  1. Im looking at a new scope to do some planetary imaging (Jupiter and Saturn) and hopefully it would make a good galaxy scope too and to be honest I’ve been going round in circles. I’ve just been brought a ZWO 224mc and seen that the ADC is a good choice to improve imaging, so thats on my list. Please any suggestions pros/cons? I would like to be able to do some visual with it but only as a secondary option. These are a few I’ve been looking at, but not limited too. Celestron edge hd 11 - but have read about mirror flop, so would add a moonlight focuser and need to do collimation, and right at the top of my budget. Skywatcher Esprit 150 ED PRO Triplet - should be a lot easier to use, but doesn’t have the focal length of the others. TS 12" f/8 RC astrograph - a true Ritchey-Chrétien telescope with 304 mm aperture and 2432 mm focal length - But again collimation and can’t find out much information about this scope. Really happy with my wide field TS optics scope. Newt - open to ideas and suggestions and know this will also need collimation. And any other scopes I should consider? one thing I’ve learned is there isn’t one size fits all. I've never had to do any collimating, and not sure how much of my limited time this would take up and how often it needs doing. But happy to learn this if the scope I choose needs it doing. Any advise/suggestions would be welcome, even if I’m completely off track. Thanks in advance.
  2. As above, I'd like to thank you all for your help, this hobby is very challenging (I like a challenge) and when you are muddling by, without the knowledge, it's hard to work out if it's something your doing wrong or a problem with the kit as in this case, and allinthehead without your help i'd have gone on thinking it was as it should be or the problem was elsewhere, the shop got back my faulty camera yesterday and confirmed they were seeing the same thing. I would like to thank First Light Optics, for great customer service.. They are loaning me a demo unit while mine gets sent back for repair. And even offered me to keep it if I like as it hasn't been used much, I am condensing this. Loan camera will be with me today. That is great customer service in my book.
  3. Thanks for everyone’s help and advice, I have emailed the shop, earlier today.. They replied and said they have never seen this before. I have emailed them more dark subs as requested and they are speaking to ZWO. I hope I get a quick out come as I’ve been waiting for the winters sky.
  4. Thanks for your replays, here are 2 screen shots, look's like latest drivers installed. The camera is 2 weeks short of one year old (only just got round to using the camera, had all intentions last year, but a new baby put stop to that lol) if these settings look fine then will get in touch with UK supplier
  5. Here are some pictures of my setup and I have just taken a 10 minute sub Dark at unity gain at -20c. https://www.dropbox.com/s/6bpwu5o4000pmkx/Target 1_600sec_1x1__frame1_dark.fit?dl=0 Due to not being able to get some of the metal ring pieces a part to fit the dust cap to front of camera (I have ordered some strap wrenches for tomorrow, good old Amazon), I had to loosely place dust cap on front of camera nose down like shown in the attached picture, but did place camera at the back of a draw and managed to close it other then the usb cable coming out the front side, very small gap, I had a battery in the draw to work the cooler and was set to -20c This was a new usb 3 cable, do you think I have a problem with the camera?
  6. Thank you too, yes there seems to be a large difference in dark frames between mine and yours.. My dark's were taken in a brightly lit office (not thinking this would cause any problems) as it was attached to the scope with the cover on. I will take another dark tonight, just camera only and as you described, I will do both a 60 second (as mentioned by Richard) and a 600 second sub and post here if you would be good enough to look for me? Thanks David
  7. Hi Richard, thank you so much for your fast reply. I took my darks in work, telescope wasn't covered, just on a bench and set to -20c I will try another usb cable, although it was a different cable that I used to take the Darks and Bias. I will try this tonight when I get home from work, using a different usb cable, if I upload this here would you mind taking a look at the dark frame? What gain would you suggest? Many Thanks David
  8. This looks a lot cleaner, I haven't tried another scope although I still have my Skywatcher Evostar 80ED I could use.
  9. Hi, interesting you say that.. To be honest I really not sure what's going on.. At first look at the processed subs it looked a lot better but yes I think you are right about it masking the problem. I do live in an extremely light polluted area. Here is a single sub, dark and bias, if you wouldn't mind looking? https://www.dropbox.com/s/0yj04ez864n2j3g/Target 1_600sec_1x1__frame1.fit?dl=0 Dark https://www.dropbox.com/s/yz8gd8ar0a58fdo/Target 1_0sec_1x1__frame1.fit?dl=0 Bias https://www.dropbox.com/s/bzqj7t2dw6nn2ya/Target 1_600sec_1x1__frame11.fit?dl=0 Light
  10. Bingo!! Thank you to everyone who contributed to this thread, Dark and Bias frames was all what was needed.. I'm so happy it's nothing more then that.
  11. Hi, I have started imaging again after 2 years of not getting a single result.. I have all new equipment after having an unsuccessful time last year in my limited windows I get, last year was written off due to technical problems (mainly me). And almost gave up then. I moved house six months ago and have a good view of very light polluted E,S,W sky, but due to small size of garden and various building, I need to be either at one end then can see North or other end and can see South of my garden, no real middle ground, so Polar Aligning has been a challenge, but I think i'm pretty close and I'm leaving the mount outside but covered. Here is a screen shot of 11 x 10 min HA subs from Sunday night.. Stretched in PS I was having problems over in this thread, but thank you to all those that offered advice, here is the 11 x 10 mins subs, with Dark's and Bias added.. It's only a start, but it got to the point of having no success for 2 years and I had tried several times without any luck recently with new equipment, that if this night proved another wasted evening I was going to sell the lot.. So feeling relived at getting some kind of image.
  12. I'm just making a dark's library, i'm doing 20 of each exposure. Probably start with 2,5,8 and 10 minutes. At -20c which is what I use. I'm currently in the middle of my 10 minute ones, the camera is set to -20c, and the lens is covered up, and the filter is set to HA. Does my dark's library need to contain dark's for each of my different filters? Or does it not matter about the filter?
  13. That's interesting about the unmounted filters, wish I knew that 10 moths ago, would have saved a fortune.. I thought a bigger filter would be better at the time, I can live with some problems around the edges of the image I guess. Yes I do have a copy of PixInSight (whole new learning game), so will try that and thanks for the suggestions
  14. Screen shot of my work flow at the time using SGP, just in case there is something obviously wrong, unfortunately you can't see the problem with the image in the background as it was not centred in the frame to show the problem at the time.
