Celestron Power Seeker 80 AZS. Testing prime focus photography


I have had a chance to test the prime focus performance of the Celestron powerseeker 80 AZ..
To connect a DSLR camera, you simply attach a t-ring to the telescope focuser..There is a t-thread on the scope, so no need to buy a t-adapter.
A photos below are unedited and not cropped / sharpened in anyway…Camera settings were 400 ISO , 2.5MP on AE.

Image one was taken through my own Tamron 70-300mm @ 300mm at f8.
Image two was taken using the Celestron 80 AZ..This makes is a 400mm f5..The image is a little softer than the camera lens..But no doubt if I used magnified live image, and sharpened up in editing the results will be much better.The difference in magnification between the camera at 300mm and the 400mm of the scope is obvious.
Thirdly I took a more distant target to check for vignetting. There obviously is some, but this can be cropped out in editing..Great news is that unlike some refractors, no extension tube is needed.

Summing up. It is not a high end camera lens, but for the money is an affordable compromise..Should be ideal for wide field astronomy..Much better optics than the travel-scope 70..Just a shame it wont fit on a camera tripod or EQ mount unless you can fit tube rings..So you are stuck with the very capable celestron one..No image stabilisation , so a remote is a must have..

Available to buy from Northern Optics
