yes, I would start with a three stripe Modell around the target.

I am once again re-thinking if it makes sense to attempt unguided imaging on my C11" EdgeHD where I have now locked down my primary mirror and upgraded to the Optec FastFocus system where focusing is done solely using the secondary mirror. This should eliminate the major mirror flop/shift issues due to moving the primary mirror. My scope is on an AP1100 in a permanent observatory but I do not have encoders. I use a ZWO ASI2600MM Pro camera (APS-C sensor) and usually use the 0.7x focal reducer. The question is: Is it even worth the effort to try building a model to go unguided imaging or is a refractor still the way to go? Guiding works ok but it can be finicky at times.
