I am new in astronomy and got my SkyWatcher Star Discovery 150Pi WiFi AZ GoTo, however I am experiencing one big problem. When I try to align my telescope using SynScan Pro app on laptop or smartphone the telescope always points wrong direction. I do not have hand controller.
I set telescope north using compass, enter latitude and longitude, but when try to align 1 star or 2 stars, telescope spins way, way off. When the star is in the South East it shows north east, or sometimes points absolutely wrong direction. When it is set on the north and object is 98 degrees east it goes some 30 degrees. It also points lower or higher.
I am totally lost.
I use 8 AA batteries.
What I do wrong?
How to fix this?

I'm just starting to get to grips with my new iOptron GEM45 EQ mount, having spent some time cutting my teeth in astro-imaging using an Nexstar Alt-Az mount. Very much an EQ virgin!
I decided to image M81 & M82 as these were inaccessible with my old Nexstar, so it was new territory for me. I used my Altair Wave 104 f/7 ED triplet scope, Photoline 0.79x reducer and Fuji X-T1 (effective FL 560mm). ISO400. 60 x 90s lights and flats. I did take 20 darks but I found that using some old bias frames from an earlier session gave a better result. Stacked in AstroArt 6, processed in StarTools v1.6.393 RC2, and polished in Lightroom. I've yet to get to grips with this latest version of ST, so for this image I haven't used the full gamut of controls. I like to get as much detail as I can from my images, I don't do subtle! Fans of a naturalistic look may not approve .
At about the 9 o'clock position there is a small blue 'smudge', enlarged here. It does unfortunately reveal some trouble with my stars!
I had originally thought that this was NGC 2976, but Astronet shows that galaxy to be too far away. Anyone any idea?
Thanks for looking.
Hi - I'm a relative newcomer to telescopes with goto - still trying to figure them out.
I have a problem with Goto on the 8SE.
Alignment usually works (Not always, but usually)
I believe my set up is correct - time and date, DST and UTC (It's currently BST in the UK)
I usually use 2-star alignment (Currently, most convenient for me are Sirius and Procyon)
Alignment usually succeeds, but goto just doesn't. The scope slews away, sometimes even to a completely different part of the sky from the selected object (I'm familiar enough with
the sky to be able to identify several bright stars without assistance)
Bizarrely, this happens even if the goto object is one of the alignment stars - how could it possibly not be able to find a star when you've explicitly told it where it is?
I've read that goto sometimes doesn't work well on battery power, so I've aquired a mains adapter. No change.
I haven't yet updated the handset firmware (I'm waiting for a serial-usb adapter.)
Any help would be appreciated.
I'm looking to get a reasonably portable astrophotography set-up, using a 60-100mm refractor, with a suitable goto mount. I spotted the Explore Scientifice exos2-gt with pmc-eight goto system, which looks like quite an elegant solution, and wondered if anybody in the forum owns this mount, and what they think of it's performance & usability?
