  1. WOW there's a few in there Thanks for the link Peter I think my PixInsight trial is about to expire, I'm very impressed with it. There's some great tools and mostly unexplored by me. When processing an image I find myself mainly using Startools then loading up in PI for a couple of tools then finishing off in PS To be honest my best images have come from ST because I know it well, I'm sure PI would give a better image but I'm quite lost when straying from the few tools I use. A long focal length scope will be before PI. And I still want a CCD Nige.
  2. Nice one bobro. I also processed an image of multiple galaxys from a couple of weeks ago, have been waiting for clear skys since then. This is just 10 x 4 minutes with flat dark and bias. Seeing was bad at the time so not a great image but at a close inspection there is at least 34 distant galaxys in the image. The colours were quite bad so I went for B&W. The Virgo galaxy cluster. 80ED pro, eq3 pro, canon 1300d. Orion 50mm mini guide scope and Orion starshoot guide cam. Cheers Nige. I think there all galaxy's
  3. Thanks for the info Dave. As you have probably noticed I have only been doing AP for a year and don't really know that much I am going to upgrade the mount asap, also a CCD is on the cards eventually, both will probably within a year. I'm in no rush to get a new scope so maybe the mount should be first Thanks, this is the info I need. I thought I might be asking to much from my mount, although it would be fine for planetary imaging which is also a reason for a longer FL. Now I am going to research "/ px. I have no idea at the moment what it is.... I'm guessing pixels per something Cheers Nige.
  4. My reflector is a star discovery 150p with a nasty plastic focuser which barely stays stable with the camera at prime focus, I don't think it would cope with a barlow and dslr, but I do intend to give it a try when the persistent clouds finally part.
  5. I was thinking about the skymax 127 rather than the 150. I like to push the boundaries of my equipment ( performance wise ) my eq3 has been professionally serviced and so far has given me great guided images upto 8 minutes exposure times and I think it's worth trying a longer focal length. A better mount is on the cards for next year. Nige.
  6. Evening all. I'm looking for a scope suitable for small DSO AP, limited budget around £300. As usual I really don't know what to look for with so many different reviews and scopes available. Something that will capture the smaller galaxy's and clusters with better detail than my 150p. It needs to be around 4-5 kg as it will be used on an EQ3 Pro with a DSLR and mini guide scope setup. Am I asking for to much with a small budget. Your guidance is greatly appreciated. Nige. PS. is the skymax range good for AP.
  7. No idea, it looks like all the outlets sell with the aluminium tripod.although it specifies the stainless steel type.
  8. oops double posted
  9. Hi Dust cap, Good name I was imaging with my new 150P last year, an object at around 75 degree altitude. All was going well until my scope fell off the mount and hit the concrete, the tripod being fully extended so the scope fell around 3 feet. It bounced on the plastic primary mirror housing, the weight of the DSLR suddenly stopping as the tube hit the concrete flexed the plastic focuser. I was lucky, if it had been an expensive scope with metal mirror housing and focuser I'm sure they would have been damaged more. A quick check of the scope and camera showed no real damage other than a scuff on the plastic primary mirror housing and a little white stress mark on the focuser. I had not mounted the scope properly, a loose bolt and no slip screw on the mount. I did continue imaging. I now tighten the scope bolt very tight so it never happens again. Its the first time I have seen a telescope bounce and the quickest I have ever moved in my life Cheers from Rayleigh Nige.
  10. That's real tough luck Jimbo. Enjoy your wine at least, there will be more clear sky's for you and you know it's worth the wait. These things are sent to try us. Can you not manually track and video Jupiter. You only need 30 seconds or so to get a good stack in Registax or Autostakkert. Chin up. ☺ Nige
  11. Thank you. I use Canon EOS utility for capturing, PHD2 for guiding, Deep Sky Stacker for stacking. Startools for processing and Photoshop for polishing off. I have tried other processing software, all have different features which work better than others but always go back to StarTools which I know best. Hi Carole, thanks, That must be another Nigel I haven't been to a star party yet. There is another Nigel on here who also has the clangers as a profile picture I have only a FB page at the moment but will setup a blog soon on my website. Thank you all for your kind words. Nigel.
  12. It's been 12 months since my first image was produced from stacking multiple images. It was M 51 with my Canon 1200D, a 150P reflector on a Star discovery Alt-Az mount. I still consider myself a beginner but have a greatly improved knowledge of deep space and astrophotography. Since April last year I have probably spent close to if not over couple of thousand £'s on bits and pieces, a new refractor, a new mount, a new camera or 2, a new guidescope, new PC, lenses and the list goes on I was hooked from the first view through my 8" Dob November 2015 at Orion. I only started imaging to get a bit better look at what I could see through my scope, then I soon realised that was not enough, there was more than that available from my light polluted back garden. From the start I was totally amazed at what my cheep scope and entry level DSLR could capture. I never realised these objects could be imaged from the average back garden. I soon was self modifying my Canon 1200D which went a little bit wrong, I shorted out the main PCB when re assembling the camera. The camera was out of action. I had to go a buy the wife a new camera so I could continue imaging while I started to repair the other Now I just want stuff new CCD, new mount , couple of new scopes, back garden observatory They will all come in good time. With a ton of help from many kind people in this forum I improve little by little. If it wasn't for the No EQ DSO challenge thread I might have missed the chance completely. I have recently bought a second hand EQ3 Pro and a new Equinox 80 ED Pro refractor with a field flattener, another small step forwards for me. Auto guiding was a leap forward from the very first try 6 weeks ago, everything worked as it should, I could now take longer exposures, I could keep every sub, even setting up is quicker than my Alt-AZ mount once the initial positioning of the mount an polar alignment was done. With every bit of new equipment comes new challenges, I love a challenge and to try and solve problems. My images are a long way from CCD and observatory images but they please me no end. I have posted my 10 favourite first year images from both Alt-AZ and guided EQ3, reflector and refractor scopes, modified and non modified cameras. I always look forward to the next clear night, sometimes its a long time coming with cloud cover being the norm. I don't know why but I seem to choose expensive hobby's. Sailing is my other. If only a tracking mount for a yacht at sea existed it would be a perfect world Thanks for looking Nige.
  13. Ian. I am trying PI with the 40 day trial not quite moved completely to the dark dark side I have not tried stacking with PI yet, ( the old "I know DSS " thing ) I think on very close inspection there's a fraction less noise in the first image which is my normal stack, and a fraction more gradients around the edge in the 3rd but really not much in it , It obviously works for some but not all. If I had no dark frames I think I would just stack L-F & bias. I might try it with another image, I'm swapping cameras to the unmodified for a few images so maybe that might be different. Nige.
  14. I have finished a little experimenting with using a master bias as other options, here's my findings of 5 different stacks. Everyone's results would probably be different from mine. 1 Normal stack - Lights, proper darks, flats and bias. 2 Lights, flats & bias. 3 Lights, master bias as a dark, flats & master bias as a dark flat. 4 Lights, master bias as a dark, flats and bias. 5 Lights, master bias as a dark, flats, master bias as a dark flat & bias. Any stack that had bias stacked with a copy of the master bias I got a blank image except for number 4 where I had only the brightest stars visible after full stretch. Number 1-2 & 3 stacks all produced a good image which I think number 1 being very slightly better maybe. Number 3 stack DSS suggested not to have the black point set to 0. I tried both and setting the black point to 0 worked.. Unchecking the black point to 0 tab produced no image. I know I'm not hurting my images with darks and I can get away with no darks, but I could not better my images by using a master bias as another calibration frame. 3 images #1 L-D-F-B #2 L-F-B #3 L-MBd-F-MBdf. All background extracted and auto stretched only in PixInsight. Nige.
  15. Ian, I made several stacks. 1 Normal stack - Lights, proper darks, flats and bias. 2 Lights, flats & bias. 3 Lights, master bias as a dark, flats & master bias as a dark flat. 4 Lights, master bias as a dark, flats and bias. 5 Lights, master bias as a dark, flats, master bias as a dark flat & bias.

I tried both and setting the black point to 0 worked.. Unchecking the black point to 0 tab produced no image. This DSS cheat has not worked for me but I know I'm not hurting my images with darks and I can get away with no darks. 3 images #1 L-D-F-B #2 L-F-B #3 L-MBd-F-MBdf.
