alignment on a small part of the sky
« on: 23:38:21, 24 June, 2018 »
I’ve moved to a location where by I can only see a small part of the south facing sky ,
So I cannot see the polestar, to be honest I cant see much at all except one or two planets and the moon, my question is because I cannot get a polar alignment, how can I get the mount to stay fixed on a planet or the moon, so I can at lest use a webcam to grab some data my mount is a CGEM-DX many thanks Dave
sorry i think i have posted this in the wrong section

I have something like that in my balcony.
With planets staying enough for imaging the requirements are minimal.
You only need to use your location information for latitude (between 0-90 North) and you can use compass for longitude (East-West).
For more accuracy you can use drift alignment but for planets it's not needed.

Did a short google search for 'polar alignment without polaris' and quick look at finds and this looked like it could be useful.

S - he says cgem dx.

With a focal length of 2800mm for the C11 you're going to need to be fairly well aligned.  As Tapio has done, just Google for "daytime polar aligning" and you'll find lots a YouTube videos showing various ways to do it.

You may also want to consider getting a Polemaster (https://www.modernastronomy.com/product-category/polemaster/) which will take all the pain out of it !
