I have bought a skywatcher MN190 recently as the collimation appears a little off yhink need to collminate, assumed that there would be locking and adjustment screws on the primary but theee are are only 3 assumed adjustment stews, though there are 3 screw holes for locking???
is this correct???
or should there be 3 locking Screws and 3 adjustments?
the included ‘manual’ is useless no information on this.
cant find much useful info on doing this on MN’s
assumed Colimation would be more less same as Newtonian- is that correct?

Hi everyone - Despite moonlight and some haze last night I thought I'd try a speculative shot of M13. 8" SCT on HEQ-5 Pro with Samsung Galaxy S10 in night mode, single shot, no fancy stuff. Came out quite well. I normally photograph the moon; I attach an old shot from that great period of weather back in April-June. The scope was undriven on an old alt-az mount, and the phone hand-held for that one.

I recently decided to give the SynScan app a try on my new Orion XT10g.
Now using the hand controller I was familiar with the "Brightest Star" and "Two-Star" alignments methods, indeed I always use the Two-Star method.
With the app however I see that the Two-Star has been replaced with the level north two star. What is that? And since there's no manual for the app, what precisely does level north mean? I'm guessing that you level the OTA and point north but with what precision? Any idea why that replaces the Two-Star method from the hand controller?
OK, so fine. I did the Level North alignment. I noticed that as it goes to each of the two stars and stops, while waiting for you to center the star, a couple of the directional buttons are flashing. What's interesting is that the ones flashing are not the ones for the direction that the scope needs to move to center the star. Again, what's up with this?
Finally, after aligning and doing a Goto (reasonably accurate), once it arrives at the target again, one of the directional buttons is flashing and there's a message above the object name that says that I'm to center it. Huh?
Can someone help me make sense of all this. And, is there a manual for this app ??
Hi all, as a complete beginner, who is gradually getting some kit together, the question of which Polar Alignment App I should get for my Android phone is exercising my mind. Looking at the android play store there seems to be a myriad to choose from, which do members recommend & why?
