Hi everyone. I have a few questions to try and get the best out of my Cannon 500D with 18-55mm kit lens and 55-250mm kit lens. I have done a few shots of the Moon, Jupiter and some constellations. Recently i got out and got some ok pics of Comet Lovejoy and am trying to stack the with CombineZP. I have managed 1 ok stack but all the other attempts do mirror type images of stars and little squares appear as stars sometimes. Is this because i have moved the camera too far for the stacking program to work? Also i tried to use Registax but the program says the pics are too large and wont even start. What is the best way to reduce their size? What is the best Photoshop program to use also? Just lately has been a massive learning curve for me and photography and am keen to get the most out of the equipment i have. Thanks for your time
