M15 in Pegasus

Messier 15, a globular cluster in the constellation Pegasus

Hi friends,
I want to introduce you one more of my drawings in high polluted sky. This time is the turn for M15. Despite of the blurred view, from the center of Madrid you can distinguish several bright stars in the center with a shape that tends to be square.

Object Name: M15 – NGC 7078

Date: October 20th 2014 22:00 h.(CET)
Temperature: 17 ºC
Seeing: 4/5
Telescope: Celestron nexstar 5′ S/C.
Eyepiece: 25 mm celestron

Clear skies!!

Globular Cluster in Sculptor

NGC 288, a globular star cluster in the constellation Sculptor

Globular Cluster in Sculptor

NGC 288 (Melotte 3) is an old, low density (class X) globular cluster not far from the south galactic pole. Less than 2° to the northwest is the famous bright galaxy NGC 253. The visual magnitude of this cluster is 9.4. Stars are visible across the front of this globular and I suspect some are foreground stars and not members of the globular. The view was pleasing and improved over the hour I spent observing and sketching this globular cluster. This target is 28,700 light years distant. At R.A. 00 hrs. 53min. and Dec. -26° 35’ this cluster is not a good one for light polluted skies back home in Chicagoland. Here in the dry night air of Arizona the transparency makes this a fine target.

The image offered by this huge and remarkable cluster is, for me, the most rewarding of heaven.

Quietly watching him with binoculars is a pleasure.

Caroline’s Rose

Hi,

Please accept my sketch of NGC7789, Caroline’s Rose. It is a wonderful open cluster in the constellation Cassiopeia. This is one of my first objects sketched for the Astronomical League’s new sketching observing program. The program requires you to make 75 sketches from a list of about 114 objects. The sketch was made from a fellow club member’s observing field near Green Bay, WI using my 10” Discovery Dobsonian telescope at 80x. For those of you belonging to the AL, I would highly recommend you taking a look at this program. For this sketch I used white paper with HB and 2B graphite pencils and blending stumps to smooth. Image colors were inverted using Paint.NET. I hope you enjoy it.

Object Name – NGC7789
Object Type – Open Cluster
Location – Near Green Bay, WI US
Date – 9/23/2014

Open Cluster NGC 6940 in Vulpecula

NGC 6940, an open cluster in the constellation Vulpecula

Greetings to all the ASOD community, I share this sketch of a fascinating open cluster in the constellation Vulpecula. It is amazing the eyepiece, lots of stars of various magnitudes with asterisms of all forms in the imagination and also a double star, all accompanied by the gaseous layer that surrounds the star cluster. Very good image even at low power.

Best regards.

M22 – the quietly spoken big brother globular cluster

Messier 22, the great globular cluster in Sagittarius

Hi all,
This was the second sketch I completed at this year’s Astrofest back in July.

M22 is a true jewel of the night sky. This giant globular cluster from a dark site it can be a naked eye object as well. It is large enough for even smaller telescopes to resolve its multitude of component stars, revealing its large and intense core.

M22 is beautiful in my 17.5” scope. It is very different from Omega Centauri and 47Tuc – could even describe it as the ‘runt’ of the giant globulars as its core is not as busy as its bigger brothers. But the component stars of its core are absolutely brilliant, arranged in so many signature patterns. It is slowly turning into a favourite of mine with its understated brilliance, loud without being overbearing presence, and sitting on a magnificent carpet of the Milky Way glow.

I won’t say much here. I’ll let M22 do its own quite whispering of its magnificence. Yeah, I think one firm fav of mine now…

Alex.
