Hi everyone


I have recently acquired Meade LPI and this is my first go at the Saturn you can just about make it what it looks like. Can anyone suggest anything how to improve it, I used LX90GPS 8" SCT and Meade LPI Imager with 2x Barlow.
Any help on where to start with it how to tweak things within, what is correct exposure times would help please.

Dam,
Exposure times vary with each setup.
Go as low as you can go to make out detail .
When you stack the image the details will appear and it will get a bit brighter.
The rest is in post processing to get the final detail and brightness.

Great stuff Mark,

I will try that as soon as I get clear sky :-[, but I got another question.
How many images do I need to take and in what format do you save them to get best results?
Right now I save every composite image in jpeg. But alos I have noticed there are different formats that you can save, I don't know if that will make any difference.

Try taking about 200 images in bitmap.

It looks a bit over exposed. I'd try more frames per second and if you have a big enough disc on your PC don't use JPEG but TIFF or a less compressed format.

There may be some nice images of Saturn about but I failed to get a single image last year, so its not always that easy.

I don't have an LPI but the same issues apply.

Hi Philip,

Thanks for the tip, I will try it next time I go out as of now there is no clear sky at all in UK  :'(, however I have manage to get few images not long ago as we did have one decent night so I thought to make most of it and by trying few things that have been suggested I came up with this image. It looks better then first one but still, details are not good enough.
