Having previously got some reasonable images by mounting a smart phone to the eyepiece. I thought I would try for a more sophisticated set up.
So last night I tried to get some pictures of the moon using a Canon Eos D450 connected to a Skywatcher 130p Newtonian via a T2 connection on the eyepiece holder.
As the camera has automatic focusing built into the lens I thought I would have to adjust the focuser on the eyepiece holder to manually get a sharp image.
Basically the telescope acting as a manually focused lens for the camera.
But no joy, I just got a bright light which seemed to fill the camera view finder. I tried various settings on the camera, adjusting ISO and aperture etc, I also had some extention rings for the camera lens so tired fitting those to extend the focal length but no better.
I sure there are many palms being slapped against foreheads reading this but as you can tell I have no idea, although I do have some of the gear.
Any pointers and/or advise would be gratefully received.
Hi! I've been struggling to get rid of slightly spiked/elongated stars that appear on the left hand side of my images. The stars have small spikes coming out the bottom left hand side of them.
I use an unmodded Canon 600D with a 70-200mm Canon f4 lens (which I have recently cleaned to try and solve this issue). I use the star adventurer to track, but this doesn't look like the type of trail you get with bad alignment.
I've attached some images as an example of what I mean - Example 1 is the bottom left of an image of the North American Nebula, and example 2 is the top right of the same image. Any ideas?
These nebulae are located in the constellation Corona Australis, between γ and ε Coronae Australis and features NGC6726, NGC6729 and NGC6723.
This is not a popular group of objects or part of the sky, but I thought that the combination of reflection nebula crossed by a dark nebulae make an interesting image.
This image was exposed through my Celestron 8" SCT (at F10), on the CGEM mount with my full spectrum modded and cooled Canon 40D DSLR for a total exposure time of 5 hours, 59 minutes and 30 seconds.
I would like to share with you an article written by me on high-resolution solar imaging in different wavelengths. Glad that the European Physics Journal (EPJ) Web of Conferences published it. You can read it at:
You can see the different layers of the Sun in high-resolution images using different setups.
