  1. Thanks for the kind comments. The seeing last week was exceptional, I typically find the best seeing in Autumn months on those dewy nights after midnight. It did cross my mind whether the recent reduction in air pollution may be playing a part, but its seems a bit fancyfull! Adrian
  2. Still processing images from the excellent spell of good weather a couple of weeks ago. The nights of the 22nd to 24th April gave the best seeing of the week, so was pleased to image a nicely detailed galaxy. Around 9 hours of data, 6 hours luminance, no Ha Taken with an ASI183MM and SW Esprit 150 Adrian
  3. Photoshop is so powerful these days, that almost any colour balance can be achieved. The astro imager, aka artist, can portray whatever he/she wishes. I do think that audiences are more wowed by high colour saturation driving this type of processing.
  4. Shibby, Thanks and I agree about the colours
  5. George, 1.7 arc sec, so not bad
  6. Thank you Bryan, Carole, Mark and Sam for kind comments! Adrian
  7. Many moons ago (around 20), I lived in Dulwich, so can sympathise with you. You best bet is to concentrate on narrowband imaging of nebulae, of which there are many many targets. There are some bright objects like open star clusters and globular clusters that are worthwile imaging. Then secondly, if you can, take you kit out of London to a much darker sky and image broadband objects. As long as you are enjoying your hobby, then it doesnt matter how much light pollution you have and I think you have done very well with the above image from near central London. Adrian
  8. This faint galaxy group high in Ursa Major is a struggle from a semi-rural site, i.e. my back garden, I totalled around 15 hours of data. Other astrophotographs show a predominantly blue galaxy except for the center, but using Astrodon true colour filters and APP's calibrate star colours, my version shows very little blue. C'est la vie! Taken with a SW Esprit 150mm and ASI 183 camera. With a pixel scale of 0.47 arc sec/pixel, high resolution imaging is possible with relatively small scopes. I do think this galaxy group is very attractive and infrequently photographed, so pleased to get something a bit dfferent.
  9. Hi Francki, I'm please the good seeing extended to Southern France Makes the lockdown more bareable... This image was taken over the nights 14th/15th April and I have a couple more images from last week where seeing was even better. Adrian
  10. Another one from our lockdown period. Around 8 hours of data taken over a couple of nights. I used an Esprit 150 and ASI 183 on top of a 10 micron mount. Seeing was very good and fair transparency. Adrian
  11. I managed to see the full resolution version here
  12. Excellent image, defintely need to see the full res image to see its full glory Adrian
  13. Wonderful run of clear skies here in the East of the UK, what a week we could have had at Kelling Heath! Here is one I have now completed processing. Taken with an SW Esprit 150 and ASI 183 camera. Around 6 hours of total integration time. Edit - Just tweaked the colour balance, after a review the next day! Adrian
  14. I'm guessing there will be a flood of images with clear skies galore and lockdown. Here is my first of the lockdown period, NGC4565 taken with a 12 inch ONTC and ASI1600MM camera. A total of around 8 hours data. The sharp eyed among you will notice the odd spider vane spikes, a result of rotated images during a couple of sesions to get the data.
