  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. 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

  3. 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?

  4. 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

  5. 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

  6. 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?


  7. 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?

  8. My first try out at processing a color moon image (produced from a stacked image taken afocally from an AVI with a small digital camera and through my Tasco scope)

    From other images I've seen, I think the colors have come out quite well but as this is the first time I've tried this so I cant be sure. Comments welcome
