  1. Completed - please remove to sold section
  2. Would be the worlds biggest padded envelope if it did!
  3. I'm selling my Skywatcher 300p Flextube with full goto and dual encoders (once aligned you can use it in push to mode, then no need to realign to use gotjo again). Comes complete with an Astrozap light shroud and Telrad. I have also added a couple of dew controllers to the base of the unit and have bonded a couple of resistors to the secondary to prevent dew. The power socket has been replaced with a speakon plug/socket which clicks/locks into place - nothing worse than the power socket coming loose just after you align! The scope also comes with a base that has large lockable casters to allow for easy transportation and setup. I have a strip of glow wire round the base and a switch to save you banging into it when out observing and the scope comes with a rechargeable battery pack. Can deliver in the Edinburgh and surrounding area or further afield if you want to pay for my diesel - Price is £900
  4. M51

    This is around 5 hrs in 10 min subs on M51, I cropped it so get a bit closer in on M51 itself. Getting the background correct was the tricky bit as I wanted to keep the outer dust from the collision, did a wee bit of sharpening on the galaxy core as well. Imaged with QHY8 and Altair 8" F4 Newt
  5. I have extracted and sharpened, deconvolved an M51 image Im working on but for the life of me I cant see the LRGB combination tool in Pixinsight! When I open Chanel Combination it only shows RGB, what am I missing?
  6. M44 Beehive Cluster

    It was 3 min subs X 9 if I remember - the camera is a QHY8 OSC so no ISO etc
  7. But how did you calculate this?
  8. I found this page - https://spacedoutclassroom.com/2016/01/04/the-distance-modulus-method/ Which works out the distance to Fomalhaut by getting the antilog (this is all new to me BTW) of the distance modulus (I think) which is 1.72 for this star. However the galaxy Im interested in has a distance modulus of 45.41, getting the antilog of this gives me this - 2.5703957828e+45 parsec which seems wrong. The previous page said there is 3.26 Lightyears per parsec, so multiplying the previous figure by that gives me 8.37+45 Lightyears, I assume I have done something wrong?
  9. Thank for the link, I looked up this on: http://leda.univ-lyon1.fr/ledacat.cgi?o=pgc2819573 It has this but Im not sure how to calculate distance in Light Years from this? - Cosmological distance modulus (from vvir with ΛCDM) - 45.41
  10. I imaged M44 last night and there are loads of little PGC galaxies in it, if I google them there is no info available, I really want to know, just for my own interest, how far away they are.....
  11. I just checked one of my subs an there is no start where your wandering one was - I suspect its a reflection that is somehow following your guiding corrrections
  12. It’s cheaper to buy 6mm wide pulleys and belt, can get them delivered 1st class for £8
