Sunspot #1023

Posted in Uncategorized with tags , , , , , , , , , , on June 23, 2009 by Andrew

I received a email alert from yesterday alerting me that the sun has a pair of new sunspots which are now visible.I was bit upset about this due to the fact that not only do I have very little time to observe but,we have been under a thick layer of clouds for the past month+ as well.Why is it that whenever we have a bit of space excitement Mother nature always seems to be a wet blanket?.I refer to having new sunspots as space excitement only because the sun has been spotless for such a long period of time.I have officially stopped listening to the local weather forcaster (as of this morning) because they never get the forecasting right.I went to bed lastnight with the impression that I would be waking up to typical cloudcover.When I awoke this morning I was quite thrilled to see absolutely clear blue sky!!! 🙂 .Once again the forecasters got it wrong but,hey I’m not upset.In fact I”m glad they screwed it up!!!.After I had my gallon of coffee (heh,just kidding….it was only a half gallon!),I quickly set my big scope up and faked the alignment.Gotta hurry cuz,my guess was that it would turn cloudy again and it did after a couple hours.With a few puffy clouds drifting past I was able to get quite a few images of the new spots only to delete them due to DIRTY LENSES 😦 .Hmmmm,well I did image spots,just not the type of spots that I was trying for!!.Thats right…I haven’t used the scope in such a long time that it had sadly become a dust magnet *crowd boo’s and hisses*.With little time to spare I performed a quick cleanup and managed to get a few more shots before the clouds moved back in.

According to these new spots are from new solar cycle 24..

From – The magnetic polarity of sunspot 1023 identifies it as a member of new Solar Cycle 24. Its appearance coincides with the movement of two solar jet streams into a range of heliographic latitudes that promotes sunspot formation. No one knows exactly how the sun’s deep jet streams boost the sunspot count, but they do. As a result, this week’s sunspot activity might herald more to come.

M51 (Whirlpool galaxy)

Posted in Uncategorized with tags , , , , , , , , , , , , on March 29, 2009 by Andrew

I managed to get the scope out for some observing a couple weeks back and was treated to some fantastic skies…Yaaaaaay!!!!!!!.The temps were were seasonable and in the mid to upper 20s F with calm winds.I was going to use my DSLR again but,since the temps were half way decent I used the Meade DSI instead.My thought was that I was going to image the comet with the DSI but,realised that it was directly over head which is good for imaging.Problem is,my scope will give me a alert that the OTA will come into contact with the tripod so,that idea quickly vanished.
Knowing that their are lots of other faint fuzzies to be seen I decided on observing/imaging Messier object #51 a.k.a the Whirlpool galaxy.As many of you know,observing this object from light polluted skies is next to impossible?!.In recent posts I have mentioned how different the skies are from my new location compared to the street observing I was used to.Well,M51 was a object that I had never seen with my scope but,still managed to image anyway.This observing night was well worth the time consuming task of setup and alignment (hope to build…or buy a observatory in the near future! ;p ) and the hoots of a distant Owl seemed like a approval for my decision.Hahahahahaha,actually it was a unsettling sound which made me think of a scene from some horror flick.I had a fantastic view of M51 which,appeared as a faint fuzzy gray patch.That was until I got the DSI centered and focused on it.WOW!!!.This galaxy suddenly went from fuzzy to showing alot of detail including the bridge of gas that is being ripped from it’s companion NGC 5195.
Because of numerous reasons i.e foul weather,work and family health reasons, I haven’t had a lot of time to really get to know the workings of the DSI or find the proper settings that work for my style of imaging…heh,ok I don’t have a style! 🙂 .So,if you see a problem with any of my images and know the solution to fix them,feel quite free to give me a friendly heads up.
Located in the constellation Canes Venatici,M51 (Whirlpool galaxy) is  60,000 light-years across and about 31 million light-years distant.It can be seen not far from the handle of the Big dipper which puts it quite high in the sky in northern latitudes and has a visual mag of +8.4 .
According to the SEDS,M51 is easy and a showpiece if the sky is dark, but is quite sensitive for light pollution which easily makes it fade in the background. Under very good conditions, even suggestions of its spiral arms can be glanced with telescopes starting from 4-inch. Low magnification is best for viewing this pair.
RA 13 : 29.9 (h:m) DEC +47 : 12 (deg:m)
