I took this on the 2nd night of my first ever trip to the Leyburn dark sky site in SE Qld, after chasing low lying Messier objects. The wind was much kinder on the Sunday night fortunately so little loss of subs and decent tracking. I'd like to say I've tried to be creative with framing, but actually I botched half the red frames and lost about 1/5 of the bottom of the image I'd planned to get
This is LRGB 15:12:12:12, all 3 mins subs, unbinned Lum, RGB all binnedx2, taken with QHY9 through 8" Newt/MPCC.
I'd hoped to get some Ha recently, but camera problems have prevented so far. Still, I was pleasantly surprised to get this from 30mins of data.

A few artifacts in there Rob, but it's alright seeing what you lost
Cheers
Coming along well for 30 mins,more time plus the Ha data will solid out the effort.
Looking forward to having a go at the horse head in Ha myself soon,
Thanks guys. It was quite a lift to dig this one out of the vault
Clive, I've had a few episodes of bright lines with the 9 over recent months. Theo has been bending over backwards to assist and replaced a board for me. I honestly thought it was licked until last weekend. I'm going to take a good hard look at all my connections and power supply. This is the sort of thing I've seen below. On Sat I could still see a starfield behind it, but I don't think my processing is up to removing this alas!
I see your issue, if it's intermittent its possible it's a connection type issue. But yeah, you cant do much with that through the middlenof the image.
My experience with Theo has been the same as yours, he is most helpful and willing to help regardless, so it's nice to have the backup.
Best of luck...... BTW couple of things, I like the framing, and one of your spider vanes may have a slight bend/twist in it, I used to get a similar effect when I had a newt and that was the cause of the differing spikes.

Yes, I was thinking same thing re the vanes too. This data is coming up 6 months old now and I'm usually more careful with the 2ndary and vanes setup. In fact Adam had a thread here some time ago where the effects of mis-aligned vanes was clearly illustrated.
Not a bad crack of the whip at all there Rob, with the spider vanes i find that using a metal ruler or such layed across soon shows up any miss aligned vanes I use it when I have done a complete pull down!
Look forward to seeing some images pour out of that 200mm mirror once the qhy9 gets back!
It's probably just a sign of how much I've still got to learn Brendan, but it's funny how you work on a number of objects that fail to come to life due to lack of data (which you sort of expect, but it still seems a shame) then all of a sudden some forgotten data on a faint object you think will be rubbish comes out half decent!
Good tip re the ruler - I'll have to include this in my remote checklist after transporting the scope to a star-party.
Mate when you stop learning your dead! Its when you have little things that keep bugging you and you go and find out whats going on to fix them is when you really start learning the good stuff! My old 254 newt is a classic example of that and as such its getting nearly to the point that i cant improve it any further! Just a few more things and shes completed.
As for data. its always the way, did a bit of work a little while ago with the 254 and a SBIG 402ME which has a tiny sensor, if you look in my gallery under galaxies you will see the effort there. amazing detail for a sub 1MP camera! and then sometimes you get 4hrs worth of data that end up looking like spew.
Im hoping to get under the stars at the end of the month to let the newt do its thing now i have all the correct spacers for the MPCC QHY9 and everything is tuned to within a hair of a bees..... We might have to compare our HH data!
