  1. I descend to my other observation and study the pint nebula and packet of crisps cluster ;-)
  2. All the streetlights in Hartlepool where I live were replaced to LED a while ago now and has made a VAST difference to the quality of the night sky...I can now see the milky way from the back garden :-)
  3. The double stars are produced in photoshop with a Wacon 4 tablet.
  4. Hi guys Just finished a website so if you can then check it out http://deep-sky-adventures.weebly.com/index.html Love to hear feedback. Cheers Darren
  5. Its a 2 inch square black box of tricks that you attach to the focuser just like a webcam but it at its higher settings will capture 256 frames then stack them then display the image onto the monitor. It takes about 10 seconds to do this then its a continuous video stream but it gives you between 2-3 x the aperture of your scope so my 10 inch reflector essentially becomes minimum a 20 inch aperture. It also features an unlimited manual mode whereby exposures are controlled by a start/stop button, and a lunar/planetary mode with fast shutter speeds down to 1/2000 sec. i have seen 18th magnitude stars with my 10 inch using the Watec which is not too bad...at least I'm not complaining ;-) Darren
  6. I actually use a skywatcher 10 inch F4.5 Newtonian with a watec 120N+ astro cam as my sky conditions are not so good. Darren
  7. Well, it was actually a really excellent night on the night of the 17th and as I have sorted out the eq-ascom problems thought I would test the system out just to be sure! M76 the little dumbbell: This was an excellent sight as a lot of detail was seen plus a nice bit of the outer nebulous envelope. M77: Only small but tight spiral structure was seen and a curious brighter patch just south of the core, perhaps a very faint star of just a brighter HII region? NGC1514 the Crystal ball nebula: I thought this would have been easier but it was quite diffuse but there was some internal structure plus a nice bright central star. NGC 7635 the bubble nebula: the observation of the night and more seen than I thought. The bubble itself was bright but diffuse but there was a much brighter, defined strand that stood out plus a very bright triangular area just below the bubble. other fainter patches of nebulosity was seen around the field of view.
  8. Can anyone tell me how may wires are soldered to the derial D part of a bought eqdir module as mine has been acting strange lately and it lost the connection to the scope saying the usb could no be recognized but trying it on two different computers with the same results I assume it is the dongle. Taking it apart I notice there is a blue, a green and a white with blue stripe wires with a bunch of other wires so I was wondering if a wire has come away or perhaps the dongle has just failed. Any advice would be greatly appreciated. Darren
  9. I have always used the pilot pens and they have always been perfect.
  10. I always use a 0.1mm technical drawing pen for stars, you can get pretty much perfect dots to minute discs for the brighter stars.
  11. This galaxy must be coming towards us because its clearly blue shifted!
  12. Well, just spent 10 minutes doing a long write up for these and something has happend and now I dont have the text anymore:mad: so I'm just posting the sketches with out the write up. As usual done with the 10 inch F4.7 Newt and Watec.
  13. The globular NGC 2149 is a real pain, easy to see with the watec but to resolve:eek: but considering its about 300,000 light years distant I can forgive it
  14. Yep, I would say at full integration my 10 inch is at least a 22 inch probably more in good conditions.
  15. I do tweak the controls constantly bringing out different levels of detail, low frame rate to bring out very bright areas lke the central part of M42 then going a full 256 frames for the fainter stuff then you have to constantly mess around with the gain and possibly the gamma, worth it though
  16. No I would consider that cheating, I actually sit in a tent by the computer and sketch live off the screen constantly tweaking the controls on the Watec handset to bring as much detail as I can.
  17. What a night, set the 10 inch and Watec up and really enjoyed myself, M1 The Crab nebula was extremely detailed and took about an hour to sketch. M82 was just amazing, never seen that amount of detail in it before. NGC2419 the intergalactic wanderer had a bit of resolution but mostly looked like black pepper sprinkled upon black velvet and I dont think I'll get any better than what I saw last night. NGC 2261 Hubbles variable nebula had more detail than I thought would be there but very pleased at the view. M78 showed a fair amount of detail but was been spoilt by light pollution. I was out for about 5 hours in total. Darren
  18. I used my watec 120N+ a few months ago on Uranus and saw 3 moons easily through my 10 inch F4.7 Newtonian. Should have really put a barlow in for a larger scale though.
  19. I have seen it and looks well worth having, shows you everything you need to know.
  20. That M33 sketch is pretty good, you have captured what it does indeed look like in a 12 inch, you should be very proud. One thing try and get hold of an artists stump, simply a very tightly would bit of paper like a pencil to blend with as you can get superb looking nebulae using one, I use then all the time.
  21. Yes, it was the observation of the night, I was AMAZED what M33 looked like on the monitor, I diddnt expect to see that much detail then you think..How the hell am I going to draw it! bit as an professional artist it wasnt that difficult. Mind you It's not just simply looking at the monitor and drawing, you are constantly adjusting settings on the watec control pad, the gain, the gamma trying to bring out every bit of detail you can...bit of a hassle really but the end results are always worth it
  22. I use a Watec 120N+ camera with my 10 inch so it is really giving me an aperture af i would say about 22-25 inches aperture, it's the way the watecs work... fantastic
  23. The Watec is an astro video cam, you attach it to the eyepiece of the telescope and use the video feed on a monitor to observe. The good thing about the watec's are they have an interigation mode whereby it will record up to 256 frames then combine them then it displays the result on the monitor, it takes about 8 seconds to do this then it simpky repeats it giving you a continous 'live' video feed but because all the frames are stacked it gives you a much more detealed image appearing to double (or more) the size of your scope, this is why I can see stars down to magnitude 17.5 with a 10 inch reflector. I then draw what I see from the computer screen so in essence they are sketches. The only post processing I do is to invert the drawings in photoshop as I actually sketch them with pencil onto white paper.
  24. The OIII is the worst filter you could use on the Horsehead as to see the horsehead you need to see IC434, the faint strip of emission nebulae it is superimposed on. Trouble is it IC 434 doesn't have any OIII emissions, it emits hydrogen beta so you would need either a H/Beta filter which at only 9nm bandwidth will probably rob too much light or the UHC which does transmit this weak h/beta line.
  25. M42 looks better if using a UHC filter.
