A week or so I good I did some preliminary research for a decent 32mm eyepiece. Looking at my results today I went for budget but decent.
I have ended up with a shortlist of: -
Revelation 32.0mm Plossl Eyepiece 1.25"
Celestron 93323 1-1/4-32 mm Omni Series Eyepiece
Baader Planetarium 32 mm Classic Ortho Eyepiece
My query today as I recheck my findings is the Revelation one. That is coming up at almost half the price of the other two (at www.telescopehouse.com)
But this eyepiece made my shortlist due to positive comments about the GSO build.
So, finally, my question, does the purchase price suggest this 32mm isn't a GSO?
No rush here. It's a wish list not a need list - as I remind myself... lol
So the little circular bubble level is weak.
But how to improve the levelling stage a head of the alignment stage?
A traditional level like this one
Or a simple multi purpose one like this one?
And we do this on the tripod before adding the mount & OTA?
The mount looks gently curved. How do we check that for level or do we trust the ‘fit’?
I’m attempting to get back into astronomy, previously owned a 150pl reflector but parted company with it several years ago, I like the idea of a Cassegrain style as one of the big factors Of letting the 150pl go. was storage and transportation of It! I am interested in mostly visual observations but would look to take a few pictures here and there OF planets and easy nebula/DSO., I feel that a Schmidt-Cassegrain would be the best suited, my main stumbling point is should I get the 5 or 6 version. Is the 6 under mounted? And is it worth the extra cash, obviously there’s a higher light gathering power on the 6 but would it be much better than the 5, I see that the % of lens obstruction on the seems high! As the secondary mirror looks to be the same size on both 40% vs 14%! Obstruction by area. Any guidance would be very appreciated. I’m not against the idea of upgrading the mount in the future to a eq5 maybe? But want in usable to start with.
Hi. Its been 12 days of lockdown here in New Delhi, India. Gave me some quality time to spend on my childhood hobby. After a long time, I pointed my 10" Dob towards the Moon. And surely it does not disappoint. Its always a pleasure observing its surface. Observing it through eyepiece was a hair raising experience as I moved from 25mm (48x) to 6mm with a 2x Barlow (400x). Later I connected my dslr to the scope and took some quick pictures attached below.
Also took a video. Here's a link to my google drive. Please excuse me for the background noise that is there in the video.

Recently I observed profiles of hydrogen Balmer lines in Sirius spectrum with spectral type A. I used LowSpec spectrograph with 1800 l/mm diffraction grating and APO APM 107/700 on HEQ5 mount.
H-delta & H-epsilon:
I had some problems with stacking, so I used the best single frames in analysis.
