Gamma Velorum Obs report + sketch 19/1/10

[orestis]

Hi everyone,

I noticed that on one of my charts it showed that gamma velorum was a double star so i thought i'll have a look and i'm glad i did because it was a beautiful star system.I also did a sketch.

Gamma velorum star system -138x :Bright Blue-white primary with the secondary being a little fainter but of same colour.At right angle to the secondary was another double star system but fainter they were both of white colour.This was an atractive star system in a great field of stars.The primary star had small diffraction spikes.

Sketch details - I drew a 50mm circle on 110 gsm white paper and then plotted the stars with a #2 mechanicl pencil.I then put it Through gimp inverted it,added some colour and made the stars look round and here is the finished sketch.

I had lots of fun making the sketch.hope you like it.

Happy viewing

Beautiful work Orestis! The work in Gimp certainly adds a professional touch. Sketching also helps concentration, making you observe better, taking your time: rather than rushing madly from one object to another. I would rather see a dozen objects well than forty, as if there was a race.

Thanks Paul,

The work in gimp certainly gives it a profesional touch also i think it is more realistic to the actual ep view.

Sketching is also FUN.I think anyway.

Beautiful work Orestis! I haven't checked out Gamma Velorum yet, must start doing more doubles.
Nice sketch, I admire your patience and dedication.

another great sketch Orestis, i sketched gamma Leporis myself last week as its on a bino observing list I am working trhu..there is lovely around colour about the secondary on this one ..a striking orange colour

what instrument have you used for the sketch

[orestis]

Malcolm-Thanks,There are plenty of doubles out there i myself am now going to observe more doubles.I love double stars.

Daniel-Thanks daniel,Can you post your sketch so i can have a look if you don't mind.Sounds like a nice double,i have put it at the top of my observing list thanks can't wait to sketch it.I used a 130mmx900mm Reflector with a 6.5mm ep.

Thanks for sharing that Orestis. I've tried a little sketching myself and enjoy it immensely. Yours looks very professional. At the risk of sounding thick, what is gimp?

Thanks molly and Jethro,

Here is a labelled sketch for those who want to know which star is which.

The primary star Regor as it is commonly known is actually itself a spectroscopic binary With it being a Blue supergiant of spectral class o9 and its very close companion at a distnace of only 1 au is a Massive wolf-rayet star,the heaviest known.The binary has a orbital period of 78.5 days.

Regors next nearest companion (Gamma velorum B)is a blue-white B-type subgiant it is seperated from the Wolf-Rayet binary by 41.2''.

Gamma velorum has several fainter companions.The magnitude +8.5 Gamma velorum C a white A-type star which is 62.3 arcseconds from the primary Regor.

Gamma velorum D a A-type star of +9.4 magnitude is itself a binary system but its companion is 13th magnitude and i was unable to see it.

G'day mate,
Thats pretty clever stuff there and a good obervation report. I am going to go take a look see myself tonight. Keep up the good work

[Paddy (Patrick)]

Good report and nice sketch, Orestis. I might have to try this gimp program with my sketches. Yours are coming out very well. But I suspect that you are a pretty good sketcher to begin with.

[orestis]

Thanks Rom and Patrick for the kind comments,

Patrick-There is a tutorial on how to use gimp to digitize your sketches on http://www.perezmedia.net/beltofvenus/archives/000567.html .
To plot stars you don't have to be an artist.Could you pm me some of your sketches i'd love to see them.
