  1. Last time was the first usable, fairly clear night since my return from my business trip. I had the telescope out imaging 2x planetary DSO (M57 & NGC7662) and left everything running into the night waiting for Jupiter to clear my next door neighbours house. Everything was ready, the DMK21, IR_filter and my new, well second hand Celestron 2x Ultima barlow. I was a little worried about this test, since in the past I have been using my ExtQ 1.6x with the Mewlon which is of course a very high quality piece of kit from Takahashi. So what could I expect from a Celestron Ultima 2x barlow??? I'm very very impressed by the results so far, see for yourself! The image scale has benefited greatly, the brightness has decreased and I'm now at my camera's maximum sensitivity. Also, I have increased the frame capture to 5000 from 2000 previously. Transparency was average to poor but the seeing was excellent all night. I managed to get 3x runs in before the image faded away as the clouds rolled in. I'm very happy with the result and see it as another step forward in my planetary imaging. Right now I probably don't have the optimum setting that will change with more time and experience with this setup. I more sensitive camera maybe needed, perhaps for Christmas!!! I still can't quite believe the quality of this rather small compact barlow package, its excellent and I must thank "Neil Phillips" for the recommendation. My WO Barlow was sold long ago and despite its size 2" and 3xED optic element claims couldn't compete with this package from Celestron. I have never used a Televue barlow or powermate but if I were them I'd be buying these Celestron Ultima up and crushing them, since from a Price v Performance point of view I cannot see a Televue barlow / powermate being that much better, its just not possible!!!
  2. Very nice captures... Just out of interest, how many frames do you capture per colour?
  3. The next question is what altitude are you at??? I guess not too high, can't remember any mountains in Essex? Still living in Holland anything above 3m is a decent size hill!!!
  4. I personally prefer the electric blue version of this object but its very difficult to process correctly...
  5. That what I appreciate, its the only way to improve, right... Now I'm just worried my Laptops going to have a heart attack... 2000 frames = 600MB so 7000 must be getting on for 2.5GB??? How much data would you capture in a night? Because at that rate I'm going to need an external harddrive!!! (Sorry - yes it was with the 1.5x drizzle turn on)
  6. Been having a play with AS2! (AutoStakkert2) this afternoon and have produced the above image. It's good, but I think its a little softer than the images that have been processed the normal way with Registax 6. Still, perhaps I'm not adjusting the right parameters yet! I'm interested to know what stack sizes you are all working with? I'm collecting 2000 frames for processing which is approx. 600MB. The detail is increasing but so is the noise! So when the 2.2x Celestron barlow goes in I'm worried that the noise will become too much?
  7. Fantastic set of image, just excellent!
  8. Hi Andrew, Everything is greyscale at the moment since I don't have the colour filters for planetary imaging, I will look for some secondhand in due course...
  9. Excellent capture and result, I got up a little earlier that you!!!
  10. Very nice capture and colour detail coming though...
  11. Well I had a fairly productive night under the stars despite the almost full moon! Started out learning some new techniques for my DSO imaging, drift alignment with Metaguide etc... and gathering data on M57 until the unscheduled clouds rolled in for a laughs!!! Went to bed and set the alarm for 03:00 this morning when Jupiter would be in position for an image run... Got straight into it with the ExtQ, then I decided to try to see if I could increase the amplification of the ExtQ by adding a short extension tube and guess what it worked... This morning I calculate that I had about 1.9x instead of the 1.6 times magnification and you can clearly see the diference in the image set attached below. All image runs were 2000 frame @ 30 frame / sec using Firecapture and the DMK21 USB camera. Also, I now have a Celestron Ultima 2x barlow on its way to me from the UK, so when I return from my business trip, weather gods permitting I can push the Mewlon harder. I hope yo like the set, everything has been processed in the normal manner. However, I'm going to have a play with A2!S this afternoon to see if I can make any improvement. Your tips / suggestions are welcome? PS it great imaging the planets, I can post the result the next day, with DSO I have to wait sometimes a month to complete the image!!!
  12. That's it perfection! The dust lanes now are giving it that extra dimension! Looks like a warped record but much more beautiful.
  13. One minor comment would be that it does look a little flat, with 45 hours of data and a little "Local Histogram Equalisation" would give it more of a 3D effect, a bit of depth? I know that you need to be careful with this tool but I'm sure that you can manage to apply it.
  14. Now its getting boring!!! Fantastic image though.
  15. Too simple a conclusion; 1. Newton's (reflectors can be used for DSO and planetary) normally anything with a focal ration of F6 or higher is for planetary and F5 and lower DSO's. 2. Cassegrains, schmidt or otherwise are for planetary and the smaller DSO's but with a suitable reducer they can be fairly multi-purpose (never wide field though!!!) 3. Refractors cover everything from wide-field to planetary but a good place to start is in the range of 500mm to 1000mm; again used with reducers or barlows they can do almost everything! The most important point for you is that a good refractor doesn't need to be collimated and will delivery a good illuminated field for a DSLR camera. Most of the stuff out there to be imaged is Huge / enormous!!! 100 / 1000 or light years across! You will need a couple of years before you will be ready to work your way up to the long focal length telescopes and trust me they are a real pain to work with at times... You need exceptional weather conditions to get the most from them, fact.

  17. Looks very nice, so now add some colour!!!
  18. Very nice capture, if you find something on Winjupos I'm interested too!!!
