  1. How do I change horizon colour in CDC?

    Easy peazy .... Go to Set-up tab at top .... then "Display" .... then "Colour" .... you can choose a whole range of colours :-) Mike
  2. My second attempt at imaging this comet last night .... only using 9 x 300sec CLS subs and tracking the movement of the comet as it moved past the stars. It is not a good final image .... but I am amazed just how much the comet moved in the space of 60 minutes!!! This comet is pretty faint (mag 13'ish) but I am becoming hooked on imaging Comets .... can't wait for a brighter one to crop up! Mike
  3. Don't know ... I am new to all of this :-) But I do know that C/2016 R2 is moving away from the Earth and won't be this close for another 20,000 years ! Mike
  4. This is my very first attempt at imaging a comet. I managed to grab two sets of images on two consecutive evenings this week .... I am amazed just how far the comet moved in 24hrs. On each night I took 5 x 200sec CLS subs and 3 x 100sec RGB subs. At least I can see some evidence of the tail ... but I had to stretch my final stacked images to get there. Any suggestions on how long my subs need to be to bring out the comet's tail better .... assuming that I get another clear sky before the comet gets too faint???? Mike
  5. Well I re-did all of Flats today and reprocessed my original subs .... Obviously some dust motes had got into my system. I think my final image is a definite improvement .. and I am still amazed at how much data I got under such poor conditions ! Thanks for the helpful comments. Mike
  6. Yes ... it looks like I need to re-do my flats .... I last did them about 6 months ago. Mike
  7. I managed to grab 2hours worth of imaging of M38 last night despite conditions not being very favourable passing high clouds, several thick aircraft contrails and a bid Moon not far away. I must admit I did the imaging just to see how things coped in these conditions and nearly didn't bother. I did 9 x 500sec CLS subs and 5 x 300sec RGB subs .... calibrated and stacked with MaximDL and processed in PS. I am pretty pleased with how my final image turned out despite the conditions Mike
  8. IC 443 ... Jellyfish Nebula

    By doing a bit of "cutting & pasting" I have now combined the best of two versions and managed to retain the unclipped histogram (see below) .... I think this version is as good as I am going to get it .... for the time being anyway Mike
  9. IC 443 ... Jellyfish Nebula

    Hi ... what you have all said is interesting. I must admit I wasn't taking a lot of notice of the histogram when I was trying to get the star bloat of Eta Geminorum under some sort of control. Looking back at a previous processing effort (see attached) I can see that the histogram is not clipped so badly .... but Eta Geminorum is over powering :-( That's when I started to "play" with things. I have lost track on what I did after this to cause the histogram to be so clipped. Mike
  10. IC 443 ... Jellyfish Nebula

    After dodging endless nights of thick clouds and rain for the last few weeks I have managed to get some of the longest duration subs that I have done so far to see how my system copes. The attached image is of IC 443 .. "The Jellyfish Nebula" ... images being taken over three widely spaced evenings. I managed to get 12 x 1200 sec CLS subs and 7 x 300 sec RGB subs. The subs were calibrated and stacked in MaximDL and processed in Photoshop. I have to spend quite a lot of time trying to control the overpowering bloating of the large star at the bottom of the image (Eta Geminorum) but this is the best that I could get so far. My night sky here in Nottinghamshire is not good at the best of times but I am reasonably happy with my results so far. Any suggestions that will help me produce clearer images in the future would be welcomed as always :-) Mike
  11. Thanks Martin and Dave .... just what I wanted :-))) Maxim has another stacking method called " SD Mask" .... still not sure what the pro's & con's of this method is. Mike
  12. Hi .... After "test stacking" some of my subs using all of the stacking methods available in Maxim DL and comparing them I can hardly see any difference between most of them to be honest :-( Can anybody give me some idea of the pros & cons of the different the stacking methods available in MaximDL? The manual does not seem to be very clear about this and not very helpful to be honest. At the minute it all seems to be hit & miss which method I actually end up using and making very little difference to the end result. I do know that the Sigma Clip method is very useful for removing plane and satellite trails from stacked subs. Mike
  13. Wifi in obsy...

    I did forgot to say that I had to learn how to wire up the Ethernet connectors at both ends of the cable ... quite fiddly until you get used to it! It took quite a few test runs to get the technique right but I get there in the end. Also I did have to buy a special tester to see if I have wired up both ends of the cable correctly (cost £5 I think off Amazon or eBay) .... but the total cost of this fully working set-up was no more than £50 ... for the cable, connectors and tester, etc. Mike
  14. Wifi in obsy...

    Mu Obsy is approx. 40 yards away ... I tried powerline adapters but they didn't work over the ring main that I have rigged up. I did toy with the idea of WiFi a "line of sight" transmitter and receiver units ( and being careful to avoid some potential tree problems ) and even put some cabling in from a possible receiver position near the Obsy. However in the end, with quite a bit of effort as it wasn't a straightforward route, I managed to put a weather proof Cat5 Ethernet cable from the router next to my house computer down to the Laptop in the observatory. Works great :-))) No problems at all ..... provided I keep my eye on unwanted and unexpected Windows 10 updates coming out on the Laptop!!!! Mike
  15. My first NB - IC443 - I've much to learn!

    Hi Adrian .... can I ask what this "LVA Tutorial" is ? .... and where can I find it? Mike
