Astro Imaging

I have experimented with a range of imaging techniques. Here are some examples of my efforts.
At left is an image of the planet Jupiter. It was taken with a simple webcam on a 6 inch F/10 Newtonian. No guiding was used. Instead several frames were added together to enhance detail.
The pic on the right is Saturn and was taken with the same setup as Jupiter
Another image with this setup. A single frame showing the famous lunar crater Clavius.
The pic at left is the Double Cluster in Hercules. It is a single unguided 20s exposure taken with a Starlight Express 512 CCD camera attached to a 50mm fl SLR camera lens.
The two images at right of the Great Nebula in Orion, were taken with the same CCD camera, unguided on an 8inch F/6 Newtonian. They show the advantge of stacking multiple images. The top pic is 4 images and the lower used 14.
| have done some work also with conventional film. Unfortunately I don't have any of these pics in digitised form so can't show anything here yet. I will fix that.
In my opinion slides are far better than paper prints for chemical astrophotography. Firstly, it's cheaper. Only a developing tank, thermometer and chemical set are required. No need for an enlarger, paper, additional chemicals etc. Secondly it is easier and quicker. All the work is done in the tank and therefore no darkroom is needed. Thirdly, you can use a technique called slide duplication to greatly enhance the contrast and detail in the  original slide. This is not difficult. You just need a duplicator, which is a tube device that fits in place of the camera lens. At the other end is a slot to hold the slide you are copying and a diffusing screen to illuminate that slide uniformly. You hold the setup on a good tripod or firm surface and just take a slide pic of the original slide. The results can be stunning.
