  1. Arp 315 is a small group of galaxies in Lynx located about 300 million light years from our solar system. It is quite easy to distinguish on a night of good seeing because they are of magnitude between 11 and 14, Arp's notes: Companion E (NGC 2831) is quite compact.

  2. Do you have 207 Arp galaxies photographed? It's fantastic, I'm looking forward to seeing your results, post them here, please ..
  3. Here you see the details perfectly. The 10 "are noticed. Thank you for sharing and comparing results.
  4. Good shot. The nucleus of this galaxy seems double, probably a superimposed star of our galaxy? Arp doesn't mention it. You have captured it very well, you can even appreciate a little the faint filaments to the E that appears as a challenge in this observation
  5. This nebula had always resisted me, this time the good seeing has helped me. It has made me excited to share it here. Thanks for the comment Rob
  6. This unusual planetary nebula is a very faint, rather large, irregular half-moon-shaped object, with apparent dimensions of 10.2 arc minutes. As it is so big, its surface brightness is very low, with magnitudes between +16 and +25 reported. Its NE end is brighter. Several stars are embedded in the nebula. The Medusa Nebula is estimated to be over 4 light-years across, and some 1,500 light-years away. TSoptics RC8+IRisingcam MX294 C uncooled 15x25" stack+Dark&flat sub.+ UVIR filter
  7. This is much better, I even think you have been able to capture the "object" and NGC132A mentioned in the Atlas of Peculiar Galaxies of Kanipe & Webb.
  8. Mike, nice chains of faint and distant galaxies. I love these little galaxies Outstanding shots, congratulations
  9. Your higher latitude makes it more difficult, anyway it is a good shot
  10. It Is a spiral with LSB companion on arm. Is mag 10.1, 7.5'x6.5' and SAB (rs)c tipe. The challenge observation is to see texture in the arms and assymety of the companion. In the inverted version it can be seen quite well. I have also been able to capture the "object" that Arp mentions probably an HII region. This galaxy is very low on the horizon and you can only see a few days of good seeing. Today it was. TSOptics RC 8"+ Risingcam IMX294C uncooled+ UVIR 20x15" stacked+ Dark&Flat subs.
  11. Thanks for your comments, Rob. The telescope is a Ritchie-Chretien 8 "and f8 TSoptics with a theoretical resolution, combined with the IMX294 chip, 0.58 arc. Sec per pixel. I don't use reducers and I only have a UVIR filter on. This is the original left the camera. It is a 6 mb file in .jpg as I always use.
  12. This is another object that has always been difficult for me. This year, with new equipment I have tried again and I am not disgusted with the result. It is certainly not an astrophoto but as an electronically enhanced visual observation it may be worth it. IC 2118 is an interstellar cloud of fine dust grains, about 900 light-years from Earth. It is illuminated by the nearby supergiant Rigel. Its bluish hue is caused not only by Rigel's color, but also because dust grains in the nebula reflect blue light more efficiently than they do red. The same physical process causes Earth's daytime sky to appear blue, although the scatterers in Earth's atmosphere are molecules of nitrogen and oxygen. NOTE: In the upper part there are satellite marks going through massively (at least 6 satellites) that I tried to erase with not too much luck, I'm sorry.

  13. Thanks for the feedback The Risingcam IMX224 is available at this link: https://es.aliexpress.com/item/32827634199.html?spm=a219c.12010612.8148356.20.757428c8rGXO8T
  14. I have always liked this object because of its difficulty, it is at the limit of the possibilities of my gear so I beg your pardon for the poor quality of the photograph. This planetary nebula makes for a very difficult target due to its very low surface brightness. The bubble of expanding gas is the remnants of the atmosphere of a Sun-like star expelled as its supply of fusion-able core hydrogen became depleted. Although the expanding nebula will fade away over the next few thousand years, the central white dwarf may well survive for billions of years -- to when our universe may be a very different place. JE-1 lies at RA 07h 57.8m and Dec +53deg 25arcmin. It has a quoted diameter of 400 arcsec and a visual magnitude of 12.1, a size / magnitude combination that gives it a very low surface brightness and makes it such a difficult visual target. It is thought to lie at a distance of around 1,600 light years. For star-hoppers wanting a challenge the best starting point is probably mag 3.5 omicron U.Ma from where there are plenty of mag 6 and 7 stars forming recognizable pattern leading to the planetary 8.4 degrees to the south-west. For some years after its discovery there was confusion between its position and designation with 2 small galaxies NGC 2474 and NGC 2475 which lie half a degree to the south. The matter was resolved by Ron Buta who wrote about it in the 1981 April issue of Sky & Telescope magazine.

  15. Good selection of open clusters. Thank you for sharing them
