I currently have a Canon T6 with a Opteka 500mm f8 lens ($87) that I use for lunar and solar photography. I recently purchased a full frame Canon EOS R and am thinking about getting a 800mm f11 Canon RF lens ($899). Will the quality on the new canon lens be significantly better than my Opteka lens? Is it worth the upgrade? Also, should I use my new full frame or my crop sensor (1.6 factor) to shoot? I want to get the best quality possible.
I always been fascinated by astronomy and finally purchased a celestron nexstar 8se. Setup went smoothly but I'm a little stuck on the lens. I attached the star diagonal to the telescope and focused in on an object. I was able to see a part of the leaf on the plant in my house and I attached a picture of that. Moving the telescope left and right allowed me to see other things. I then took out the 25mm lens and can see through that when not attached to the telescope. I can see my sandals and feet through the lens and attached a picture of that. I then inserted the 25mm lens into the star diagonal and that's where all hope gets lost. I see white (assuming that's my wall) and yes the cover on the telescope is also off. No matter where I move the telescope. All I see is white. I tried last night in clear skies and pointed towards some clear stars using the skyportal app to align but I didnt see anything except pitch black through the lens. I also played with the focus but nothing. Am I doing something wrong, I would think the 25mm wouldnt be so zoomed in that I cant see anything? Thanks for any help you can provide me. Looking forward to exploring!!
I continue my reports from observatories I have visited. This one is very special for me, I did my education in astrophysics at this place in the 1990s. My girlfriend and I took the car this weekend and visited Saltsjöbaden for a walk, only 30 km from where we live. We ended the walk up at the Stockholm's Observatory.
Some photos from this beautiful place:
One of the observatories at this photos is the astrograph which I already earlier had written about.
What camera would you recommend to use with my Celestron SCT 9.25” ?
I would prefer a proper astrophotography camera rather than a DSLR.
I already have a focal reducer and would mostly want deep sky if possible (although my telescope may be too high mag for that), but would also enjoy planetary.
Any advice would be great guys.
