Hi Sharkbite,
Great efforts there. Well done.
I've been there too on an alt-az mount. First question I'll ask is is your LX mounted on a wedge so you can polar align it ? If not that would be a suggestion. Genuine wedges though are astronomically priced ( pun intended ). The only solution without spending money would be to get creative and make your own ( this is said without knowing how handy you are with tools ). This is going to give you the ability to take longer subs without star trailing and prevent feild rotation.
If you can't/don't want to go down that avenue and just want to work with exactly what you have already. My best suggestion to you would be to take at least 10 times as many subs. Aim for the 2-300 mark. This will increase the signal to noise ratio and you'll find you'll be able to stretch the image further to extract more faint detail before horribly introducing noise.
Certainly a great start there. Well done
