  1. First thank you very much for the compliment. I will keep posting my images in this great Forum with no doubts. Regards, Fernando Hi Olly, Thank you so much for the gentle comments and appreciation. Regards, Fernando Hi Rodd, Thanks alot for your comments and kind words. With the C-11 this galaxy should be great. I am eager to see your outcome. Regards
  2. Thank you very much for the kind feedback. I am happy that you like the image Regards, Fernando Thank you for the great evaluation. Regards, Fernando Thanks alot for the kindness! Regards, Fernando Bobby-dazzler is your more than kind and generous comment, to wich I am very grateful. Indeed, it made my day! This image has been taken from my home observatory in a week with the seeing particularly very good. Also the matching between the camera SX-694 and the Skywatcher Quattro, a Newt 10" f/4, played an important role. Once again, thank you very much. Regards, Fernando Thank you so much sir. I appreciate your thumbs up. Regards, Fernando
  3. NGC 1097 is a barred spiral galaxy and also a Seyfert galaxy. The galaxy is 45 million light years away from us in the constellation Fornax. It is a severely interacting galaxy with obvious tidal debris and distortions caused by interaction with the companion galaxy NGC 1097A, visible on the image aligned with the major axis of the elliptical shape of NGC 1097's core. NGC 1097 has a supermassive black hole at its center, with around 140 million times the mass of the Sun. Around the central black hole is a glowing ring of star-forming regions with a network of gas and dust that spirals from the ring to the black hole. An inflow of material toward the central bar of the galaxy causes new stars to be created in the ring. The ring is approximately 5,000 light years in diameter, the spiral arms of the galaxy extend tens of thousands of light-years beyond the ring. The ring can be seen on this image, well in the center of the core.

  4. Thank you for the very kind evaluation. Regards, Fernando Thanks for your comment and appreciation. Regards, Fernando Thank you very much. Best Regards, Fernando
  5. Hello my friend, Thank you very much for the evaluation, Regards, Fernando
  6. Thanks for the appreciation Ian !! Best Regards, Fernando Thank you so much !! Best Regards, Fernando Thank you ! Best Regards, Fernando Thank you, your comments have been highly appreciated. Best Regards, Fernando
  7. Thanks Dave, but your last image is great, there is nothing poor in it. Best Regards, Fernando Thank you so much ! To be true, neither do I. All we have here is rain, lots of rain. Best Regards, Fernando
  8. Really nice full disk Dave. I can see some filaments almost on the center. These filaments were not there on Sunday, when was the last time I observed the Sun. Best Regards, Fernando
  9. All the advices above are very nice. I would inlcude the following: A field flattener (without reducer just the flattener) http://www.telescope.com/Astrophotography/Focal-Reducers-and-Field-Flatteners/Orion-Field-Flattener-for-Short-Refractors/c/4/sc/64/p/99608.uts A LP filter. Hutech carries the one I think is the best http://www.sciencecenter.net/hutech/idas/lps.htm Regards, Fernando
  10. This is the first image of The Sun that I managed to do this year. The Sun was very calm, with small and dim prominences and without features in the chromosphere, unless small archs and filaments on the northern limb, causing very little activity. Setup: Scope: Esprit 120mm f/7 Filtro Ha: Daystar ION 0.5A Camera: PGR Grasshopper Express bin 2x2 Thanks for looking, Fernando
  11. Wow, you did a great job !! You have reduced the background to a constant value of 40 counts over the whole image. Great ! Keep up the great job. Fernando
  12. Distant from Earth 11 736 light years in the southern constellation of Carina, NGC 3199 is classed as a diffuse nebula, embedded with a highly assymetric Wolf-Rayet star close to the center of the ring. The nebula is about 75 light-years across. A Wolf-Rayet star is hot, short-lived and generates an intense stellar wind. The one in NGC 3199, as mentioned, has a highly asymmetric morphology, with a very bright hemisphere near the exciting star HD 89358 and a much fainter and more extended other hemisphere. This nebula is modeled in terms of the distorted bubble produced by a moving star blowing a strong stellar wind into a surrounding uniform interstellar medium. This description is an outine of the article found in: http://articles.adsabs.harvard.edu/cgi-bin/nph-iarticle_query?1989A%26A...226..270D&defaultprint=YES&filetype=.pdf The image is a LRGB standard enhanced by narrow band data from captures of 12 subframes of 20 minutes for each channel (Ha, O3 e S2).

  13. Hi Tom, For Photoshop, there is a plugin from Russel Croman called GradientXTerminator. You can find it here: http://www.rc-astro.com/resources/GradientXTerminator/purchase.php Version for 32 and 64Bits PS are available. In my opinion, this is the best plugin to reduce the astronomical images gradient. A manual nice approach that doesn't imply to buy the plugin, can be found here: http://www.flemingastrophotography.com/gradients.html Regards, Fernando
  14. Hello my friend, I thank you very much for the kindness in evaluating this image. Best Regards, Fernando
