How does our skin respond to changes in temperature?

Thanks for the link. But I cannot seem to find any variable stars with periods of only a few hours. I need to find some in the northern hemisphere so I can make real time photometric measurements.

Hey, What are the most common eclipsing binary stars and variable stars to observe with periods of a few hours? Im observing from Ireland. Thanks

I asked the question for a final year project. Now I was asking if it were possible to detect signs of a planet with the C11.

Hi there, Im wondering if it is possible to observe a known star that is known to have a Jupiter planet orbiting it, and analyse its light intensity to search for the planet with a Celestron C11 XLT and a CCD? Examining its spectra with some computer software. Its a thought for my final...

Oh yes I am well aware of Einsteins G.Relativity warping and bending spacetime. I just wasnt sure that if light followed the curvature of spacetime. But you made it clear now. Thanks!

Why does light bend when it encounters a black hole or a star? Does a black hole have a refractive index? It must depend on its mass if it does. A star can produce an effect knows as gravitational lensing which bends light in much the same way as an optical lens bends light, how does this...

That is what I always dreamed of going into after my education ie planet hunting. This is amazing! The problem is though I live in Dublin, and Dublin does not offer any high mountains to escape some of the atmospheric noise.. Is it still possible to observe from sea level? Also clear nights...

Hi there, I am entering my 3rd year of my physics degree and I recently purchased a Celestron 11'' Schmidt Cassegrain telescope. My lecturer advised me before the summer holidays to work on an area of astronomy/astrophysics for my final year project. Would anyone have any ideas on what I...

Is it possible to view nubulae and galaxies with the 40mm eyepiece without a camera and only a NexImager Solar System Imager?

Oh ok i thought so.

I received a 40mm plossl eyepiece with it. I have the celestron eyepiece and filter kit on order at the moment so I should receive it within the next few days. Can You name some decent eyepiece manufacturers for me? I also got the NexImage SolarSystem Imager and I downloaded Registax too...

Thanks for the links Russ, the Jupiter images look really nice. I had a nice peek at the crystal clear sky last night, but all I got with it was the star diagonal and a widefield lens. I observed Jupiter and two of its moons but it was quite small, I could still see cloudbands on it. I just...

Ok I got the Celestron 11inch schmidt cassegrain with XLT coatings and GPS with Star Aligner on the German Equatorial Mount. Pretty ******* Huge alright. This is my first telescope and I can see why you would be jealous now. hehe I cannot wait for the sun to set!

Hi there, I am purchasing a Celestron 11inch schmidt cassegrain with XLT coatings this week. But I have no become frustrated as to whether to purchase the C11-SGT (XLT) or the CPC 1100 GPS (XLT). I have come to the conclusion that the German Equatorial mount on the C11-SGT is far more...
