  1. Thanks again everyone, much to mull over! I would like to expand my current lunar/planetary limits to some basic DSO's but I have also often thought how great it would be to be able to grab a camera on a clear night and grab some wide field shots - I guess that the DSLR route would give me greater flexibility in that regard..... what model Nikon would you suggest in a similar price range to the canon's please?
  2. Thanks all - a lot of great advice there to get me on my way. Appreciated
  3. ps - I forgot, my mount does have basic mechanical tracking that can get me around 60 secs - does that change the situation?
  4. Hi all Hoping for some assistance in choosing a first DSLR please. I'm looking at getting a star adventurer for some DSO's and also wide field (Milky way etc) and also to attach to my very basic 4.5 reflector (it does have a basic mechanical tracker than can give a good 60 secs or so fairly reliably) and I would also use it for daytime shots. Price is always key of course and my budget is £150 or so - for this on ebay I see I can get a second hand Canon 1100 or 700d etc. Which is the better camera and what should I be looking for in a purchase - eg, what is a decent shot count? Any help much appreciated
  5. Thanks Adam - I would always far prefer an honest answer and points you raised are duly noted :-) So out of curiosity, are you saying that the 290 is better than the 224? I saw some video shot with the 224 with the meteor lens that seemed to capture a wide sky view looks like I need to start saving those pennies... Any advice on best value for £ for a DSLR?
  6. Hi All Please help out an imaging newbie - Looking to purchase my first camera and I have been looking at the 2 Altair CMOS cameras I've listed (would love to stretch to their Hypercam range but budget constraints say no). I currently have a very basic 4.5" reflector (non guided/tracking) that I have been using to take A-focal planetary images (with some reasonable success) and now want to take this further with (hopefully) clearer/better images and I would also like to get some of the Orion Nebula and of wider sky views (such as the Pleiades etc). I understand the limits of my current setup and will be looking to upgrade my scope later to one that offers guidance - so the Altair scope connection seems to offer some futurebility for when I do this. I'm a bit baffled by the technical specs on the two cameras in question and note that the main difference seems to be in the different chips used. Which would you suggest is the better option please and are there any other cameras in a similar price & quality range that I should also consider? Many thanks
  7. Interestingly I downloaded an app which shows what sensors you have have installed. On my phone that does run it I have installed (among others): Accelerometer, Gyroscope, orientation sensor On the phone that does not run it (sucessfuly anyway): Accelerometer only It does run however it shows me completly the wrong hempishphere which would suggest that it does not know where it is (despite GPS). Any compass apps do not run and just show a static picture of the compass face I can only conclude that a gyroscope and/or orientation sensor are needed too for Sky Maps
  8. Actually its something I find very frustrating with the Google app store generally - no info about what is required to run a particular app. It often states what version of android is needed but a full sensors list should be included on every app page too I think
  9. Thanks that's interesting. The tablet I was looking it says it has a G-Sensor but not sure if that is enough to run the app
  10. Thanks - its somewhat confusing. The phone I know works well with sky maps has an accelerometer, Gyroscope and a magnetic sensor (among others) and it could be any or all of those but finding a tablet that has them all is nigh on impossible (at least an affordable one)
  11. Thanks for the reply, that's the problem - non of them seem to know what tablets will run it or not. I have several android phones, most DO but I have one that does not There must be certain sensors that the app uses and if I knew what they were then I could check the tablet spec for the ones needed.........
  12. Hi all Looking at buying an Android tablet and want to be able to use it with Google Sky Maps and other similar apps. Does anyone know what sensors are needed for these apps to work (ie Gravity sensor, accelerometer, magnometer etc) as I cant seem to find a definitive answer and don't want to buy something that wont work. I'm also a little confused with the different names as well - for instance, a tablet I have seen mentions it has a Gravity sensor but is this the same as an accelerometer? Thanks
  13. OK, perhaps I pushed the saturation too high. I was trying to use the Galileo images from my link as a reference point but maybe i over did it - does anyone have some good reference point images in color they can suggest?
  14. If anyone is curious how I produced this and would like a go, it was by following this very handy tutorial: http://www.colormoon.pt.to/
