  1. Mhm, I felt like I had to post something in blogs, so here ya go...

    A little less that a month ago, I finally bought a new 6" telescope, my first one, not counting the 2" handheld refractor that I've had for like 10 years. The same scope is sold on Ebay here.

    A few days ago, my brother bought a digital Sony camera, so I decided to try some simple shooting through the scope's eyepiece. I've taken a few photos of the sky before, that was about 9 years ago, but I did 'piggybacking', used the scope just for compensating the earth's rotation while exposing. I don't have a photo adapter, so I just put the camera's objective to the scope's eyepiece and took the shots. So here they are:

    Moon at 30x magnification. This is the best one. Since the magnification was not high, the image was focused well and didn't move here and there much. It's my desktop wallpaper now :)

    Moon at 56x magnification. This is not as good, somewhat blurry, and reasons are clear: the higher the magnification, the more the image shakes because the atmospheric turbulence, and the handheld camera also moves a bit during the shot.

    Moon at 115x magnification. Bleh. Just one big blur.

    All three images of the moon were reduced to save webspace.

    I also tried shooting Jupiter and Saturn at 115x, but, as expected, I didn't obtain good images: absolutely no detail is visible in Jupiter, and even Saturn ring is barely visible.

    The next time the sky is clear, I'll try again at lower magnifications and camera's resolution set to maximum. I don't expect to get something significantly better but it will still be worth a try.

      Woah, cool pictures. I've got a telescope too, every once in a while I gaze at the moon. I've tried to find deep space objects as well, but of course my basic telescope won't do for that. I still wanna see nebula's and stuff.

      You haven't told your telescope specs but I'm pretty sure you could find a number of DSO's through it. I've seen quite a few of them through my aforementioned 2" (5 cm) handheld scope-let. Since the key to finding fainter objects is knowing where exactly they are, you may consider downloading a planetarium program, for example StarCharts, which is freeware and really powerful. You can also download additional star catalogs (with almost certainly more stars than your telescope can show), flip the view horizontally and vertically to fit that of the scope, online update and so forth. The main tip for finding an object would we to choose a nearby naked-eye star and then, using a program like StarCharts, memorize the star patterns that lead from the chosen star to the object. This is called starhopping. Now I can find many star clusters, galaxies and other objects in no time using this method, given that the sky is good enough and the object is bright enough to actually be seen. If the object is on the verge of being visible, you can use averted vision - don't look directly to it, but somewhere next to it, and blah, you see it!

      I really hope this will raise your enthusiasm at least for a little bit :)

      I hope so too, but unfortunately the neighbourhood had new lanternposts installed over a year ago. They pollute the sky. Such a shame. I'll probaby visit one of those observatories one day, to see the Andromeda galaxy from up close :)
