I figured it out eventually, for those looking the Horizons use a similar focusser to William optics with the grub screws accessed though the a grub screw sealed hole. 2 screws set at 90 degrees

Came across this whilst looking at getting an EAF on my 102, could you post a picture of how you got it fitted? Ta

Not all as we all have crappy spoiled subs so I ditch those, keep the best so that you can add to them later on. You can use them for pictures with data captured on different seasons, or make mosaics with adjacent framed subs in the future

I tend to take raw and jpegs, then using the jpegs as proofs get rid of poor raw files. Organisationally I file them according to target. You could always have a central HDD connected to your router as a data storage hub rather than using online storage all the time

Also use raw files instead of jpeg

I recommend seeing them in person if you can, I've got the vx 8 and it's a formidable beast for a first scope. But if you know what you're getting into it's a great telescope, just know that your expenditure won't stop with just the telescope and mount. There are a multitude of extras and aids to consider as well as a wide array of eyepieces. First will be a decent power supply, mains if your close to your house or a power tank if you plan on going out and about

I'm no expert, having only recently got into stacking properly myself but from my limited playing with dss, average on the lot seems to be best

I did this the other day, you need to change your stacking settings from kappa-sigma to average and that will get rid of your hollow stars
