  1. Clear last night so had a go at the Jellyfish. Found this one quite tricky due to faintness and light pollution here. Taken with my ED80 and Canon 1200d. Then I did a widefield shot of the same area using my Canon 550d and Samyang 14mm. Some detail lost in saving as JPGs. Any comments as usual. Peter

    Jellyfish Nebula 3x

    From the album: Deep Sky

    The Jellyfish Nebula (IC443), the remains of a supernova in the constellation of Gemini. It is about 5,000 light years away and was created sometime between 3 and 30 thousand years ago. Also top centre is IC444 which is a blue nebula due to starlight being reflected off gas and dust. (No sign of SpongeBob or Patrick though). Seeing was particularly good on this night. Imager: Sky-Watcher Evostar 80ED DS-Pro, Sky-Watcher 0.85x Focal Reducer, Canon EOS 500D (Unmodified), Hutech IDAS LPS P2 2", APT - Astro Photography Tool Guider: Orion ST80, QHY 5, PHD Guiding Mount: Sky-Watcher NEQ6, AstroTortilla, EQMod Processing: PixInsight 1.8 Dates: March 1st, 2014 LIghts: 13 x 600seconds ISO400 (2.2 hours) Darks: 109 Flats: 102 Bias: 330

  3. @Stu, @GavStar and myself met up for a bit of club observing Thursday night… cloudy so good that we met down the pub. Someone (not sure who) pointed out it was clear, so we headed out to stand and chat under clouds with a chill breeze for more than 2hours waiting for the skies to comply with Sat24. Finally we spotted what looked like the edge of the clouds… the others got ready to polar align. OK observing under a near full moon is not ideal.. but it does help with setup and checking your charts! So what to look for… using Gavins new “magic eyepiece” we headed straight for the Horsehead, just visible, the flame slightly more so above. We were using a TEC160 on a goto panther mount, with 55mm plossl and the TNVC adapter to the intensifier, using a 6nm hydrogen alpha filter to “help”. The gain control worked really well to tune the balance of brightness (and noise) vs detail. The “white phosphor” giving a very neutral and “natural” view. Right, where next? Up to the jellyfish ic443, nice gentle curve easily visible, checked on the monkeyhead nearby. We then cruised down to the seagull which filled the view and then tried to ferret out the medusa Nebula… it evaded us this time. Swept over the the pacman, the heart and then the California nebula. The latter as two broad nebulous bands crossing the field of view. We need to try a smaller scope to give a bigger field of view for these really big nebulae. Swapped in a longpass filter and checked on M35 which looked great, M3? and then M81/82, very clear dark lane in the latter.. Clouds finally made a return and we packed up the wrong side of 1am, feet nearly frozen solid. Seemed like many of the streetlights had turned off as well, which is interesting to note. Going to be fun to poke this setup at nebulae when the skies are a little bit more conducive to observing. PeterW
  4. Hi Everyone, This is my first NB image - 16x600s of Ha plus 16x600s of Oiii - Sii will have to wait for another long, clear night. I went with the blended channels approach in PixInsight 100% Ha in R, 40% Ha + 60% Oiii in G, and 100% Oiii in B. Using 100% Ha in R and 100% Oiii in G and B resulted in a very red nebula and a distinct red tint to the background. Any help or suggestions on how it might be improved would be much appreciated - I essentially followed the LVA tutorial. Thank you for looking. Adrian

    Narrowband, Ha only each frame is 20 mins exposure at -10 degs 41 x Ha
  6. After my last attempt at HaRGB on the Horsehead, I have decided to concentrate on narrowband for now from my semi-urban home. I have had a go at the Famous Jellyfish Nebula in Ha with my trusty 150 pds and SBIG 8300m with the Baader 7 nm filter. After looking at the efforts of others on varying targets, I have come to the conclusion that even narrowband benefits from darker skies! 16 X 1200 seconds. Processing was mainly just stretching in PS, but I had a go at the mure de noise script in PI first, as demonstrated by Gnomus and Barry ( https://stargazerslounge.com/topic/262808-another-rosette-wo-star-71/ ). I still think it's a little waxy, but not excessively so, and it did allow me to stretch it that little bit more before the histogram turned into a profile map of the Dolomites ;) This might be my last with the 150 pds for a while as I'm off to Essex to collect a WO Star 71 today!!
