Hi, I am doing an end of degree project on variable stars due next thursday and London's weather does not allow finish it. I was wondering if someone would do me the favour of observing the pulsating variable star V0460 Andromeda http://variablestars.net/stars/460/ in the Johnson R filter, for a period of 1 hour and 50 minutes? please?
Thanks so much!
I recently got hands on my first equatorial mount, a Celestron Advanced VX mount.. And the curse holds true, that after purchasing new gear, you are to bear the burden of weeks of bad weather! So whenever there has been minor holes in the clouds, I've been out practicing star alignment, polar alignment, and just the general behavior of the mount, pointing at any star that would glance through the thin cloud cover. Hope to soon be able to practice drift alignment.
A patch of "clear sky" showed itself a few nights ago, so I thought I would try and see how far I could push the unguided exposures (having only done the ASPA). And even though thin clouds would regularly pass over the target, I am at least pleased that I could squeeze this out of the image. +- 1 minute exposures of the center of the noble M45, Pleiades. 5-6 shots later, the clouds came rolling in again... So here I am stuck looking at my mount collecting dust and browsing these forums again
Looks like there is some coma that needs fixing too.
Scope is the Celestron 130 SLT OTA. Using a barlow right now to achieve focus. Trying to obtain the screws needed to move the mirror.
As a bonus, I noticed the presence of a magnitude 17.2 in this one, faintest I've caught yet I think.
First thing this morning the BBC was showing me clouds for most of this evening. So no chance of any observing or imaging. A couple of hours later and low and behold it was showing clear from 17.00 to 23.00 - and FLO Clear outside was agreeing. Great I thought and started to make plans. Just about to move the powertank into the observatory when I looked again - there was actually a shower (not forecast) on at the time. Cloudy from 18.00 onwards - FLO not quite so pessimistic. Who know what will be predicted in another couple of hours. Indeed, the only reliable 'forecast' will be to look outside when it is dark enough to do anything and maybe see what they have to say then.
I have been a weather observer and data collector on an off for the best part of 60 years so none of this surprises me. Now that they have superfast computers which are updated at ever decreasing intervals. This means that any very small changes in wind direction will, if the weather is at all unsettled, result in completely different forecasts in terms of clouds and rain. And they are advertising 'Get the weather in your area'. I interpret that to mean that we want more money from you for yet more faster computers.
By stepping beyond
Well , let me start off with something went wrong with my mount . It just wants to take off and run when getting ready to image. I haven't a clue what's going on with it but, I'll figure it out one day . I had 7 straight glorious nights and now it's doing nothing but, rain. I'm sick , Ill whatever you want to call it , that's me.
I teach grade nine and ten (History, Science, Language Arts) in an isolated region of northern Quebec. Some weeks are more trying than others making this one the most straining of all. Last night, in an attempt to reconnect with my sanity (in the midst of correcting, lesson planning and science fair reports) I bundled up to face whatever mother nature had in store for me. I was in luck... the moon was center stage while the clouds had rolled out of view. Unfortunately, with the humidity at 80% and the mercury at -30 degrees Celsius, the visibility was quite poor. Ever seen the moon swim in frozen waters through your lenses? That's when humidity and cold create well... this:
My Telrad had given me issues the previous week so I was happy to see that it was now securely fastened with a screw. Serious deep space viewing was impossible due to the Waxing Gibbous moon and humidity casting an ominous glow. However, the moon simply couldn't be ignored. Taken pictures is not as important to me as being in the presence of such reflective splendor but I did catch this little picture with my Galaxy SIII. My students always enjoy it when I share it with them the following day.
I was surprised that none of my secondary students came to join me but with the Olympics on and the freezing temperatures, I can't blame them. Extreme astronomy isn't for everyone. I am very proud of one of my students who has taken the habit of making her way to my house every time the clouds cooperate. Unfortunately for both of us, these times are few and far between this winter. Today in class, she was able to conduct an experiment working with micrometeorites. She gathered snow shortly after the Quadrantids and with the help of a magnet discovered this little gem which she will be showing at the Science Fair next Wednesday. She understands that not every speck of rock that reacts with a magnet a micrometeorite. I told her that I would be posting it on this site and she is now awaiting your final say.. did she actually find a micrometeorite? The picture was taken through a microscope and then enlarged by cropping the picture.
Have a great weekend everyone and clear skies!
