  1. The IMX294 C chip is very sensitive and for this type of weak objects it works well. Thanks for the feedback Mike......I think I see UGC 957 in your photo !
  2. ARP 157, NGC 520 and companion. Disturbed with interior absoption Challenge: Faint tails N and S and companion UGC 957 RC 203 + Risingcam IMX294 no cooled+ UVIR 15x25" stacked with Risingcam software+ Startools
  3. Ritchey-Chretien 203 mm+ Risingcam IMX294 no cooled+ UVIR filter 15x 25 " , Risingtech capture soft, gain máx. all parameters by default Processed with Startools
  4. Fantastic shots. How lucky to see the southern hemisphere sky. You will have some good memories of the trip to your home
  5. NGC 5614 is a spiral galaxy in the constellation Bootes. It is the primary member of the Arp 178 triplet of interacting galaxies with NGC 5613 and NGC 5615 TSO RC 8" + Risingcam IMX294+ Risingsky software 10x25" + DFC+ Startools
  6. I chose the EEVA because I like simple things, so I use alignment to a one star close to the object I'm going to visit and center this allign star with a 50/205 mm finder + an illuminated eyepiece of 26 mm. I also do not like the 6-bolt fastening system because the finder moves too easily. I've tried and rejected all laser finders because the red dot shines too much for most alignment stars
  7. Actually these galaxies are very interesting. But at the moment I continue with my particular marathon of objects of equal or less than 12 magnitude and until I finish it I can not start a new one. If the Mediterranean sky behaves moderately well I hope to finish it this year. Between all we are going to obtain a quite complete collection of celestial objects...
  8. IC 983+IC982/ARP 117 is a 11th magnitude Spiral Galaxy appearing in the constellation Bootes. It is 267 million light years from our solar system NGC 5490C /ARP 79 is a 15th magnitude Spiral Galaxy appearing in the constellation Bootes. It is 277 million light years from our solar system. TSO RC 8" + Risingcam IMX294+ Risingsky software 10x25" + DFC+ Startools
  9. NGC 4775 is a 11th magnitude Spiral Galaxy appearing in the constellation Virgo. It is 77 million light years from our solar system. NGC 4786 is a 11th magnitude Elliptical Galaxy appearing in the constellation Virgo. It is 216 million light years from our solar system. PGC 43771 is a 15th magnitude Galaxy appearing in the constellation Virgo. It is 323 million light years from our solar system. PGC 1030299 is a 16th magnitude Galaxy appearing in the constellation Virgo. It is 219 million light years from our solar system. TSO RC 8" + Risingcam IMX294+ Risingsky software 10x20" + DFC+ Startools
  10. Well, the hobby erases borders. I have learned a lot, almost everything I know, in an American forum. At least we behave like inhabitants of planet earth, without borders or languages (thanks GOOGLE!)
  11. This subject is quite hidden and with very low participation, maybe if it were taken to the section of EEVA would have greater participation?
  12. The latest versions of Risingsky have the option of taking and applying the so-called "flats". Actually I do not use them for EEVA because any subsequent treatment with Startools, Pixinsight or similar perfectly corrects the defect. The IMX224 has been and continues to be, in my opinion, one of the best and cheapest chips for EEVA, it is very sensitive and combined in an appropriate way with a telescope like the SKW Quattro 8 " it gives a magnificent result in small and weak objects like galaxies , planetary nebulae and globular clusters In the link of my signature you can consult the Telescopius some of the results. Effectively FOV is the main parameter in EEVA if we want to have the maximum detail . The idea is that the main object occupies most of the FOV and this forces several camera / telescope combinations. The size of the IMX224 makes it impossible ( or very difficult) to use it in medium or large objects, so for these cases I use the IMX294 without refrigerating of Risingtech combined with a TSoptics RC 6 "or a TSoptics APO of 3". I am waiting for the first bright nebulae to appear in the East to be able to make the first tests!. Previously I used ATIK Infinityvand even the Panasonic P / MN34230 (ASI1600) but the Infinity had problems with the color balance and the ASI1600 little sensitivity for EEVA. The IMX 178 is a good chip but it does not work well for EEVA, it is not very sensitive and you have to increase the exposures that you will need work guided to have acceptable results and that is already Astrophotography not EEVA.....IMHO
  13. Thanks for the comment Risingcam cameras use their own software that allows you to take and apply the so-called Dark Frames or Dark fields. DFC stands for Dark field Correction.
  14. OK, thanks. Is the IMX290 chip. A good choice for EEVA. Have you tried the native software of this camera, the Risigsky software? To me it seems very complete and easy to use
  15. This is an interesting observation about this galaxy published in the Astrophysical Journal v.451, p.156: "A remarkable structure in the innermost regions, composed of four main unresolved sources symmetrically distributed around the center, is apparent in all R, I, and Hα images". The image, taken with amateur media and with the EEVA system allows us to distinguish some of the details that the authors mention in their report quite well. The color also helps a lot.
