  1. Hello everyone, Bit of a backround: I've been a keen stargazer when in my teenage years, then couldn't pursuit my passion, but recently, in my forties, it hit me again, as I moved and life is good (South facing large garden, obstructed only from the North by our house, but then I just move the scope further and viola!). Started with 90mm refractor, but was always thinking of reflector. Long story short, I've got my SkyWatcher Star Discovery 150P GOTO a week ago. Bought it second hand, very good condition, and good mirror. Have got two nights stargazing, cought cold and I AM LOVING IT. Now I would like to get me a nice wide angle ep for DSO spotting. The scope is 150mm / 750mm f5. I've done some reading obviously, and Explore Scientific 82 degree series have all good reviews and fit within my budget. I can afford only one, and apparently the best for DSOs is the one that gives 2mm exit pupil. Now, for my scope that would be 10mm piece, and that is not within ES 82 degree range, so it's down to 11mm (2.2mm exit pupil) or 8.8mm (1.76mm exit pupil). My question is: which one would be better for my rediscovered passion? I'm gonna be using that ep for faint mostly. Thanks to everyone in advance for any kind advise.
  2. The Wizard Nebula An emission nebula 7,200 light years away and my first proper project of the new imaging year. Really happy with it as I’ve had a steep learning curve with new kit so really pleased to see this image come together. It’s also the first time I’ve imaged it. 72x180s subs collected over 2 nights 24/25th August in my Bortle 7 back garden, Whitley Bay, England Calibrated with darks, flats and dark flats in DSS and processed in SiriL and Photoshop. Lacerta 72mm f/6 APO ZWO ASI1600MC Pro at -15C gain 200 iOptron CEM25p ZWO 60mm guide scope ZWO ASI120MM-S guide camera Altair Astro 2” Tri Band OSC Filter Data collected in APT and guided with PHD2
  3. The Needle in RGB A beautiful edge on spiral galaxy in the constellation Coma Berenices, around 38,5 million LY from earth. Investigations with the Spitzer IR telescope suggests that the galaxy may actually be a barred spiral galaxy with an inner ring as well. -------- Finally got around to processing my data on NGC 4565 from March. This was one of my "test projects" from this year, where I only shot R-G-B and created a synthetic luminance master from those frames. I think that the most efficient way is still to shoot pure luminance and then just enough R-G-B to get the color you want. Unless one is imaging star clusters, then I think it is totally fine to skip luminance altogether and get as much color data as possible. I will try to do a "super luminance" where I add the R-G-B frames to the luminance stack at some point as well. Shot with my Hypercam 183m V2 and totalling aroung 4,2 hours of data. More info here: https://www.astrobin.com/412663/B/ Comments and critique is always welcome. I decided to put this post in "Getting started with imaging" as it may be interresting for beginners thinking if luminance is worth it.
  4. Hi everyone - it's been a while! This has been on my hard drive for almost 2 months and I finally got round to processing it...it was quite optimistic of me to try and image this from my Bortle 7-8 back garden, but I gave it a go! While the nebula itself is clear to see, all those gorgeous dust clouds surrounding it were extremely hard for me to capture from my location without a lot more integration time. I think I'll head to dark skies to capture this one next time, along with some more focal length! LRGB shot with ASI1600MM Pro and WO Z73. 2.9 hours of integration time. Full details here. Thanks for looking!
  5. This is a recent edit of data I collected back in January. Image is taken with a Canon 450Da and Canon EF L 70-200mm f/2.8 lens sitting on a Sky-Watcher Star Adventurer. It’s quite a large crop from a 200mm frame. 25 x 3 min guided subs. Stacked in SiriL and processed in Photoshop. Image taken in Northumberland under Bortle 3 skies.
  6. Hi everyone! The Tadpole Nebula and the Flaming Star Nebula captured over three nights of the unexpected nice weather we had a couple of weeks ago. A number of firsts with this image: 1. My first mosaic - keeping it simple with two panes! 2. First time I left my imaging rig outside... (I used a telegizmo cover) and it was perfect, allowing me to get imaging very quickly on each night 3. First time using powerful scripting tools in my capture software, APT, to move to the second pane and starting imaging automatically...worked really well! APP was used for pre-processing and stitching the mosaic together, while Pixinsight was used for image processing. A total of 10.9 hours integration time. Full details on Astrobin Thanks for looking!
  7. C11 with focal reducer (1760mm), ASI183mm Pro. Astrodon filters. Mesu 200. Pixinsight. 80 x 60s L 30 x 60s RGB 2.8 Hours data. Thanks for looking. Dave.
  8. Heyyy its meee kronos and i have been wondering about getting a filter...I really want the best contrast and brightness i can on my nebulas(i want to view M42 M57 M27 M31 M81 M82 and lots more) with my future 8" dob. Is this filter really going to help me? https://www.firstlightoptics.com/uhc-oiii-visual-filters/es_uhc_filter_125.html If it just a matter of quality of the filter itself can you suggest a better one in the same price range? Or will not the uhc filter help me in general .IF so can you reccomend another one? Also is this https://www.firstlightoptics.com/uhc-oiii-visual-filters/uhc-filter.html this https://www.firstlightoptics.com/uhc-oiii-visual-filters/es_uhc_filter_125.html https://www.firstlightoptics.com/uhc-oiii-visual-filters/baader-uhc-s-filter.html this better?
  9. M1 Crab Nebula taken 7 Oct 2018 from my garden. ZWO ASI 183mm Pro C11 on Mesu 200 12 x 120s subs for each RGB. Processed in Pixinsight.
