IC1805: Combined image – Take 1


Using GIMP to process images. I have not yet become skilled in gradient removal but I am improving somewhat. Here are some rough Ha images of IC1805 combined with images taken with the Optolong L-Pro filter: my first attempt at stacking different images with at various wavelengths – I do see the advantage of this; however primitive my process is now. Some of these images are sharpened; but I do prefer the un-sharpened images. BTW: Shooting with Canon T7 DSLR: 180sec, 1600ISO. Telescope: Meade LXD75 SN-10.

So what’s next? I will continue to learn with this object IC1805. My next exposures will have a lower ISO setting to bring down the brightness that is causing the vignette – 180 or 300 seconds with ISO 800 (using the Optolong L-Pro), and the same with the Ha. Anything higher than ISO 800 is just too bright with the light pollution at my location. I have been considering trying out the Optolong L-enhance filter: https://youtu.be/b1yVLG1q6Sc
