  1. The Pleiades showing different temperatures in a super unfocused image (by accident). Only after looking better to this I noticed all brightest stars are there. Love it! Stars info using SkySafary6 AVX SW80ED 700D 19s ISO12800, both images
  2. From the album: HEQ5/SW 80ED

    My first go at the Southern Pinwheel Galaxy (M83). I am finding galaxies tricky without guiding.
  3. I the surface because the surface is so boring right now. LOL These little buggers were dancing about while I was shooting some others. Thanks for the peek. Clear Skies
  4. Hello fellow gazers... I started shooting this one back on Feb 20, when i grabbed 11 x 1200s of Ha subs. 4 of the 11 were not of great quality, due to some light intermittent clouds, but i included them anyway in the stack (such is the trust i place in APP's 'Quality' algorithm). Then on March 3 i finally got another clear night, so while i waited for the sports facilities floodlights to switch off, i grabbed a short set of 20 x 90s RGB subs (just the D5300 with no filter) so i could use them for RGB stars. Then afterwards managed to grab 12 x 1200s of OIII subs. It's been a busy month (house move coming up) so i've only just got around to looking at it now. Processing this one has been a challenge. I wanted to push it hard, to show up some of the nebulosity that sits between the two nebulae, which meant the sky background became an utter pain to deal with. It was noisier than i would like, and still is, hence the need to use more noise reduction than i would normally. Having the stars in a separate layer is great, makes processing so much simpler. It has also improved my workflow i think, as i now tend to end up with an image that has 3 layers, Luminance, Colour, and Stars, rather than a single layer (which i sometimes would, due to laziness!). So now it's easier to go back and fix something later if i decide i don't like it. Full details: 11 x 1200s Ha (2" Baader mounted) 12 x 1200s OIII (2" Baader mounted) 20 x 90s RGB (for stars only) Nikon D5300 (modded) SW 80ED w FF/FR HEQ5-Pro Captured with SGP, pre-processed in APP, post-processed in PS. Ha assigned to Red, OIII to Blue, and Green was synthesized using one of Noel Carboni's actions in PS. I probably spent a good 10 hrs processing this one. Mostly due to trying to create a starless Ha image that was as clean as possible (which was a major PITA i must say!). Also, while the OIII signal was stronger than i was expecting for the tadpole nebula, it was unbelievably weak in the Flaming Star nebula. All i could get, after extreme stretching, was a small blob around the central section, so i gave up on the idea of using Annie's 'Hubble Palette Creation' Action and just went with a Bi-Colour approach. I might try the Hubble Palette just on the tadpoles at a later date, it should take to it much better. This one felt like a struggle, so i'd be grateful for any C&C, no matter how harsh. I think i have a tendency to go 'too far' in my processing, and i might well have done so here. Let me know what you think! Cheers!

    From the album: HEQ5/SW 80ED

    M8 was my first ever DSO and I am thrilled with the difference a year of practice (and better equipment) can make. 53 subs @ ISO3200.
  6. We finally got a decent active region. Now, if it will stay active during its trek across the surface we'll all have some fun. Thanks for the peek. Clear Skies
  7. From the album: HEQ5/SW 80ED

    I came across this nebula while searching for targets I had not seen/imaged before. It hides behind more famous neighbors, M8 and M20.
  8. Hi guys I thought the DSO season was well and truly over for me, but the weather's been unusually clear here in N.I for the last while that i just couldn't help myself ? So even though there is no astro dark at this time of year up here at 54 degrees N, i decided i wouldn't let that stop me try for one last target. There was also a very big bright moon up as well, so i figured M13 was pretty much the only viable target for me. Of course, with just a wee SW 80ED to work with (at 510mm FL) i knew i didn't really have the FL to do this one justice, but having never shot a Globular Cluster before i was still excited to give it a go. So here it is: Shot on May 24 from Crumlin, N.Ireland 20 * 420s with the IDAS-D1 at ISO 200 10 * 60s with the IDAS-D1 at ISO 200 All frames dithered aggressively every frame Usual gear, Nikon D5300 on a HEQ5-Pro, guided with a QHY5 and PHD2, and captured with SGP. AstroPixelProcessor used for stacking, gradient reduction, and star colour calibration. Everything else done in Photoshop. The 60s subs were used just for the core. I'm kind of pleased with how it came out. Although i'm not completely sure tbh, as this is new ground for me, and if there's one area the wee 80ED does struggle a tad with it's with stars, and with a globular there's certainly nowhere to hide on that front! Also attached is a 100% crop showing just the globular cluster itself. C&C most welcome as always. Cheers guys!

    Prawn Nebula IC4628

    From the album: HEQ5/SW 80ED

    Another nebula just outside the Messier range.
  10. Here's that prom that's been hanging off the lower east limb for a couple of days. This was my first chance to shoot it... still dodging light clouds. Managed to save a small plasma lift-off below the prom. Thanks for looking. Clear Skies
  11. Here's another prom from the east limb today. Thanks for looking. Clear Skies
  12. Hi there, I have a skywatcher Evo 80ED ds (black & white one) and .85 reducer coupled to a canon 500d . i've been saving up for a new focuser and im torn between choosing the moonlight or steeltrak model. hmmm Also my sw .85 F/R screwed onto the stock focuser thread after taking off the 2" ring , on these fancier focusers, do i need to fit the reducer with an adaptor with 2" nosepiece or is there a step down thread ring available ? Dave.
  13. Here's a nicely formed hedgerow on the sw limb yesterday. Thanks for the peek. Clear Skies
  14. After almost a month of misery (the last clear nights in Melbourne were during the last full moon) I had two night to have a go at M83. Without guiding I find galaxies challenging but I am quite pleased with this effort. Total of 148 subs @ 60" each, ISO6400 with and without the Baader UHC-S filter. Clear skies! HJ
