  1. Thanks for the comments and interest , the rig is now sold
  2. Sorry not splitting down to smaller items would only consider a 50/50 type split at this point
  3. Hi sorrowfully I have decided it is time to sell my rig as it is not getting used due to lack of time and work commitments and it is best that someone gets good use out of it rather than it sitting in my cupboard I am selling at a very good price as it is collection only (skegness area) and I will be moving house in a few months so want a quick sale. £2200 for the job lot To list the main items; 1. Skywatcher evostar 80 ED DS pro and aluminium case 2. Skywatcher evostar 80 ED DS pro with baader steeltrack focuser and modded with a skywatcher autofocuser that also comes with a control box(one of Dions) that enables it to be connected to a pc 3. Atik 460 EX mono camera 3b. skywatcher focal reducer x0.85 4. Atik EFW2 (electronic filter wheel 2) this comes with the 9x1.25" mounted carousel 5. complete set of baader LRGB filters as well as a set of narrowband S,O and 7nm hydogen alpha filters 6. NEQ6 pro synscan goto equatorial mount belt modded and wedge modded 7. altair astro pier with mounting puck and skywatcher pier 8. icron usb 2 ranger 2304 ( enables connection of devices over cat cables) plus startech 7 port usb hub 9. Hitech astro dew strips x 4 and control unit 10. QHY5 mono guide camera 11. flat panel 12. plenty of other stuff such as telrad finder, skywatcher finder scope, batinov mask, barlow lens couple of eye pieces laser collimator, cheshire collimator various extensions dovetail bars etc. Custom attachments to get the correct spacing for the focal reducer x 2 there is plenty of other bits and pieces and considering the atik camera alone retails at over £2000 then all this has got to be a real bargain P.S I have receipts for pretty much everything which can be viewed upon collection IF YOU ARE INTERESTED PLEASE PM ME i will be selling on a first come first serve basis
  4. That's a fantastic shot of these two Barry
  5. Yes nothing on the oculus forum (yet) about this update causing issues apparantly a common cause for blackscreen is the riftdisplay. Inf driver being blocked or uninstalled . However, there are other causes for black screens. The most popular one has to do with the RiftDisplay.inf driver being blocked or uninstalled somehow. I have instructions to reinstall it earlier in this thread. And there could be other reasons too. In any case, if you experience a black screen, please submit a bug report in the Help Center of the Oculus app. It's in the lower left corner, then click Provide Feedback. Thanks.
  6. Hi Ray I have just done this update astro gear ok and so is the Oculus
  7. That is absolutely fantastic help Alan thanks a lot. There are adjusters on the baader focuser which I can try but first I will do the check to see if it is likely focuser droop. Do the ccd inspector results show if the spacing needs to be increased or decreased or can this not be elucidated from the results
  8. Hi for a while I have been getting elongated stars on my images. Given are skies it has taken a while to run through various tests in an attempt to narrow down the cause. Polar alignment is fine it has been drift aligned and verified as good with alignmaster. spacing may not be perfect but i have tried adjusting it from 55mm to 56.4mm in 0.3mm increments using steel spacers bought specifically for the job. Little if any difference noticed Guiding graphs have been excellent also. Not field rotation as the stars are like this after only 20sec exposure times. So i thought I would look at tilt as being the probable cause. I rotated the camera and the elongated stars shifted so the camera sensor can be ruled out. I checked the focuser tube using a laser collimator and that appears to be as good as possible. Maybe the weight of the camera and filter wheel are causing some droop on the focuser? The camera is screwed to the filter wheel which in turn is screwed to the custom built adapter this is screwed to the reducer which is screwed to the adapter from flo which is push fitted into the baader steeltrack focuser (not the diamond version so I had no choise in this). The image below is what I am getting now the top two corners are ok (not perfect but acceptable) the bottom two are showing the elongated stars especially the bottom right corner. I downloaded the trial version of ccd inspector and loaded 12 images into it then produced a curvature map and 3d plot of the images however I am not to sure how to interpret the results. Any help is much appreciated and maybe someone experianced with ccd inspector could help explain what the graphs show thanks in advance
  9. I used to have never ending problems with many different USB hubs until I got a startech powered hub which cost a fair bit more than other hubs but was certainly worth the extra money. Not had any problems with it. Price Was about £50 This is the one I use although shop around you will find a lot cheaper price for it than this link https://www.google.co.uk/url?sa=t&source=web&rct=j&url=https://www.startech.com/uk/m/Cards-Adapters/USB-2/Hub/Mountable-Rugged-Industrial-7-Port-USB-Hub~ST7200USBM&ved=2ahUKEwj_gsibirvaAhVDLsAKHTY0CmYQFjACegQICBAB&usg=AOvVaw3vsZH7P77eT0bvqqagbw1R
  10. Hi yes it was 13x600secs per filter Ha, O111 And S11. The work flow was the same as I used in this post
  11. Hi with the skies so bad at the moment I decided to reprocess this one. As I recently had a fair bit of help from Barry Wilson (thanks again Barry) with another one of my narrowband images I applied this workflow to this one and I think it is a huge improvement from the original. New processed one top the poor original bottom
  12. Fantastic shot lovely detail and superb colours
  13. Fantastic image so much detail, the dark surrounding area of the nebulosity is truly superb well done
  14. Thanks Barry your help and time has been very much appreciated. I feel that i have learnt a huge amount from your help here, which really shows in the finished image, wow! what a difference. I have copied and pasted your advice from this post into a document as my blueprint for future processing in narrowband. I believe large parts of the workflow could be transferred to RGB or HaRGB images also. Once again Barry thank you very much.
  15. Hi Barry I use noiseware (imagenomic) which I have as a plug in for PS it is an excellent bit of software that allows me to reduce the noise in luminance, chrominance or both giving slider controls for both adjustments. It also allows for me to set the amount of noise present for it to deal with. I have had a go with this and posted the result below to see what you think. Can reduce it further or less but I felt this was about right.
  16. Thanks Barry. Yes know what you mean but just the weather here as not been able to get into work due to road closures there is just no way in,even the boss couldn't get in today.
  17. Amazing difference. Makes me realise that I don’t understand about 90% of it though. Thanks guys getting the best out of this data is all down to Barry who has given excellent guidance regarding the processing
  18. Hi Barry I tried some gentle star reduction using a few iterations of Martin B technique using the minimum filter on a star mask and then edit fade in PS. How does it look to you better or can you see any artefacts such as dark halos surrounding the stars
  19. Hi Barry I used the DBE method to help balance the background colour and find that this has done an excellent job. Again I will await your input for the next step
  20. Pleased to see others are benefiting from this post as they are very useful hints and tips from Barry which really help you get the best from your hard earned data. That is another interesting tip regarding the magenta stars will have a look at that thanks. Ok below is the result of using Alistairs scnr on an inverted image to reduce the magenta on the stars, looks like its done a good job nice tip.
  21. OK Barry will try that tomorrow. I didn't realise you could use DBE in the non-linear stage. Out braving the weather walking the dog now
