Popular Post +Graham Posted September 7, 2020 Popular Post Share Posted September 7, 2020 (edited) Had another unexpected session tonight so I decided to go back to some narrow band. Revisited and old favorite in the Wizard Neb. Was hoping for another all nighter but alas the clouds rolled in again. Gt81 QSI 683 6 subs at 600 seconds in HA 6 subs at 600 seconds in OIII 6 subs at 600 seconds in SII Captured and stacked in Maxim. Beaten into submission in PS 6. Been a long time since I did a Hubble process I had a devil of a job to remember how to do it. Of course it could just be old age 😅 Edited September 7, 2020 by Graham +RonC, Bottletopburly, BAZ and 3 others 6 Link to comment Share on other sites More sharing options...

+Graham Posted September 7, 2020 Author Share Posted September 7, 2020 (edited) Had another look at this with fresh eyes. Still doesn't look quite right 😕 Edited September 7, 2020 by Graham +seven_legs and +RonC 2 Link to comment Share on other sites More sharing options...
+Graham Posted September 7, 2020 Author Share Posted September 7, 2020 If anyone fancies a go at processing this data here is the link. https://www.dropbox.com/sh/9tbhwx68k9i2087/AAALy4Y6xjdJ-l7JTwqiPlVla?dl=0 Be interesting to see what you come up with.

Bottletopburly Posted September 7, 2020 Share Posted September 7, 2020 (edited) can stack separate data in DSS but when i load up in startools stars not aligned ie how can i align the three stacks together so stars match or do you have a single fits file graham of all three combined then i can pull channels separately using startools ? Looks nice too though seem to have some walking noise anomally obviously my stacking is rubbish and no colour trying to stack in dss Edited September 7, 2020 by Bottletopburly Link to comment Share on other sites More sharing options...
+Graham Posted September 7, 2020 Author Share Posted September 7, 2020 (edited) I do that in Photoshop David as separate layers. Each layer is either -- HA , OIII or SII and each layer is a different colour -- R, G or B You can move each layer about independently of the others to align the images. Once aligned and colour adjusted the layers are merged to create the final colour image. Never used Star tools.

Bottletopburly Posted September 7, 2020 Share Posted September 7, 2020 i found how to do in dss but because the files are showing slightly different sizes they wont stack as three ,will have another look Link to comment Share on other sites More sharing options...
+Graham Posted September 7, 2020 Author Share Posted September 7, 2020 That is the beauty of Photoshop. you can align the 3 layers then crop the 3 simultaneously to the same size Link to comment Share on other sites More sharing options...
Bottletopburly Posted September 7, 2020 Share Posted September 7, 2020 working on it it was //is a dss issue Link to comment Share on other sites More sharing options...
Clive Posted September 7, 2020 Share Posted September 7, 2020 I had no problem stacking them in DSS, I just chose one Ha image to be the reference frame when individually stacking the images for each filter. The problem I've got is all 3 images are virtually identical so applying them to the RGB layers just gives a grey image (just a hint of colour on the satellite trail on one of the images).

+Graham Posted September 7, 2020 Author Share Posted September 7, 2020 (edited) I stack in Maxim so no alignment issues as it does it automatically That is exactly the issue I had Clive. very little to choose from the different channels.

Clive Posted September 7, 2020 Share Posted September 7, 2020 Yes, I did wonder if I was stacking the same images by mistake so I tried subracting the OIII from the Ha and the SII from the Ha and apart from a few rings caused by slighty different sized stars in the 3 images, the result was a black image. You may as well just use the Ha image in each colour channel 😕! Link to comment Share on other sites More sharing options...
+Graham Posted September 7, 2020 Author Share Posted September 7, 2020 (edited) Interesting to hear Clive. Going to check the camera filter wheel settings on Maxim tomorrow It did strike me as strange with the little difference in the subs as they came in but trusted the fact that Maxim was telling me the filters were changing.

Clive Posted September 7, 2020 Share Posted September 7, 2020 That thought had occured to me, the images seem just too identical. Link to comment Share on other sites More sharing options...
+Graham Posted September 7, 2020 Author Share Posted September 7, 2020 Got me worried now Going to go and set the camera up and test it Link to comment Share on other sites More sharing options...
+Graham Posted September 7, 2020 Author Share Posted September 7, 2020 Hold the front page. Capture settings were not changing the filter wheel. Clive you are spot on all 18 subs are in HA. Glad I put the data up for you folks to have a play with or I might not have found it. Nice piece of detective work Clive 👌 Link to comment Share on other sites More sharing options...
Clive Posted September 7, 2020 Share Posted September 7, 2020 So all you need now is 18 more subs in each of the other 2 filters 😊 +Graham 1 Link to comment Share on other sites More sharing options...
+Graham Posted September 7, 2020 Author Share Posted September 7, 2020 Starting work on that right now 😉 Link to comment Share on other sites More sharing options...
Clive Posted September 7, 2020 Share Posted September 7, 2020 You got clear a sky then? 100% cloud here ☁☁☁. Link to comment Share on other sites More sharing options...
+Graham Posted September 7, 2020 Author Share Posted September 7, 2020 Patchy cloud but sadly too much for 600 second subs. Will have to pick this up later. Thanks Clive for solving this one. No wonder I had such a hard time processing it to Hubble 😅 Revised image Wizard Neb in HA 😅 😂 😂 +seven_legs and Clive 2 Link to comment Share on other sites More sharing options...
+Graham Posted September 7, 2020 Author Share Posted September 7, 2020 Fault found. The filter selection settings had changed so all filters were set as HA. The file prefix for each filter however had not changed so in the capture window it was telling me that the file prefixes were changing but sadly the filters were not. That's a new one on me as it has never happened before when I was using the old XP computer. Will have to keep an eye on that in the future.
