Sunspot Series

Location: Budapest, Hungary
Date: 25th July 2011 – 29th July 2011
Media: Graphite pencil used on white paper
Equipment used: 130/650 SW, 65x and 130x

I have made this series with almost a little miracle as the weather here in Hungary have been awfully bad for days now. Although I always had a few minutes better weather with the Sun is shining when I immediately went out with my telescope and sketched the sunspots. I was very lucky on 29th July, as there was no clear weather, only ‘almost’ clear, with a foggy vision. Now the changes are quite apparent, the spots and groups are changing from day to day a lot. Hopefully there will be more other spots in the next days.

Sun in H-Alpha, July 29, 2011

Witam!
This is my sketch of the Sun in h-alpha. Sketch was made with Lunt LS 60T.

First version of this sketch was made with minimal tooling. Sketch was scanned, the effect of granullation was leveled and smoothed.
Second version is similiar to the real look in h-alpha. I did it as best as I could 🙂

Object: Sun
Date: July 29, 2011. Time: About 4:40 PM
Place: Rzeszów – Jasionka
Equipment: Lunt LS 60T with SWAN 20mm

Media: Graphite pencil, tooling with GIMP2

Garradd in August

It was a next day with beautiful weather in this month. I looked up to the sky and I remind that we have a beautiful comet up there. I looked up into my telescope immediately and I started to sketch it. The comet looks as small blurred star and it has short tail, but it isn’t as light as coma.

Jupiter is my favorite planetary. Sketch was made using the Newtonian Telescope 130/900 which won thanks to obserwations of the planet. Seeing rate 7 / 10.

Comet Visits a Globular Cluster

Hi,

The other night a visitor to the inner solar system, Comet C/2009 P1 (Garradd), appeared to make its own visit to M15, one of the brightest globular clusters in the northern sky. I say “appeared to” because M15 is actually over 33 thousand light years distant.

Comet Garradd was beautiful to see as it glided past the glob over the two nights I was able to view it. The soft glow of the moderately condensed comet head contrasted nicely with the bright knot of stars in M15 as the fan shaped tail swept faintly to the southeast, a sight I’ve tried to reproduce with this sketch.

Garradd will be making more visits over the next few weeks as it travels past the constellations Delphinus and Sagitta and the Coathanger asterism. Catch it if you are able!

Southern Jewels

Hello

Here, out of the oven, my new sketch of the open cluster “jewel box”, the NGC4755, also known as Kappa Crucis.
This open cluster is located in the constellation of the cruise, or crux, a few arcminutes of the star beta Crucis.
The NGC4755 has a magnitude of 4.3 is to 7,600 light years from the sun and has an angular size of 10 arc minutes.
It is visible to the naked eye, easily viewed with a 10×50 binoculars.
It’s a pretty crowded and is a champion of the star party audience that occur below 25 ° south latitude.

Thanks
