Hello, i am new to this forum, i made my account here because i need help.
So few weeks ago i ordered a USB to Serial cable to be able to Control my Telescope with my computer using stellarium.
It arrived today.
So i made my Star Alignment, then i plugged the cable to my Telescope and Computer, i installed the Cable driver and ASCOM Platform + ASCOM Celestron Driver.
I started DriverConnect.exe and put the Celestron Driver i downloaded, and did the properties informations ( had to tick on "Advanced Setup" and "Show All COM Ports" ) and i put "COM8" on "COM Port", then i pressed "OK" and then "Connect"
Create Creating device

"Connect to COM1 failed, no Celestron scope detected"
In Stellarium i set-up everything, the plug-in and restarted the app, then added my telescope and i says it's "connected" but i can't find my telescope.
Celestron NexStar 127SLT
The Cable i bought:
Windows 10 Pro, GTX 970, 8GB Ram(DDR4), i7 6700 3.4Ghz
Looking forward for your help, thanks in advance,
I recently got into astronomy so I bought my first telescope. I've read through several articles and the recommendation for a beginner's telescope (value/price) was Celestron Astromaster 130EQ-MD. I bought this from someone who was not really using it and it is in a very good condition. Prior to actually purchasing this, I've watched countless videos on how the telescope works, what needs to be done - latitude, RA/DEC alignment, polar alignment, etc..
After reading through all available manuals and videos, I finally brought it home from the seller (they've had it for around 5 years but it wasn't used much). After setting up the tripod, mounting the telescope and familiarising myself with all the different knobs, I pointed the mount/telescope towards north. The first thing I had to do was setting up the latitude. Since I am based in London, the latitude is around 52 degrees. Afterwards, I had to align the declination axis so the telescope can be balanced. As I understand it, you should be able to move it to any position on the axis and it should stay in that position. If the front or rear was heavier, I would either pushing or pulling the telescope after unlocking the brackets holding it together. This is where the issues began, I could balance the telescope so it doesn't move while in the horizontal position, however, when pointing it towards north, it would exclusively lean towards one direction - to the left. If the telescope was pointing to north, north-east or east, it would pull towards the west all the time. It is probably easier to show it in the video. I've spent three days trying to balance the telescope by using different methods and it just would not work.
I've also tried balancing the RA axis first. This could be somehow done, but the declination axis would still pull the telescope to the left.
It is extremely frustrating as I don't know what could be causing this. Balancing the telescope should be relatively easy from what I have heard - either push it or pull it depending on where the weight is. However, I have been really struggling to get it set-up.
I would be thankful for any suggestions and please feel free to ask any questions so I can help with finding out what is wrong.
Skywatcher 80 ED DS-Pro outfit including matched flattener and motor focus £550
This kit gives you a great introduction to astronomy and imaging, which is why it's so popular. You can see details over at FLO but there is:
80 ED Ds-Pro OTA (Objective Lens Diameter: 80mm, Telescope Focal Length: 600mm, f/7.5)
SW Eyepiece (2"): 28mm
2”/50.8mm Di-Electric Star Diagonal
Dual-Speed 11:1 2” Crayford Focuser (Backlash-Free)
Supplied with Tube Rings & Mounting Plate - please note there is a longer black vixen type dovetail fitted, not the fancy new green short one you will see on the FLO site
SW motor focus and fitting kit - I've never used this, hence it's not fitted (more details over on FLO)
Dedicated SW 0.85x reducer/flattener (see FLO for more details)
Aluminium Carrying / Shipping Case
The RRP is over £720, so grab a bargain while you can.
Collection from Nottingham, or DHL for £20 (within UK)
Hi to everyone, I used to do some astrophotography in the past with a Celestron AVX and DSLR but after few month had to give up for several reasons, including light pollution (I'm living in zone 3 east London), and also working shifts. Now I want to start again, and this time more serious. I've been searching around for a couple of months to choose all the gear and I'm quite happy with the list so far although it's a bit over the price I planned at first.
I will get an William optics Z73 with his 50mm guide scope, a flattener/reducer 0.8, light pollution filter IDAS D2 and as camera I will use a Canon 600D modded and I will buy a ZWO 183MC Pro, after so much research, I'm very happy with the scale and framing I will get with this combo, but I'm starting to get confused with the mount.
My first idea was to go for an HEQ5 Pro, as my previous experience with the AVX has been awful, then I realized that the FLO, sells that mount with belt modification and also some cleaning and tuning if required, I heard that it's a big improvement over the stock one and the price it's ok, but another important factor for me it's portability. Unfortunately, my garden doesn't allow me to do much so I will need to carry around on trolley, for a km walk, I'm a strong person and been doing plenty of time with the AVX, so my confusion came recently when the iOptron mounts entered my radar. I start comparing the heq5 pro with belt, with the iOptron cem25EC and the CEM40 without encoders, and I'm so unsure of which to buy, the cem25 seem to be the equivalent of heq5 at least speaking of payload, but in some threads I read people saying it's a bit fragile so kind of remove it from the equation although the weight it's interesting for my situation, then the cem40, seem to be quite similar on weight to the heq5 but with higher payload and that's interesting too as I will buy a C11 at some point.
Now it will all come down to the accuracy of tracking I guess, how the heq5 and cem40 would compare on tracking and guiding? If the cem40 it's better, I would probably go with that since it holds more and would last longer as I don't plan to get anything bigger than a C11, but if the skywatcher it's better, I could decide to go for that, and when I move to a place with better garden then get a second mount with higher payload.
Apologise for the long post and my english.
Can anyone identify which control box this is? Is it focusmaster? And does it run off robofocus driver in Indi lib as I cannot get a successful connection (in indi within ekos)
I bought a robofocus motor with this control box second hand.
I have faith with seller that hardware works as should.
I've tried other cables and USB ports too. The software (k stars) I use does do port search when connecting equipment..
Any help appreciated
