  3. olympus omd em5 with 0lympus 12-60 zoom set5 at 12mm, 5 sec exp, iso 1600.  f2.8. manual focus the sensor is a 2x crop. if you haven;t booked your  northern lights tour yet just take the cheapest  as they all go to the same place. This was the advice given  by our  independant reykjavic  city tour guide and indeed so it turned out. when we got there plenty of other companies were there and more turned up

  4. I agree it is the more logical move and when I get the chance I do put links through but it comes down to some people would rather use facebook than a forum. These people are primarily photographers who wish to photograph space rather than astronomers who wish to image what they have seen. Some people are starting to realise they will need some knowledge of astronomy but most just want to take photo's and would feel daunted coming to an astronomy forum to ask for advice.

  5. First of all if this is a breach of the rules my apologies and if mods decide that this is so I understand.

    I recently joined a facebook page on photography as I am learning how to do it and people have been very helpful. It has however become so big that it has had to split into various sub divisions one of which is astrophotography. The problem here is that although there are a lot of people interested in the subject there are no experienced imagers. Is there anybody interested in helping a bunch of rank beginners to  do some imaging. You will need the patience of job as most don't even know what a t-ring is they have no idea what equipment is used or why. I see it as a sort of outreach thing I don't need many just a couple of people who know what they are doing and can spend a few minutes a week to encourage a bunch of newbies who have no idea but would like to learn a little. pm me  if interested.

    here is a link to the camera i had in mind, it looks like the front might unscrew/rip of to allow a 12mm threaded nosepiece to go on.

    sounds like some one has to spend £30 to find out

    That does look interesting I need to figure out a way of focussing that doesn't involve me using a soldering iron or having to reprogram. thankyou it does open up avenues of investigation

  7. This is not my first stupid Question and I have no doubt it will not be my last but could a GoPro be used for planetary imaging? I am trying to think of ways to do planetary imaging without a laptop or is there a webcam that could be hooked up to a small tablet? I am pretty much at my limit with what I can carry.

  8. Thanks guys. Just had a look at the website. The guy seems to know what he's about which is good to know.

    What about Astronomiser? Does anyone know anything about them?

    They are also very good and highly recpommended

  9. its a cost benefit thing fast  scopes are what you need for imaging  an 80mm is relatively cheap to get a reasonable focal ratio a 100mm costs an awful lot more. take the ed80 at 7.5 its a relatively slow scope add the focal reducer and you get 6.35 which makes it just within the realms of easily usable for imaging. If you take the 100 ed at f9 and add the reducer you get f7.65  which is still a slow scope for imaging this means you need  longer exposures maybe a better (more expensive mount) take a look at the esprit one of the cheaper good 100mm scopes optimised for imaging you are talking about  £1400 Nb people are recommended the ed 80 not because its the best but because its the easiest cheapest scope to  use. the usual question we get is "whats the cheapest easiest scope to start imaging with?"

    the cheapest imaging scope is now the 130 pds although some would argue that the ed80 is easier
