TiTanecd Posted June 23, 2014 Share Posted June 23, 2014 HelloI have a Celestron 130EQ. I'd like to find out if newts will always have the secondary mirror obstructing your pictures / videos if you attach a device afocally or prime?I have tried both with a Canon A570 (lens is perma attached and cant be removed), cellphone and webcam. I'd like to know if its because these have lens attached that cause this, and a DSLR like a 600D, that you can remove the lens, if that will look passed the secondary mirror obstruction, similar to our eyes.Tx guys.

Leveye Posted June 23, 2014 Share Posted June 23, 2014 If you are referring to the diffraction spikes associated with imaging with a Newtonian with a standard 4 vane spider you can install a curved 3 vane one to get rid of most of the pattern. In America here i get mine from 1800Destiny. Check it. Link to comment Share on other sites More sharing options...
D4N Posted June 23, 2014 Share Posted June 23, 2014 When you say the lens can't be removed what I think your really saying is you don't want to trash the camera modding it? I'm sure any camera can have its lens removed with enough effort At prime focus you shouldn't see the secondary mirror as such, you should see what the scopes pointing at. The only way you would see the mirror is if you have a lens on the camera but then that's not prime focus anymore.

Tim Posted June 23, 2014 Share Posted June 23, 2014 You will need to focus the light in a different place to make that camera work, using an eyepiece, or use a camera/webcam without a lens built in.The secondary will always be there. Link to comment Share on other sites More sharing options...
TiTanecd Posted June 23, 2014 Author Share Posted June 23, 2014 Thnx I thought that the lens would be causing the secondary to be displayed.Don't really want to take the lens off atm, until I know I can (or allowed) , and have a bracket to month with.
