Experimented with both camera and newly received half inch extender.
Focus:
ASI 290 + 1’’ ring + 0.5’’ ring + FR => could only achieved focus by removing one of the focuser extension rings [focuser at 1.3 cm] [sensor to FR lens ~48 mm]
ASI 385 + nose piece + 0.5’’ ring + FR => could not achieve focus
ASI 385 + nose piece + FR => could only achieved focus by removing both of the focuser extension rings [focuser at 1.8 cm] [sensor to FR lens 42 mm]
Notes on ASI385:
Larger field of view
Could stack with more ease (not sure about this one)
Seems to pick up less details at the same exposure, maybe the higher f-stop(without processing?)
Not showing colors for chosen targets (without processing?)
Fit seems less secure
Observations:
Could not find/see IC444 (reflection Nebula) - Gemini
M41 (Little Beehive Cluster) - Canis Major
M81 (Bode’s Galaxy) - Ursa Major
M82 (Cigar Galaxy) - Ursa Major
