This is really good and comes out very well. I haven't managed something that good with a simple lens and such exposure times.

One thing to consider is doing a longer exposure on each sub. Did you limit to 1.3s because of lack of tracking? If you HEQ has a motor, you may try to do a polar alignment (it doesn't have to be perfect) and extend to 30 sec subs at 1600 ISO. you should good really good results out of it and plenty of colors in the nebula.

nice work! poor weather has a silver lining, which is many astronomers will do great DIY projects. looking forward to seeing the results
