Since alot of ppl like space themes, I figured why not open a "RL Space" thread.

Since this often starts with a small telescope, here is what you can REALLY expect to see:

An X3 solar flare has erupted from the Sun just a few hours ago. Not sure if it was Earth directed. More info to come in from NASA Solar Dynamics. It's been a very active solar cycle in the past week.

https://lh6.googleusercontent.com/-499lnfheNIM/Unmhb2dZqXI/AAAAAAAAJSI/yO8x-mX25rA/s426/13%2B-%2B1




Solar Maximum seems to be reaching it's height of activity. It's predicted that the Sun's magnetic field will flip as Maximum reaches the middle of it's active cycle.


I think it is only a matter of a few weeks until some random drama apocalyptic sect will spawn off these news.

I'm interested in Astronomy as in "I like watching science shows about stars, planets, other celestial objects, how they interact" and so forth. I'm really fascinated by that stuff and deeply impressed of what our current scientists & technology is capable of detecting & determing. Unfortunately my own scientific knowledge is way too low to involve myself more actively otherwise.

Planetary focused, this may be an interesting overview, it also shows the crazy progress since the 16th century.

On the science part, there have also been great achievements, you may want to watch this playlist:

In wake of Comet ISON due to become a Sungrazer I wondered how many FHC are interested in things beyond earth.
If you were not aware, ISON will almost crash in the sun in a few weeks and most likely create an effect so bright it will be visible in daylight.

@dpidcoe, a summary:

Generally, one needs to decide WHAT he wants to do. Usually, the limits are following and you can pick two:

- Cheap, Good, Pictures

You can indeed get cheap and good, but you will be limited to visual observations. I would suggest that WHATEVER you do, start with that.
You can also do Pictures RELATIVELY cheaply, but a) they will not be good and b) they will not be of anything "deep space", that is outside our solar system.

The big Q on WHY this is the way is easily answered by the way our earth roates around itself. The rotational axis (tilted too) leads to rather significant movement of Planets (the fastest) but also the sky.
Why is it not possible to take pictures will be the first thing you may ask yourself.
Since "Deep Space" relies on long (dozens of minutes to hours) of exposure, just a SLIGHT movement off the scope will yield a blurry and smeared picture as the sky is moving. So how do you take long exposure pictures of the moving sky?
Ze Germans invented the so called "German Equatorial Mount", a system that aligns the movement axis of the telescope not with the surface of the ground you stand on but the rotational axis of the planet. Since the speed of earths rotation is constant, we can have a motor compensate for that very precisely along the rotational axis, allowing for a telescope mount that "moves with the sky".
This is the #1 cost driver in Astrophotography and the reason why that is not a topic for "beginners". http://starizona.com/acb/basics/equip_mounts_gem.aspx

But! Not all things are lost. Visual Observations of Deep Skyp objects are "affordable" thanks to "Dobsons". Telescopes are like Engines, you can not replace displacement of an Engine with anything but more replacement, the same goes for Telescopes and their aperture.
Dobson is a "cheap" mount that allows for MASSIVE aperture for cheap budgets.

To Put things in perspective (not counting camera cost as it would be the same for both):

An "ok" Newtonian Telescope with an "ok" TrackingMount (150mm Skywatcher Explorer and EQ5 SynScan Mount) will easily cost EUR 1.000 and take pretty bad Pictures and "only" show this Visually:

http://www.binoviewer.at/beobachtungspraxis/images/m13_150750.jpg
http://www.binoviewer.at/beobachtungspraxis/images/jupiter150750_180x.jpg

http://www.teleskop-express.de/shop/product_info.php/language/en/info/p3939_Skywatcher-Explorer-150PDS-on-EQ5-Synscan-GoTo---Telescope.html

A 200mm Skywatcher Dobson will cost a mere 350 EUR and show you this, for 1/3rd of the price, with the only limitation that you can not take long exposure pictures. Notice how the deep space object benefits alot more from the aperture than the planet.
http://www.binoviewer.at/beobachtungspraxis/images/m13_2001000.jpg
http://www.binoviewer.at/beobachtungspraxis/images/jupiter2001000_180x.jpg


http://www.teleskop-express.de/shop/product_info.php/language/en/info/p1992_Skywatcher-Skyliner-200P---Classic-8--f-6-Parabolic-Dobsonian.html


Now, if even the "typical beginner" 200mm Dobson is too much cost wise to start, no worries, you can easily start under 80 bucks. There is a pretty nice "cheap" dobson of the 76mm size available from Celestron, the "Firstscope". It is great if you want to play around, take first steps and have a good start. The only downside is that you WILL need to buy a good eyepice for it (25 EUR, but can be used for other telescopes).
Of course, the pictures may not be hubble-Esque but Jupiter with moons and deep-sky objects are visible already:

http://www.binoviewer.at/beobachtungspraxis/images/m13_60700.jpg
http://www.binoviewer.at/beobachtungspraxis/images/jupiter40x.jpg

http://www.teleskop-express.de/shop/product_info.php/language/en/info/p2640_Celestron-Firstscope-76---76-300mm-Beginner-Dobsonian-Telescope.html

I hope this gives a good context.

And just for random hilarity, illustrating the price of a "upper midrange" astrophotography setup:

4.290,00 EUR EQ8 Synscan Mount
1.955,00 EUR 10" f/8 Ritchey-Chrétien Astrograph
2.917,00 EUR Atik 4000 Large Format Cooled CCD Camera
1.500 EUR Guider, Powerpack, Filters, random crap

I love the imagery but for some reason I've never gotten into the photography craze myself. I rock like a G10 4/3rds since it was an Xmas gift. My dad has been bitching about solar maximum as it royally screws with this HAM radio capabilities.

For space kicks I'd recommend going to KSC. They always have NASA staff around. In august has a proper geek out with some of the former Atlantis dudes and a communications expert.

dpidcoe: yes, but you do not take planetary pictures these days, you will usually take videos and have software use the thousands of frames to calculate the atmospheric intereference and calculate it out.
You can see this video here showing the DRAMATIC effect this has, it shows the video and the final "image" http://www.youtube.com/watch?v=YNgmpeEjwCI

Is it possible to buy filters or detectors allowing one to do astronomy in frequencies transparent to clouds?

In particular I wonder if I could use some kind of CCD to do ultraviolet astronomy on cloudy days?

Some basic reading seems to tell me that both IR and UV are not just scattered by cloud cover but emitted (in the case of IR) and reflected(in the case of UV) such that neither is really appropriate for straight forward observation.

Any thoughts on cloudy night viewing?

Speaking of things blowing up in space; http://phys.org/news/2014-06-physicist-slower-thought.html

The SN 1987A event had an unexpected 4.7h delay between neutrinos and photons. A new theory has been proposed which takes into account vacuum polarization where, during the brief moments the photons splits into a positron and an electron, the effect of gravity changes with the particle change.
