Hi astrogadge I've copied your tutorial but seem to have a different outcome I wonder if you could help me? When I've downloaded the fits images and converted them to tiff I've opened them in photoshop placed them into the channels but there's no data or not alot in the histogram? Strange 🤔
Hi there, Firstly thanks for watching! It sounds like the files are still linear and need stretched - in photoshop I think you do this by using the 'levels' slider which is in the adjustments menu. You sould then start seeing more detail and histogram data. I use pixinsight so Im not au fait with photoshop - but I think that may be your problem? Once the image is stretched you should be able to see dtail and process. In the video I do mention stretching the data at 9:39 - but I should have emphasised this more. I hope that solves the problem!! Thanks again! Cheers, Ray.
Hi Astrogadge! I'm following this tutorial, I've downloaded the same data (I hope) and combined frames with Channel combination. But the result is awfully red. Do you have any ides why that could happen?
Hello there, can you explain which files you put in the channel combination? Remember, longest wavelength filter to the red channel, shortest to blue and the one between these to the green? Can you send me a screenshot? Cheers Ray
@@astrogadge2276 So I have hst_07515_01_wfpc2_f487n_wf, hst_07515_01_wfpc2_f502n_wf and hst_07515_01_wfpc2_f547m_wf as you've shown. I've put them 656 as red, 502 for green and 487 for blue filter. I think the problem is in the input frames. My 502 image looks odd as STF applied. It's too bright I think. How could it possible?
Thanks young man!
