I have a telescope -SkyWatcher Explorer-130P SupaTrak Newtonian Reflector auto Telescope and it has a heavy duty tracking device ( pic attached). I have had this scope for a few years and did pretty much basic with this and never understood how to use this device. I have the time now to spend with the scope during this social distancing time and I am totally unaware of how to efficiently use the tracking. I know how to move up, down, left and right. I don't think it has wifi and it looks very basic ...please can someone explain how to set this up. Pleaseeeeee can someone help .......I have searched everywhere but I can't find any material on this.
Also , If i buy SynScan ( with wifi ) will it work with my scope? Thanks in advance xx
Because of the current situation, I have, as many of you guys probably have too, spend a lot more time under the stars when possible.
It has literally been over a year since last I was out doing some astrophotography because of work.
So here is my second take after the long break, NGC 3344 (The Sliced Onion Galaxy).
Initially I thought it would be a lot fainter than it was, so it was basically a shot in the dark, of just trying to get back at doing this.
But the final image actually showed a lot more detail than I would've hoped for!
Spring lent a lot of clear night, but those seems to be gone already. I would've hoped for a few more hours to add some more luminance data to it, as I did have to push it quite a bit.
I am not too happy with the shape of the stars either. Guiding was not very stable through the night, even though balance and polar alignment seemed to be good. Might need to update my Celestron PEC data?
Any advice or feedback is very welcome! 🤩

Hi,currently owned 70mm refractor, want to upgrade and many suggested me to get 6" dobsonian.
The only 6" dob i can find in my country is GSO 150mm/1200mm dob (https://www.opticaluniversescientificinstrument.com/products/gso-6-dobsonian-telescope), is this brand and specs ok?
My main targets is planet and moon, maybe some star, i wonder is it hard to imaging planets? ill be using ccd eyepiece connected to laptop.
I live in malaysia city area, very less likely i will bring the scope to darker area because its pretty far from my home,and the scope quite big, so its dobsonian suitable for minor light population?
I heard that that dobsonian can affected by weather and cooling the scope be a big issue?
hope expert can give some advice. thanks
Just wondering what peoples thoughts are on the pro's and con's of the different types of mounts out there? Do Dobsonian mounts have issues on non-flat surfaces (like a garden) or can Equatorial mounts ever have issues getting out of line too easily?
Very happy with it! Wish the sky were clear, but as we all know, when we buy astro equipment, it's cloudy! Argh!
The telescope was collected from David Lukehurst at noon and then we travelled back to Cambridge.
