  1. Leo Triplet (M65, M66, and NGC 3628), The Leo Triplet is a small group of galaxies about 35 million light-years away in the constellation Leo. large version at astrobin https://www.astrobin.com/391520/ Date: 4th January and 2nd February 2019 Mount: Skywatcher EQ6-R Pro Telescope: Orion 10" f/3.9 Newtonian Astrograph Camera: Nikon D5300 self modded full spectrum Total exposure: ~3 hours Subs : 300sx36, Flats, Bias, Darks ISO: 400 Guide Scope: Orion 50mm Guide Cam: ASI120MM Filter: Optolong UV/IR cut Corrector: Baader MPCC Mark III Coma Corrector Capturing

  4. please check here. you will need all the details for them. http://www.astronomyforum.net/astrophotography-forum/197165-few-stuff-taken-my-kit-lens.html http://www.astronomyforum.net/astrophotography-forum/197850-m8-m20-sigma-50-500mm-lens.html http://www.astronomyforum.net/astrophotography-forum/156345-eta-carina-nebula-ngc3372-widefield.html
  5. thanks. no its not. all images are less than 1 hour of data. between 5min and 45min. subs are between 8sec and 30sec. i can search my data and give exact details if you want.
  6. all of these except for the last one taken with a nexstar GT mount bought from ebay for 70$. most of these are few years old. now i have a good setup but this is how i started and fell in love with this hobby. 55-300mm lens + D5100, eta carinae 55-300mm lens + D5100, lagoon+trifid 50-500mm tamron + D5100, lagoon 50-500mm tamron + D5100, omega centauri 6" newtonian + D5100, orion 55-300mm + D5100, rosette 55-300mm + D5100 50-500mm + D5100, trifid 55-300mm + D5100, orion tripod, D5300, 50
  7. also double clusters or Pleiades but don't expect nebulasity in short exposes.
  8. Andromeda should be an easy bright target in the west if you want to try before 10pm
  9. if the wind is a big issue, you should consider a refractor than large Newtonian/RC or SCT tubes. they all will act like a sail in the wind.
  10. these mounts are in entrirly different class than star adventurer mounts. you will not loose any subs due to tracking errors if you are guiding and there is no much wind. i took the above with occasional wind so the subs are limited to 5min. i had to remove 2 subs out of 38 due to strong wind bloating the stars. thanks.
  11. Looks like Skywatcher 250/1200 OTA is around 14.5kg, I'm using an Orion 10" F3.9 Newtonian Astrograph + EQ6-R pro without any issue. its an 18kg/40lb setup with accessories and i can get 15min subs or more if needed and out of the box 0.6-0.7 arc second total RMS. EQ6-R pro can handle 20kg AP gear according to manual and user experience. here is my report on the setup if it helps. http://www.astronomyforum.net/astronomy-reports-forum/259561-guiding-eq6-r-pro-40lb-18kg-ap-gear.html note that this setup ( and any large OTA regardless of the weight) will be very sensitive to the wind. Also b
  12. cheap 58mm uv/it cut filter for my 55-300mm nikkor lens so i can use it with my astro modded (full spectrum mod) DSLR.
  13. thank you for checking it again. my setup was bit imaging side heavy when checking it. i may try this tutorial on DEC to reduce some backlash, its for EQ6 but heard that its almost the same for EQ6-R as well http://www.astro-baby.com/EQ6 rebuild guide/EQ6 worm alignment.htm anyone tried this or similar method?
  14. ok thanks. PHD logs don't have GA results i think. my payload is 18kg/40lb ( 10" Newtonian and accessories), i have tested things for two nights and it seems to guide well. I'm getting 0.6"-0.7" total RMS without doing anything extra like PPEC/tuning and can get 15min subs with perfect round stars so ill just leave this as it is for now.
  15. Thanks everyone for the warm welcome!
  16. Hi all, I'm from Sri Lanka. I was reading articles on SGL as a guest for a long time and finally decided to join the forums. I'm mainly focused on astrophotography, I was using an AVX and 8" F3.9 GSO Newtonian and recently upgraded to an EQ6-R pro and 10" F3.9 Orion astrograph. I have few questions about the new mount and already asked them on the EQ6-R owners club thread. Looking forward to contribute to the forums as i can. Thank you and Wish you all Merry Christmas and Happy New Year.
  17. Is this declination backlash is normal or not? It was 25,000+ms on AVX so i know that its way better than AVX.
  18. i have few other questions too if you guys don't mind. 1) home position marker. i was using an AVX and it had those marks for dec and RA clearly but EQ6-R pro don't have them in both sides. i know this is not very important but its usable when aligning the mount. is there a way to add marks accurately than using a rough position? 2) when aligning the mount and when we need to select a certain 2nd or 3rd star, we need to use bottom arrow keys to get it and most of the time its displaying "searching.." and its time consuming. sometimes its showing that for 10-15sec. is this normal? I
  19. looks like a common issue ? mine is completely off so the bubble level is not usable. I'm using the mount without extending legs so that's giving a normal level in a flat surface. I'm using a bubble level app in phone when I'm not sure about the surface.
  20. Hi guys i have recently bought the mount, its inbuilt bubble level readings are wrong. anyone have this issue? anyway to calibrate it?
