Astronomy with a large helping of physics and a pinch of the other sciences.

Behold a few wonders of the cosmos: From top to bottom are galaxies M101, M81, Centaurus A, and M51. The images are a collaboration combining data from amateur astronomers and NASA mission archives. X-rays from Chandra are purple, infrared data from Spitzer are red, and the optical data are red, green, and blue. (Chandra X-ray Observatory)

tinseltowns asked: hi! i really love your blog! did you take he first photo post/96307311899/saturn-was-really-close-in-the-sky-to-the-moon through a telescope? how can i photograph the moon through a telescope? :)


Answer:

Thank you! I did - I just used the camera on my phone held up to the eyepiece of the telescope. The trick is to line it up right and make sure it’s in focus, but you get better at that with practice. There are better ways of doing it though: you can get adaptors to attach a proper camera to the telescope; I’ve also known people to use webcams. Taking a quick snap with a phone is probably the easiest way, and you don’t need much equipment. :)

This is the Andromeda Galaxy. I took this back in January and I re-processed it with PixInsight. I’ve got until October to decide if I’m going to buy it, and I think the decision is pretty much final. #astronomy #astrophotography #galaxy #andromeda #m31 #galaxy #space #stars #universe #cosmos #canon #6d

mattstartsomething reblogged your post Saturn was really close in the sky to … and added:

what phone do you have?!

iPhone 4S. It’s actually much easier to use than my actual camera when I’m trying to capture images through the eyepiece.

Saturn was really close in the sky to the Moon tonight! Here’s what I got with my ‘scope and phone camera.

This was my first real attempt at the Veil Nebula. I need a lot more data, but you can make out parts of it near the center. #astronomy #astrophotography #nebula #canon #60da #space #stars #milkyway #stars

I took a lot of pictures of Robin’s Tesla coil last night. I did some longer exposures and then some short exposures to get only a single spark while holding down the shutter to take continuous pictures.

We also stuck a radiometer on the top of it. The radiometer contains low pressure gas which emits light when current flows through it acting similar to a fluorescent light bulb. Here’s how a radiometer normally works.

The pictures I took of the radiometer vary in brightness because I adjusted the exposure on each picture. When we were watching it was a fairly consistent brightness.

In the upper-left you can see the Triangulum Galaxy. It’s approximately 3 million light years away, which is relatively close to us compared to most other galaxies. #astrophotography #astronomy #galaxy #60da #canon #135mm #135f2 #space #stars #science #universe #cosmos

So pleased that our findings from the 6.5-yr imaging survey I conducted with Cassini’s high resolution camera of the geyser basin capping Enceladus’ southern hemisphere made the cover of the Astronomical Journal! How sweet it is! [Scientists love this sort of thing ;-) ]

Went up to Mt. Washington last night. The sky was great! The trees were kind of in my way and there was also some annoying lighting but I worked with it

Calling all UoM students!

uomastrosoc:

Hi everyone!

I’m Emma, also known on tumblr as astronemma, and I’m ‘Science Officer’ of the University of Manchester Astronomy Society. This means I organise stargazing events and the like for the society, but I’ve also taken it upon myself to set up this blog. 

As a society, we organise many events to get involved with. These include: trips to Jodrell Bank; stargazing evenings; lectures on a range of astronomical topics by experienced speakers; camping trips to less light-polluted areas; and much more. We have a range of equipment including telescopes, but you’re more than welcome to use your own if you have it!

So, if you’ve been a student here at UoM for a while now, or you’re joining us in September, and you have an interest in astronomy, then our society is for you! We already have a range of members from a number of different courses, and have a mix of experienced astronomers and interested newcomers amongst us. 

Our Facebook page and group are probably the best way of keeping informed for now, at least until we get this blog and our Twitter feed up and running properly. We’ll also have a stall running at the Fresher’s Fair, so come along and say hello!

 - Emma
