 5.0 Very low surface brightness, mostly round with a slight N-S elongation. The overall texture is very smooth with a brighter core, however, very subtle. A magnitude 12 star lies just to the north, possibly touching the galaxy halo. I was very surprised, despite the LSB, a fairly high magnification of 143x worked extremely well for a careful view of the central region. To the west at about 30 arc minutes is bright star, Mu Ursa Majoris. The 9.8 cataloged magnitude of this galaxy is very deceiving, as it appears much dimmer, due to the very low surface brightness. If the transparency is not good, this galaxy can be very difficult. Best observed from a dark site for sure. My first observation of this galaxy was in 1993. During this session the skies were much darker with a NELM of 5.8 magnitude. The galaxy was easy to locate, according to my notes, using the same 10-inch telescope. Light pollution has increased in my backyard over the past twenty-five years.

My notes from 1993: Low Surface brightness, mostly round shape with a brighter more concentrated central region.
