For various reasons, I find a correctly orientated image, (vertically & horizontally) as given by an Amici prism in a diagonal, much easier for me to use with my observing.
I absolutely loved the Baader Amici prism with the ClickLock. The build quality is lovely and it gave really great views - except when you try and use it on an object brighter than about magnitude 1.5, whereupon you see the infamous diffraction spike ruining your view.
I know this is a fairly common issue with prisms and with Baader Amici prisms in particular but I have also heard of people trying several and then finding one without the diffraction spike issue. Mine was bought from a reputable online only astronomy supplier on the USA west coast who assured me they tested the prism prior to my purchase but they obvioulsy did not. They did give me a refund in the end. I would really love to try and obtain another Baader prism but without the diffraction problem.
My question is, have you done the process of trying several prisms before getting a good one? Who did you use? (please feel free to PM me) Did you end going directly to Baader? I would do that ordinarily but I now live in the USA, not Europe. Have you another non Baader correct orientation prism that you could recommend to me ? (Although I have to say once you use a Baader diagonal with a ClickLock there really is no going back to the fiddly adjustment screws!!!)
Thanks for any advice, sharing of experiences or recommendations.
I have just got myself a Celestron C11-A XLT (CG-5) scope and a SkyWatcher EQ6-R PRO SynScan mount. I have an ASIAIR PRO and the ZWO ASI462MC planetary camera. I want to use my Nikon DSLR for deep sky photography.
Now I’m looking at auto guide options. I’m thinking of getting a ZWO ASI290MM mini and am wondering if I should get a guidescope or an OAG? Which is better and why?
I don’t have the Edge HD C11 so would the view on my scope be good enough for an OAG? If I go for a guidescope what would I need there? I’ve seen 50mm and 60mm scopes but some people have mounted huge guidescopes which would be way out of my budget. Would a smaller guide scope be up to the job?
Any advice would be greatly appreciated.
Baader Hyperion Eyepieces
5mm - £70
10mm - £70
24mm - £70
Or all three for £190
I bought these over on ABS a while back, used them a couple of times, and have never touched them again, so selling for future upgrade points.
They seem like perfectly OK eyepieces, but the Baader and TV zooms are perfectly good for my portable viewing, and take up less space and weight.
Price includes UK postage. Payment by bank transfer (preferred) or PayPal (buyer pays fees).
I'm trying to get a photo of Jupiter and Saturn with my Nikon D3000 DSLR but I can't get anything clear. I attached the kind of photos I'm getting with my camera. They end up being too bright and no distinguishable features show up. Is it even possible for my Nikon to get photos of planetary objects like Saturn and Jupiter?
I just got into observing and would love to be able to take a picture of what I'm seeing. I got an old Nikon D60 from 2012? laying here still working perfectly with multiple lenses. I did some research and found I should buy some kind of T-ring as an adapter between the telescope and camera. Is this the only thing I need to take an image ?
Thanks in advance!
