Hi, I am currently using a TS CFAPO90F6 with a field flattener (540 or 1080mm focal length with a telemate x2), an OSC ASI2600MC, guiding with evoguide50ED and ASI290MM on an AM5.
I was looking for more aperture ,in visual my fever ended up with a 22inches dobsonian ;-), but I am wondering what are my alternatives including moving to a monochrome camera to improve my captures and images.
Here are 3 options, what do you think might produce the most significant improvement?
-moving to APO 110mm f6 with flattener and keep my OSC Camera?
-moving to a newtonian 150mm f4 with flattener and keep my OSC camera (I have big dobsonian F4 so collimation is not frightening me)?
-keep my APO 90mm and move to the ASI2600MM?
Thanks for your feedback and experience.
