I have a Motor drive for the 130EQ and when I attach and switch it on it drives the RA axis. But once its attached its very difficult to move the OTA in the RA axis manually. Am I missing something? Is there a way to easily couple & decouple the motor so the OTA can be moved manually?
Is there someone who uses one of these motors who can help me pls.
Hi everyone - juts purchased my first telescope and am asking for advice on what is best to be seen through this telescope as a starter - have already seen the moon and some distant stars and am comfortable with using all of the eye pieces included. What would anyone recommend?
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.
A question for all you Starsense users out there ...
When I do an auto align with Starsense, it duly goes through it's routine of moving the scope to different star targets and resolves each one fine (5 targets I believe). Then it displays on the handset "StarSense Ready".
At this point the telescope tube is always pointing in some random direction - is this how yours behaves after it finishes alignment ? Just pointing at the last star it used as a target reference ?
At this point I usually set my scope to go to it's "HOME" position, but whenever I "GOTO" a target it is never in the scopes eyepiece and I have to manually hunt around for it. (Using a wide angled eyepiece).
Should I just "GOTO" a target without going to "HOME" position first, or should it not matter ?
NB - All this after precise Polar Alignment using Polemaster.
Grateful for your input
I am looking into making a hobby out of spectroscopy but don't exactly know where to start.
All I can really go off is a high school education of physics and the various reading that one usually does when looking into something new.
The main questions are, essentially;
1. What is the best spectrometry equipment for an amateur like myself?
I have little to no knowledge on all the necessary equipment, so any recommendations would be very much appreciated. For any suggestions, if you wouldn't mind giving a reason as to why you recommend a said product, I will take this information with great appreciation.
In terms of a camera, I've read that CCD monochrome cameras are the best. How does a DSLR rank against this though?
In terms of a telescope, should I be looking at one with a specific aperture range? If so, are there any other properties I should be looking at?
Is a grating better than a prism? Why?
What software is the most effective and easiest to use?
Do I need some sort of focusing device?
2. How do you collect spectral data using the technology?
Is it as simple as pointing at a star and recording the acquired data?
How long should I view the chosen star? Is it a photo or a video?
I would assume that these questions have been asked plenty of times, so any links to other forums which discuss the same questions and topics I am raising will be very helpful as well.
Any type of reply is welcome. As an amateur, anything is helpful.
Looking forward to discussing this with you all.
