I am a big fan of the pixel size of the ASI533MC Pro (3.76), as it creates a practical image scale (resolution) when used with most of the refractor telescopes I use for astrophotography. The square image format may take some getting used to, but wider image frames can be achieved by...
When it comes to astrophotography, telescopes are often easier to focus than camera lenses. This is simply because telescopes usually have precision, robust focusers that lock into place. A camera lens designed for daytime photography, on the other hand, was meant to move quickly to accurately f...
Sirius EQ-G mount, Orion ST80 (80mm f/5 refractor). Results: Nice setup for easy EAA. Noticeable CA on bright objects, but still a useable rig. Now on semi-permanent loan to a friend. Then, last year at this time, DW bought me anASI294MC Procamera. Wooooohoooooo! Game changer....
maybe due to the cascade of influences. But, I think that has been my point all along, really, in the case of having a well made obstructed scope. The MTF curve may go up in places and down in places, but IMO the view is indistinguishable at those places it ...
A long focal length is required to capture close-ups of the moon A tripod or telescope mount may be required for your goals The “auto” function on your camera will not likely work on the moon A total lunar eclipse. Canon EOS R through a refractor telescope. ...
I have three different scopes, all with a different finding methods. I find all three to be very accurate. Celestron SE6 computerized go-to - For some reason mine gets very accurate slews all the time. I use two star auto align, but in the tablet it now requires three. I now have ...
The odd thing is that the stars are averaging just over 3 size using ASIAIR's auto focus routine whereas they used to be a little under 3. The results have looked just fine however. I like the fact that now I can pick a number value for my rotation. This is quite helpful as I ...
