  1. Thanks Martin. I have to be honest, I'd never noticed the tail before I processed this and I first thought there was something wrong in the stacking because of the straight line at the end of cloud above it. Definitely worth trying it with all 900mm FL of the scope on the next clear night.
  2. One really clear night up here on 4th March, so I made good use of it. Firstly I started on M42 and managed 22 minutes, between trees. The results are in another thread in here. Then switched back to NGC2244 and got more data on this target to add to data from a couple of nights ago, then this started heading behind the trees as well. So I managed 2 hours on M51 (24x300s). The kit is ZWO ASI294MC Pro cooled to -10°C and gain of 120, SW Evostar 100ED Pro on a EQ5 mount using PHD2 & APT. Stacked with darks, flats & dark-flats in DSS & post processing in PixInsight.
  3. Well here's the slightly longer exposure. This one is 22x90s (33 minutes total) using the same settings & kit as in the first post. I had more issues with the core on this one and could have done with some 30 or 45 second subs to reduce the core. But it is what it is and I took it to where it looked okay to me. There is more in there but when I brought it out it just didn't look right as a whole, so I ended up with this. There is more dark detail in this one and it was a really clean image, hardly any noise reduction required, even though I managed to introduce some in the
  4. I managed to get another 17 x 90s exposures last night, although I may have to ditch a couple due to the trees. Hopefully I'll get these stacked and processed this evening and include the 7 from the other night. I'll post up the result tonight or tomorrow.
  5. I've just noticed that I missed off one detail from the original post that may explain the good data: I do live in a Bortle 2 area, so no LP to contend with and the only filter on the camera is a UV/IR cut.
  6. It shocked me too! I though there would be some of the main nebulosity in there but never expected as much detail with the dark dust. I also thought the centre was blown out but when I reduced it with curves the stars & dust detail came through. I'm back on it just now and will get some more data at 90 & 45 seconds to add to this and see what else comes out.
  7. I last imaged M42 back in 2012 from the Isle of Lewis. Since I started back into the hobby last year it has been hidden by trees and hills in my new location, so I only get a brief glimpse of it each night. Last night I decided to have a go and see what I could get. Not much as it turned out because I messed around lining up and trying 180 second exposures (too long) so settled on 90 seconds. By this time I only managed to get 7 subs of 90 seconds before the trees started to act like a Bahtinov Mask on the image, so that was end of that for the night. Tonight I thought I would stack
  8. I have been following that thread and saw your images. That's a good result under a "Almost full moon (no head torch needed to read a book) ".
  9. As I understand it (and I don't mind being corrected as I'm always willing to learn ) the UHC is too wide in it's transmission curve to reduce or stop Moon light. It's good for artificial light but Moon light is not in wave lengths blocked by this particular filter. Where I am, I don't think I would see any significant benefit under a full Moon. The L-eXtreme has a 7nm pass in Ha & Oiii meaning it is very tight on what wave length can pass. The likes of the ZWO duel-band filter also focuses on Ha & Oiii but at a wider 35nm pass on both, meaning Hb is also within that pass band. F
  10. Now that's good and with an unmodded camera as well! It's bright moon light I have problems with as it seems more pronounced with less LP, so that gives me a idea of what to expect from the L-eNhance. Thanks.
  11. I gave up at about 21:30 last night when some thicker bands of cloud came over from the East. It cleared again at a round 01:00, but I had work this morning. I love the dust detail you've captured with the Ha, David. You can almost see if moving!
  12. I'm on the look out for a filter to assist when clear skies coincide with the full Moon, which seems to happen regularly here. New Moon = cloudy, Full Moon = clear, you know the drill. Anyway, research to date hasn't come up with any conclusive answers so I thought I'd ask the good folks on SGL. I'm lucky to live in a Bortle 2 area, so LP isn't an issue and normally I only use a UV/IR cut filter on my ASI294MC Pro Cooled camera. I mainly image nebula and the full Moon makes that difficult so I want increase my useful imaging time on these targets so I can combine with subs taken wh
  13. Finally had a clear few hours this evening after a very clear day. This gave me a chance to see what difference I'd made to my scope & mount. The SW Evostar 100ED Pro had the focuser tuned (taken apart, cleaned, the flat on the focuser tube ground flat, assembled and adjusted). The SW EQ5 mount had the same treatment over the weekend with a full strip, clean, new bearings, re-grease and assembled again. The focuser performed very well, it use to change focus as I tightened the locking screw because of slack. Tonight is took five adjustment to get focus! The jury is still ou
  14. In what way is it loosing control of the RA & DEC, are there any alerts on PHD2? A screen shot may help, also if you could upload the log file as well. Have you calibrated PHD2 before you start guiding, it asks you when you start for the first time but then you can hold the Shift key down as you click on the Guide button (round green target) and it will open the calibration window. Once calibrated, it's also worth running the Guide Assistant in PHD2 and leave it for about 5 minutes, and include backlash, to see what recommended settings it gives you.
