Use of Barlows and Powermates with astrophotography
Hi Guys,
It feels like a stupid question because whenever I google it I never get a straight answer.
Can you use a Barlow or a Powermate for astrophotography with a DSLR?
For example using a 80ED with a 2x televue powermate and then the T ring and DSLR.
Also, if you can is there anything that a beginner should know about the advantages/disadvantages of Barlow vs Powermate?
Thanks, Matt
