gabs Posted March 18, 2021 Share Posted March 18, 2021 (edited) Hi all, On Tuesday the 16th I tried my first tentative to take some pics of the Orion constellation with the intention to spot the Orion Nebula. I will summarise the steps I followed and result achieved with the follow equipment : CANON EOS - CANON EF 50MM LENS - LIGHT POLLUTION FILTER - REMOTE SHUTTER 1) I took No. 12 exposures at 20 sec F5 ISO 800 ( with an interval of 2 sec each one )+ BIASFRAMES No.12 same exposure, temperature etc + DARK FRAME same setting and FLAT FRAME using my tablet screen; 2) I stacked the exposures into DeepSky Stacker . I got one frame saved saved as TIF ( IMG_3899 ) ; 3) on GIMP I opened the file as per screenshot attached (154028 ). Is the histogram correct or should I expect something better ? 4) When I start to adjust the colour levels then they start to appear the stars however there are tiny some red dots ( screenshot No. 155454 ) , why ? 5) when I zoom in in area where is should expect to see something , the result is what you can see in the last screenshot ( 165644 ). Please let me know what I did wrong and what right , if there is something correct ! Thanks in advance Edited March 18, 2021 by gabs Quote Link to comment Share on other sites More sharing options...
