Obs Report 4-8-10 + sketch

Hi everyone,

Got a couple of clear nights this week and this was one were i had a great time.

Antares-Splitting this star is often regarded as being difficult to separate and after numerous attempts i was determined to splitthe star at 276 X i could still not see it so i popped in another barlow and at 553x
i saw it a tiny dot of green amidst the bubbling light of it brighhter companion.I did a sketch (attatched).The theoretical limit of my scope is 250x and i did double that.

Variable star observations

Lately i have taken up variable star obseving and i have decided to start off small.i started observing Beta lyrae an eclipsing binary.
On the 1-8-10 i estimated it to be 3.6 on the 3-8-10 i estimated it to be 3.4 and on the 4-8-10 i estimated it to be 3.3 and i will make an observation tonight if it will continue to rise or go back down.

Thanks for reading
Regards Orestis

An enjoyable read Orestis, thank you.
I too have been wanting to have a go at splitting Antares, so your report is sure going to help me. Wow, I didn't realise it would need that much power! I will give it a go next time I have clear skies.

All the best with your variable star obs, I know you will do very well.

Orestis your sketch is brilliant.
You have the same size scope as me but I don't have a barlow as yet so can't get the required magnification to do the job, not to mention the bad weather we keep having here in Melb.
Well done.

thanks for the comments,

Suzy-It all depends on the seeing it was pretty good the other day but it was still flickering and i tried at lower power and i just couldn't see it,so trying higher mag helped me.But since you have a 10'' dobsonian it has greater resolution than my scope so maybe you wont need to use as much mag as i did if you have good seeing.

regards Orestis

Excellent work Orestis! Congrats on the variable star observations too - as you continue, plot the magnitude against time and you'll have your very first light curve!

Cheers -
