Yes. Have you got one of the supporting apps?

Polaris is not actually dead centre on the celestial pole. Even viewed through the low magnification of the alignment scope, it will trace a small circle. To be correctly aligned, polaris needs to be on the right part of that circular gauge at the right time. If you don’t turn it on then it will have drifted by the time you use it.

However it will drift a bit anyway unless your mount is perfectly level and perfectly aligned, so it might be better to get polaris aligned and leave the mount turned off, then perform a final adjustment just before you start your imaging.

I know I found when I was out last, it would have been worth having the mount assembled, the camera in the right shooting mode etc ready to nip out late on. It took so long to set up, it was getting late before I started imaging.
Yeah, I’ve got SAM Console so that gives the position as to where Polaris should be in the reticle.

do you do your alignment once you’ve got your camera on the tracker or beforehand? When I tried it on my old weaker tripod the alignment drifted so far out it was a pointless exercise. Set my new tripod up last night and it feels so much more solid so hopefully I’ll have more luck.

I've struggled to do the alignment with the camera on but you need to make sure you don't knock the alignment out when putting the camera on.

I had been using the long dovetail bar which does have a hole through where you can do the alignment, but when I had it out last I discovered the short round mount which will allow my camera to sit in the middle. You can't align through that.

I’m going to give it a go without the fine Tune dovetail bar, think that should be ok for the DSLR and 35mm lens, be interesting to see what it’s like with the 600mm lens on it, might have to use the fine tuning bar for that
 
I took this photo almost 2 years ago. Nikon D700 with a 14-24mm lens at
2nd attempt.

I took this photo almost 2 years ago at a place called Cape Schanck. Nikon D700 with a 14-24mm lens at 14mm over 30s exposure with a tripod and delay. I cheated a little in Lightroom afterwards and dropped the skies a little to make the colours pop a little more and please do not look too hard as you will see some softness in the stars.

The dark area in the bottom right is Pulpit Rock and the bright spot of light just to the left I think is Venus.

That is amazing for just a 30 second exposure!

I did make the sky darker in Lightroom to make it pop more, but yeah, 30s did it in near total darkness.

(also I did take very very many photos before I got one I liked. It is not like I just arrived, set up, took one photo and left again)
