The visible remains of a star that died around 10,000 years ago, the Helix Nebula ( NGC 7293 ) is one of the closest and largest of the so-called planetary nebulae that are observable from Earth.

Situated in the same arm of the Milkyway galaxy as ourselves, the Helix Nebula is around 650 light years away, is growing at a rate of over 100,000 kms / hour  and is currently around 2.5 light years across.

      I'm tempted to go down the route of getting myself a brand new reflector...  My friend's old Meade 114/900 is a good telescope, but I want something of my own and with a bit more light gathering power.  To this end, I've been looking at a couple of different models and manufactures.

      I must admit, the Skywatcher Explorer 130M floats my boat, as it's motorised with a speed controller.
      Any thoughts or observations?🤔

      Celestron C8 XLT + extras and SkyWatcher Star Travel 80 (ST80)
      I have a Celestron C8 with XLT Starbrite coatings. Will include the full length base plate, both visual and imaging backs, scope rings, front 8" end cap and the finder scope with it. No box I'm afraid. Optics are good and clean, focal length is huge - 2300mm from memory. This lot would cost close to £1300 new and one with less spec went for £750 on fleabay recently. Might be interested in a part exchange or will let it go for £450 collection only.
      Also, I have a SkyWatcher Star Traveler 80 - good optics, used as a guide scope - just the scope itself (does not include the barlow in the photo) - now including dovetail bar and scope rings looking at around £50 for it.
      I have decided to save up for another refractor, WO, Equinox or even toward an Esprit. However, I would also consider p/ex for an Intel NUC and/or Pegasus Astro Pocket Powerbox.
      Please excuse some of the colours - I used my astro modded 6D which was in the observatory so the "nice" purple is actually black !!
      Both these are collection only.

      Is the Nikon Nikkor 55-200mm f/3.5-5.6 II a good lens for astrophotography? I plan on using the Nikon D5300 with it and I wanted to know if the 55-200 would be a good lens for photographing DSOs. Does anyone use this lens and if so, may I see some images taken with it? I can't seem to find images on Astrobin. Also, is it possible to photograph DSOs (M42, Rosette, Flaming star, M45 etc.) from a bortle 7 sky with the 55-200mm?
      Clear skies,

      These are my last images of 2019 taken with my ED72 and 183mm pro to be replaced by a 533pro
      These targets are not easy due to location trees etc except M1 , there was a bright moon as well so are all lucky shots
      but at last i have taken them warts and all . My guiding was all off as well
      Anyway a merry Christmas to you all and a Happy new year

      I am going to buy Skywatcher EQ5 Pro Go-To mount. But, unfortunately, I am low on budget.
      So, does someone know where can I buy the cheapest EQ5 pro mount?
      Yesterday there was a low price for it (350 €), but they changed it.
      Thank you for your time!
