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 recently scored a great deal on facebook marketplace and bought Skywatcher Skymax 180 mm Maksutov-Cassegrain Telescope (f/15) with EQ6R-pro mount. I understand that long focal length telescopes are more suitable for planetary imaging. However, as I am tight on budget, I would like to use the same scope for deep-sky astrophotography. I have Canon Rebel T5 DSLR camera that I am using for taking images. Without autoguiding and a decent polar alignment, I can get ~30 seconds long shots without any star trailing, but that's not sufficient for imaging objects like M51. I would like to be able to integrate longer, say few minutes, thus would like to purchase an autoguider. Here are some specific questions I have.
1). The telescope comes with an 8 x 50 straight-through finder. If I were to use it as a guidescope, what type of image integration time can I expect? Has anyone done autoguiding for f/15 scope with an 8x50 or other finderscopes?
2). If the integration time will be an issue with the 8x50 finder scope, I am open to purchasing an off-axis-guider. However, considering the narrow field-of-view of Mak-180 telescope, I am concerned about not having enough photons from guidestar for autoguiding. For instance, with my DSLR camera, I need to integrate 20-30 seconds to see the nearby stars in M51. What type of OAG and camera would I need to autoguide with my scope? Are there affordable cameras (~$200) that would do the job for me? Would ASI120MM Mini Monochrome (~$150) do the job? What about OAG?
I plan to use phd2 software for autoguiding rather than relying on the build-in guide port on the mount. Instead of integrating for hours, I am planning to do DSS stacking of few mintues long multiple shots, hopefully this will put less strict requirements on the autoguider.
In case this information is relevant: with my current setup, I have no issue pointing my scope to a desired deep-sky object, track the object within the field-of-view of my DSLR camera for hours using the mechnical tracking of the EQ6 mount. For instance following is a single raw image of Ring nebula taken with 30 seconds shot. But it is not enough for generating high-quality images.
Thank you in advance for your help.
