Jupiter, Mars and Saturn - March 2014
Posted 22 March 2014 - 10:28 AM
Here are my latest astrophotos of the most beautiful solar system planets .
The photos were obtained in Maceió, Brazil. The telescope was a 10" newtonian with a no tracking dobsonian mount and the camera was the Asi120mc.
I accept criticism and suggestions!

About how many frames are capture versas stacked and in what time period?

Hi Preston, thanks!
I stacked 1000 frames in Jupiter, 650 for Mars and 2500 in Saturn. The time period for Jupiter was 3 minutes, Mars 2 minutes and Saturn 15 minutes.

Looking at your scope and setup of the ASI120mc, it looks like you have perhaps a Barlow and extension tube...
Would you be so kind as to explain this assembly?

Hi Preston, I don't use barlow. For obtain this magnification I use positive projection with a 10mm eyepiece Plossl generic. The distance from the sensor is 60mm.

Thanks for sharing.

Is there a way to calculate the increase in magnification via the 10mm eyepiece and the distance to the censor...I that would be the Chip and not the face of the camera, correct?

Hi Preston,you are correct. I still don't know the formula to calculate the magnification with positiva projection...
Hi, Alan. My eyepiece is a 10mm Plossl that came with the scope. The processing was only in AS!2, Registax and Photoscape.
This is the way that I attached the eyepiece+camera to use positive projection:
