  1. Cheers mate Nope its not the end yet im taking it over to M22 - which should be another two panels. Im hoping not going to have to crop too much out due to sky curvature, the raw stack for the left hand panel (#5) originally had part of M8 and the triffid on it before I had to crop them out to get the edges tidy. Im not going out again to the dark site for a few weeks, which will be fine since M8 - M22 will still be in a good position during July & Aug.
  2. Its probably best that you think carefully about this. Wouldnt it be better to have no fringing at all in the first place rather than try to bodge it out during processing? If you really have your heart set on f5 and a FL of 600-750mm then you might be better off going for a small reflector (130pds or 150pds), it will be lighter, have perfect colour correction (becuase its mirrors) and you will save a ton of cash. Plus, its a proven performer - as this thread jam-packed with images can demonstrate: On top of this, you havent told us what mount you are going to be using - which (when it comes to imaging) is more important than the telescope sitting on top of it.
  3. Speaking of Star Trek.... people who use their phones like a Star Trek communicator... gets right on my nerves! (no... I dont want to hear the entire contents of your phone call) Just a minor rant, this hot weather is making me a bit grumpy
  4. Poor marketing indeed! Perhaps they should have asked you for some images (and get some cheeky freebies in
  5. I've just taken another look at the specs.... its a bit of a lump at ~10kg... which is quite heavy. For anyone starting out in imaging, going lightweight helps an awful lot.
  6. Yes, that was taken with the Bresser 152, and is from their website: Edit: Its probably great for narrowband, but for colour imaging the blue is waaay off - which is something to be expected with an achromatic design.
  7. If its for AP, best advice is to try and find some images taken with one. If you cant find any, you have to ask yourself "why?" I'll happily tell you why, take a look at this image.... whats wrong with this picture? (actually, there are multiple issues) For AP, a bog standard 80ED would beat it stone dead. You will find that a 150mm f5 telescope which is well corrected would cost a lot more than the 550 quid asked for the 152s.... and I'm taking thousands!
  8. I'll go with "finding a dark site", nothing improves your observing (or imaging) more than a good dark place. Since finding mine, I've been getting stuff that would be quite impossible from my back garden.
  9. Yep, registar is what you need for that task
  10. Its called the Cannistra method mate but you've chosen a different selective colour balance to what I normally use (I go for blue & red). One thing you might want to try (on a Ha Lum layer) is to layer in points of interest that you may have shot at a longer focal length (ie: the pelican, wall, etc) just to crispen them up a bit - it depends on how many years worth of data you have hanging about. But add it as blend mode lighten only, you dont want to be adding resampled stars from a different telescope, its not a pretty look!
  11. Thanks Peter, I'll give it my best shot! If your location is anywhere near as dark as the one I found (and I suspect it is!) then its worth having a go at just to see if its possible. Just work quickly from right to left so youre always pointed at roughly the same altitude, plus your optics are fairly rapid so you might be in with a chance. It definitely would be nice to travel somewhere to do this properly, but probably not until the kids are a bit older. Once I have a complete set of data I will be able to look more closely at the processing, so the background levels outside of the MW are lower - which should help with sorting some of the dust out.
  12. Not outside the UK Peter it was taken at an airstrip about half an hours drive from here (between Cleobury Mortimer and Ludlow). Its a remarkably flat area of land, so I can get as much data as there is darkness at this time of year by working against the rotation of the Earth (which is where imaging at f2 comes in very handy!). Last weekend the airstrip owner had some campers on the field too, so I popped over to say hi.... which gives me an idea in that during late summer or early autumn I could take the tent out there for a mini star party I'd just need another leisure battery to ensure I have enough juice on tap for the whole night. One other thing I remember, on the way back the moonrise was stunning from there - so much so that I found it quite distracting while driving along the dark country lanes. With luck I should have it done by the end of July. I have two other windows of opportunity pencilled in for July and August, and I've already booked the time off work so all I need now is for the weather to play ball.
  13. Gotta be in it to win it mate Shooting that low doesnt come without its problems, as there was a fair gradient to deal with on each panel. There are still a couple of issues I'd like to iron out once I have the last two panels (ie: get a bit more contrast into the Antares nebula), but I think I got lucky with Saturn... I was expecting a ton of trouble from that but no flare seems present. I've taken inspiration for this project from the images Martin Campbell produces - he does some cracking galactic core shots, albeit from the South of France! But I'll mark darn sure the next project is much higher up so I can throw longer subs at it without the histo creeping right too much.
  14. Cheers Dave! I think by August, Antares is all but gone - but the main portion of the MW core should still be up, worth taking a DSLR and very short FL lens for.
  15. Cheers Sara, its just a shame the image isnt displayed slightly larger when posted. It seems to have compressed it a little.
