Greetings all. With the Covid19 epidemic and a sudden amount of 'free time', I'm trying to get back acquainted with my telescope and attempts at imaging. I have a CPC-800 XLT scope and I have an ST 8300M with CFW5. I also have a TS Optics Off-axis Guider (details https://www.teleskop-express.de/sho...-Axis-Guider-TSOAG9---Baulaenge-nur-9-mm.html). What is the recommendation for spacers before/after the TSOAG to give me something that is in focus? Any assistance is appreciated.
