This is first "remote" light for my system

finally got the balls up to open the roof from Sydney and image. it is only 30 mins of lum, there are a few issues that need to be addressed so there was no point getting any more.
1) i have struggled to get good flats so i will have to take some with my light box when i am down next time. you can probably see a little gradient in the image. i want to build one into the observatory so i can take good flats any time.
2) this one will probably content for the dumbest thing i have done thread ... but i cant quite reach focus. i get the closest with the clear filter but i need to add a spacer so i can get into sharp focus.
3) i am yet to run PEC on my mount which should help the tracking but it was not bad for first attempt, also i could refine the PA a bit
anyway, feedback is welcome but be gentle on me, it has been a long hall to get here
