If you don't like the fanciful graphics, you can have other overlays...like a simple line drawing. I find StarWalk very good. Attachment: B13B744C-82DD-4114-9F28-2BCA2582347A.jpeg (Downloaded 16 times)

So from that it would appear that my finished image has North at the bottom... I have looked on the app store, there seem to be multiple apps called Star Walk, I have included a screenshot from my iPad I have put a red rectangle around the one I think you mean, please will you confirm, I don't mind the fee, provided it's the one you are recommending. Having read some of the blurb it sounds better than mine, which is called Night Sky. I also use Moon Plus which is a simple Moon calculator, it gives useful data rise and set times together with the exact state, waxing or waning and percentage of full.

Yes that is Star Walk ....but my version predates all these. It doesn't have a 2 or even a 1 after its name. It was also FREE back then and has no adverts....prob 2 years ago. So it looks like they have joined the 'let's put ads in the free version so people can pay to get rid of them' brigade. I would try the free Star Walk 2 version first. It it offers benefits but falls short in some way....may be upgrading to the non advert version might bring you more. The price is okay...but there's no point in buying another app if it doesn't help you enough to retire your current app.

I use Night Sky on my iPad. I think it is free. It is excellent and you can customise it to show satellites, star names, etc,

Yes, that's the one I have JK, the names and things fade away in a few seconds, before I can figure where they are they and what they say, they have gone! I will have a tinker, maybe there is a setting to fix that? I have found the pref's for 'Night Sky' I have turned off the glass figures and enlarged the text. Will try that for a while. Mind you... It seems think the Sun has risen, some hours ago???

Southern Ontario is now the overcast capital of Canada. Hard to get a clear night and the Council just spent $3,000,000 to replace all our sodium lights with diode.

Thanks Iain, I was quite surprised how much colour there is in the apparently black and white image. I think the D3 sensor has something to do with that. I am having issues with banding on the D3, I need to do some tests to work out what the envelope is. I have cut the exposure times from 30 seconds to 25 and increased the interval between exposures from every 40 seconds to every minute but some of those images I took last Sunday (12th Nov) suffered quite badly with regular horizontal banding. The star stacking software seems to remove the banding together with the aeroplane trails but I would be happier if it wasn't there in the first place. It must be causing artefacts in the finished image. Hi Mike, light pollution is an issue wherever you are, except in very isolated places or islands in the ocean. Replacing sodium lamps must be an improvement over here they are replacing piecemeal, if a lamp fails it's replaced with LED but otherwise we continue to 'enjoy' an orange cast. On my street it's about half and half! Light pollution from large cities is said to affect up to 200 miles away. In England that means you can almost never get away from it completely. North West Scotland would be the best bet from here, that means a 400 mile drive. Predictable clear skies are something of a rarity in Scotland. This is why I am so excited about the Stickle Pike location, it's reasonably high and quite dark, except for the Windscale nuclear facility up the coast which is the size of a small town. It's hidden behind hills so it's just a relatively small glow really.

You don't have to go that far Robert. Kielder Forest is one of the best Dark Sky locations in the Uk... http://www.visitkielder.com/play/discover/dark-skies?gclid=EAIaIQobChMIu6yd8vTR1wIVzzLTCh1M6wTCEAAYAiAAEgIh9fD_BwE
