  1. Testing my new setup - Heart Nebula

    Did a bit of editing. Getting more of the blue/gold scheme now, but starting to get a lot of red at the peripheries. Any suggestions? I know I need to collect more data anyway, as this was just a test run. Not a problem at all, appreciate your help. In the first instance I actually bought an 80mm extension tube initially as I couldn't get focus. Then once I bought the spacer afterwards I found that the extension tube became redundant as the spacer was all I really needed. It really can become an expensive hobby quite quickly!
  2. Testing my new setup - Heart Nebula

    Thanks for the link! I've tried that method but I'm trying to do a lot of my processing in Pixinsight. Any Hubble palette tutorials for that available to get a good blend? Not satisfied with any I've used so far, been trying a few different ones in PixelMath. Thanks! As mentioned in my original post, I've already fixed the issue; I knew it was a spacing issue because there was trailing only at the edges, and figured I needed ~25 mm of extra spacing but there was some uncertainty as to the exact value; managed to find a Baader Varilock which has solved all issues very nicely. Nice round stars in all corners now.
  3. Having recently acquired a WO GT81, I've been sorting out teething issues to make sure everything is working well before the nights start drawing in. Did a test run for the Heart Nebula and figured out my spacing was off as I could see significant trailing at the peripheries; seemed unlikely to be due to guiding as the image centre was fine, and it turns out I was correct; increasing the spacing by 25mm has done the trick. Processed the dataset anyway, turned out ok I guess. Ha 25x300s + OIII 15x300s + SII 12x300s - Total integration time 4h20mins. I'm now starting to go down the route of lower exposure time + higher gain + stacking more subs to recover more bits; it'll drop dynamic range but you can't have it all I guess, especially in the UK's weather. Hopefully a Heart & Soul mosaic is on the cards with 180s subs, we'll see how that goes with OIII/SII though! This is also the first time I've done a tricolour narrowband combination, and it's proven to be fairly tricky! I'm fairly happy with the colour in this one as I wanted to keep the processing as soft as possible, but lots to learn still.
  4. Sorry about the delay everyone! All items are still available. I have private messaged everyone as well. Cheers
  5. Baader SII 8nm 2-inch mounted filter

    Found.
  6. Hi all, I've upgraded my setup, and so putting my Skywatcher 80ED and accessories up for sale. All items have been looked after well, and have the usual marks of use; any major issues are outlined below. Prices are excluding postage. Payment via Paypal preferred.Skywatcher Evostar 80ED DS-Pro doublet refractor with tube rings + dovetail bar - The issue with the scope is the eyepiece/accessory holder; the locking screw threads within this have pretty much disappeared, so I installed a Baader Clicklock clamp instead, which has worked with my field flattener, 5x2" filter wheel, and ASI 1600MM-C flawlessly even pointing up to zenith. If you do want to use it without the Clicklock, I'm sure AstroBoot could source a new holder, or FLO have these in a new compression ring version for £29.90. I personally wouldn't go to a either of those after using the Clicklock! There is also some marking on the logo, but nothing that affects viewing/imaging. SOLDSkywatcher 0.85x Field Flattener/Focal Reducer - Allows imaging at f6.37 by reducing the telescope’s focal length by a factor of 0.85x SOLDSkywatcher Aluminium Carrying Case SOLD Baader Click-Lock 2" M56 for Celestron & Skywatcher - Superb piece of kit, provides a rock-solid grip on equipment SOLD FLO Adapter for Skywatcher Focal Reducers - Fits the Skywatcher 0.85x FF/FR and allows connection to a 2-inch focuser tube £15 Revelation Self Centre 80mm extension tube 2" - Only purchased a couple of weeks ago, not required as all I needed in the end was a spacer; has a couple of thumbscrew marks £18 Revelation 2-inch to T2 mount adapter - Allows attachment of DSLR to 2-inch focuser £10 Skywatcher autofocuser + HitecAstro DC focuser - Allows electronic control of focuser using ASCOM interface £75 Maplin Portable Power Pack with 12V Modified Sinewave 200W Inverter - £25 (will have to be collected due to nature of item) EQMod Bluetooth Adapter for wireless control of NEQ6 Pro mounts - I've tested it on Windows 10 and 7, works fine. I've also created a small plastic housing for it to protect it from damage £20 Pictures available here: https://drive.google.com/drive/folders/0B12lFcbG64vNS0QwUzVnaUhlMTg?usp=sharing. Happy to send more close-up pictures if there is any interest. Cheers, Syed
  7. Hi all, Looking for a Baader SII 8nm 2-inch mounted filter. Let me know if you have one and its price. Cheers, Syed
  8. UK skies

    Currently imaging Elephant's Trunk in OIII! My Ha subs have just been sitting there waiting to be combined with some OIII and SII.
  9. Camera Upgrade Itch

    Considering you have the funds, you'd be crazy not to get it! I'm not helping am I? Second-hand 2 inch filters can be had for pretty reasonable prices; I managed to get an almost new Baader Ha 7nm for £116 and an almost new OIII 8.5 nm for £85 including postage. Hoping to get an SII for the same as the OIII, so that would be ~£270 for all 3! Considering a new set costs ~£420, that's pretty good; just need a bit of patience I guess.
  10. ASI1600mm cool

    Cheers Andy! I've been using a Baader 7nm Ha for the above, and have recently purchased a Baader 8.5nm OIII (and of course the clouds came without delay). I'll be sticking to Baader as they're tried and tested, and I've managed to get very good prices for almost new filters via ABS; I was considering Astronomik, but there tend to be fewer of those second-hand, plus I read that there's only a 1mm thread which could cause issues with my SX USB filter wheel. No problem! I agree that the switch from DSLR to CMOS or even across different CMOS/CCD sensors can be tricky. I'm quite happy with unity gain so far, but it won't be long before I start going up to 200/300 gain and seeing whether I can get more detail with 300s subs on fainter targets. I did quite a bit of reading about gain and offset in the 1600MM-C from various forums and decided to stick with unity gain since I'm only just starting out with a CMOS.
  11. ASI1600mm cool

    Thanks! I actually bought the 1600MM for precisely that reason, considering LP and the weather here. The elephant's trunk was my first session so I was trying to push the camera and see how it would perform at subs beyond 300s. The pelican nebula is combination of 180s and 300s subs. I'm going to experiment with 200 and 300 gain at some point and see how that works out. Everything was done at unity gain (gain 139, offset 21). Cheers
  12. ASI1600mm cool

    Cheers! Skywatcher 80ED DS Pro; hoping to upgrade to a triplet apo at some point in the future.
  13. ASI1600mm cool

    I received my 1600MM-C a month ago, and have been imaging intermittently. I have to say I am thoroughly impressed so far. I am using no calibration frames at all and subs of up to 10 minutes, with 2-inch filters. These are a couple of my results, both in Ha. I've recently purchased an OIII filter and am on the lookout for an SII filter, so will go full narrowband soon hopefully. Too much LP to bother with LRGB for the timebeing. It's important to note that these images have not been processed at all, apart from a histogram stretch in PI. Pelican Nebula - 3-panel mosaic (work in progress), total of 4h22 mins of exposure Elephant's Trunk Nebula - 12x600s
  14. OIII filter found, still looking for SII 8 nm!
