^ Thanks, I was just reading about this, apparently photographers usually leave the aperture open for minutes or longer which allows for a lot more light collection. I have a lot to learn apparently.

Just me, but maybe consider a 4" achromat like the Omni 102XLT.  Great optics, affordable, f9.8, 1000mm f/l...and on a CG4 mount as well.  For a few dollars more you can motorize the mount for tracking.

I intentionally took those photos to represent what the objects looked like through the eyepiece. They aren't very long exposures.obin

I live in Suwon. I recommend that you better go to Yangpyeong or Yongin to see a few galaxies.

Yangpyeong has relatively good sky to observe. But, it would take around 2 hours to go there.

Yongin is closer than Yangpyeong. From my home, it takes 35 min to go to Yongin Football Center. Yongin FC shows a grade lower than Yangpyeong(forget about western sky for the terrible light pollution from Seoul). But you can see Eastern Veil Nebular w/ 12 inch Dob.

You might see a few nabulae or deep sky objects in Gwacheon. But even though you might find them, they won't show any spectables to you in such a bad sky condition.

I spent a year at Yongson, headquartered in Seoul, from 1978-79. Korea is a beautiful country. Maybe you could consider buying an 8 inch Celestron. It would be easy to set up where you live to view the brighter stuff, yet small enough to haul to a dark sky site. To see deep sky objects such as galaxies and most nebula, you need to get to a dark sky site. From light polluted skies, you can still see well the planets, brighter globulars and nebula, and a whole bunch of double stars. Double stars are fascinating with their variety, differing colors and separation of components.

Thanks photowriter, will have to check those locations out I assume they are in Gangwon-do. You are right Gwacheon doesn't have the best conditions in the world, still light years better than Seoul unless you're observing downtown. I don't know if you're aware of this, but Gwacheon has an observatory at the science museum. The experience wasn't my cup of tea because the guy running it didn't know English and my Korean isn't up to snuff, so I didn't know how to request to look at other things besides Jupiter and Saturn, seems like he had things set up just to look at the planets... The biggest telescope there looked to be 20" at least so if you're in the area you might want to check it out once. They managed to darken all the lights near the observatory so its about the best conditions you'll get anywhere near here. Unfortunately they won't let me take a private telescope on the property at night unless I have a ticket to use the observatory How clear are the skies in the Suwon area?Anyway, after doing lots of naked eye observations over the past two weeks and reading lots of posts on here and on other sites, I think I'm going to downgrade my location to white zone  Yes I had a day where it looked a lot better, but I don't think I can buy a telescope based on an anomaly.I've come to the conclusion that although opinions vary, the majority say you actually need more aperture in a white zone, so I'll be buying either an 8" 9.5 or 11" SCT. So I'm pretty much down to an aperture vs weight situation. I'm not a big guy about 125 pounds soaking wet, so anything over 80 pounds would be out of the question. IF the 8" SCT is 65 pounds total than that's still a lot so I think I'll live with carrying another 15 for the much better views I'll get.  If I can find a much lighter 8" say 45 or 50 pounds well then I think I'll take my chance on missing a little aperture.Any posts by experienced red/white zone people would be appreciated as well as advice on SCTs. Thanks.

Thanks for your post Gene. I wasn't here in the 70's, came here fairly recently, but I've run into a few people here who were there back then, and everyone says you wouldn't believe how much things have changed. There are neon lights everywhere and I think 40% of the population lives in Seoul now. I'd say at least in my area, most Koreans earn a higher salary than Americans do. They've really made a lot of economic strides.I'm excited to take a look at double stars I think those will be my first target if galaxies aren't realistic. If you have any pertinent advice on SCT's it would be greatly appreciated. Thank you.

Here's a short article on urban astronomy that I put together a couple of years ago:Stargazing from light-polluted locales can be quite challenging.  However, a fair number of celestial objects can be successfully observed from cities.  The Moon, the bright planets, bright binary stars, bright open and globular clusters, bright nebulae, and bright galaxies are all possible targets.A number of articles on the subject appear at http://www.astronomy...spx?c=ss&amp;id=152Tips on city observing are posted at the following sites:http://www.astroleag...n/urbantip.htmlhttp://www.skyandtel...cs/3303991.htmlhttp://www.astronomy.../Setup is ke...Urban astronomy is also discussed at these sites:http://www.dirtyskies.com/http://washedoutastronomy.com/http://urbanastronomer.blogspot.com/Books on the subject include <em class="bbc">Urban Astronomy by Denis Berthier and <em class="bbc">The Urban Astronomer's Guide: A Walking Tour of the Cosmos for City Sky Watchers (Patrick Moore's Practical Astronomy Series) by Rod Mollise.http://www.amazon.co...r/dp/052153190Xhttp://www.amazon.co...y/dp/1846282160Lists of deep-sky objects that are visible from urban areas can be found at the following URLs:http://mysite.verizo...55p46/id10.htmlhttp://www.astroleag...an/urbanld.htmlhttp://www.skyandtel...ts/3074841.htmlhttp://www.astronomy...2/Explore de...Dave Mitsky

AcesDJD,

I agree that at least Gwacheon is quite better than Seoul. But it is not enough dark to observe deep sky objects. You can find how bright Gwacheon are at  Dark Sky Map .

Suwon also is not good to observe deep sky. Past two weeks, the sky condition was fairly good. A lot better than usual Korean sky.

Anyway, it will be good to have a car to do observations. Yonging Football Center that I said is placed in Kyunggi-do. Yangpyeong is placed in Kyunggi-do also. Gangwon-do has better sky but it is too far from Gwacheon or Suwon.
