  1. When I did it in November I worked on the outer stuff and then masked up the centre to get the detail, with my skies it was hard to pull any more data from the background, but with your superb skies I am sure you will pull a beautiful image. https://www.astrobin.com/vpgt3u
  2. Yes as Rich say pixinsight really is superb, and it has taken me about 3 years to get comfortable with it, far from perfect, but my old brain isn’t as sharp as it used to be, but with a youngster like you Vicki, you’ll fly with it.
  3. Hi Brian, I thought there was loads of dark stuff that you were missing out on and sure enough there is loads, just had a quick play and yep its there, just needs tweaking out: - I'm sure there is loads more to pull out and with your skies it will produce a wonderful image.
  4. You have done a lovely job with that Vicki, a little hint that I find I am using more and more now and your image is crying out for it, extract a lum mask, apply it and invert it, then bump that saturation up, it will bring the colours through without ruining the background. It was my nemesis as well and I failed the first time I tried and finally managed a reasonable image about a year ago. HTH
  5. Welcome Chris, I hope you find this a pleasure to be a member of, we are really a chilled out bunch with a common interest. I can honestly say that there has been hardly any need for any moderation, in fact I am redundant 🙂
  6. Welcome Rich, I hope your enjoy it over here, it's a nice easy going forum, which is exactly how we launched.
  7. Thanks Vicki, appreciate your comments.
  8. Welcome Tom, please enjoy this friendly forum.
  9. Hi Craig, welcome, hope you enjoy it over here!
  10. Hi Andy, welcome to the forum, enjoy!
  11. Welcome Galileo, I hope you enjoy your visits here.
  12. I had an AZ-EQ6GT, and really wasn't happy with it, terrible backlash, horrible protruding adjustments, poorly made, I sold it about 4 years ago and bougth a CEM60, absolutely brilliant, I only upgraded to the 120EC because I was offered a deal I couldn't refuse. I bought then a 40EC for my travel setup, but have also been using it as a setup in my garden rather than my observatory and it works superbly. Sad to say I would not touch a SW mount in future unless they had made some major leaps forward in design.
  13. Hi Bryan, I don't know the connections for the CEM26, I can only tell you how it works for me. I don't use the hand controller or a URS232 cable, the new cable plugs into my mount and then into my Pegasus UPB This was the cable that iOptron in the US told me to obtain
  14. With all my iOptrons I use one these and they work perfectly: - https://www.amazon.co.uk/Ioptron-Telescope-Control-Equatorial-Ieq30pro-Length-3-2feet/dp/B07MF9H9KP/ref=sr_1_3?crid=1D6EJ9MRYJ79O&dchild=1&keywords=ioptron&qid=1619568842&rnid=1642204031&s=computers&sprefix=Ioptron%2Caps%2C159&sr=1-3
  15. Hi Nigel, welcome and please enjoy yourself here.
  16. Terry, wonderful to read through this, superb workmanship
  17. Hi Brian, it was @peter shah who introduced me to G2V and we both work on changing the duration of the subs not increasing/decreasing the number of subs. The basic concept of G2V is that you capture the correct exposures that closely match or own visual perception, I would have thought that increasing/decreasing the number of subs will not have the same affect, but I remain to be corrected. I can remember Peter banging on to me that you don't waste time capturing more of a channel than is needed. I used it exclusively on my 10" RC and now I have figures for my 10" Newt then I will use the calculations with that. I have still to do it with my other rigs, but currently they are running OSC. Ideally you should run the calculation on a regular basis and ideally on each part of the sky you are capturing from, personally I just get the calcs and use them and haven't updated since the beginning.
  18. Welcome Martin, we are a chilled relaxed forum and if we can help then ask away.
  19. Thanks Dave, I'd forgotten about its companion stars until someone posted under my image on FB: -
  20. Yep they do enhance it, Peter had a new Spyder made that he designed for my Newt, they really do work 🙂
  21. I found myself one night having just completed another target and with no moon puzzled as to what to image as I don't like to waste nights like this. So for fun I thought I would aim at Polaris, that being a star from which all my Astronomy photos start from, I had heard lots about dusty lanes being visible from dark sites and indeed my mate Peter Shah has just published one he took from a true dark site, but for me in Bortle 5/6 skies this was my best attempt. Now for anyone contemplating this, you are going to find that your equipment is not going to function as normal, I found guiding was a pain even that the star is virtually stationary, plate solving was similarly a pain where platesolve2 didn't like it but ASTP managed it. Processing was a pain as well trying to control the exposure. I'm sure many would fare better than me but as I say this was just for fun. I had to throw away about 2 hours of data as my camera has slipped and it produces tram lines for the diffraction spikes. I finally ended up with just over three hours of data, it was a bit of a bitch to process but for fun I think it has turned out OK. Taken with my Moravian G2-8300, Chroma Filters, 656 Custom 10" Newtownian Scope, iOptron 120EC Mount, QHY OAG, Ultrastar guide camera, Pegasus UPB2, all controlled via SGP pro, PHD2 and processed in PI and PS. More details here: - https://www.astrobin.com/niv51g/ Here's a little more of the Bumf: - Many people think Polaris is the sky’s brightest star. In fact, Polaris ranks only 50th in brightness. Still, Polaris is famous because the entire northern sky wheels around it. Polaris (/poʊˈlɛərɪs, pə-, -lær-/ UK: /pəˈlɑːrɪs/), designated α Ursae Minoris (Latinized to Alpha Ursae Minoris, abbreviated Alpha UMi, α UMi), commonly the North Star or Pole Star, is the brightest star of the constellation Ursa Minor. It is very close to the north celestial pole, making it the current northern pole star. The revised Hipparcos parallax gives a distance to Polaris of about 433 light-years (133 parsecs), while calculations by some other methods derive distances up to 35% closer. Polaris is a triple star system, composed of the primary star, Polaris Aa (a yellow supergiant), in orbit with a smaller companion (Polaris Ab); the pair in orbit with Polaris B (discovered in August 1779 by William Herschel). Here's an interesting article by Bruce McClure, it keeps things nice and simple: - https://earthsky.org/brightest-stars/polaris-the-present-day-north-star
  22. Welcome Richard to this forum, the skies must be beautiful where you live.
