Polar Alignment and live stacking with one DSLR (EOS R + 70-200mm lens)
Posted: Thu Apr 01, 2021 6:53 am
I am a novice in the astro-photography, so please consider it^^
Interested in planets, nebula
Is it possible to do both polar alignment and live stacking with one DSLR (EOS R + 70-200mm f/4 lens)
What do I have to do for the configuration or execution sequence?
My equipments:
- Smart EQ pro
- Canon EOS R
- Canon 70-200mm, 100-400mm f/4 L lenses
- SharpCap pro 3.2
ZWO ASI120MM-mimi + 30mm guide scope:
- During the test, CCD wasn't recognized suddenly in Camera tab of Sharpcap pro 3.2
As of now, I am working on it to solve the problem with ZWO. This is why I got this question.
After recent installation of ASCOM platform and DSLR driver, EOS R is successfully recognized.
But I am wondering,
-> EOS R (full frame) + 70-200mm combination gives a maximum 200mm focal length
-> ZWO ASI120MM-mimi (1/3" sensor size) + 30mm combination
gives about correspondingly 400mm focal length because of small sensor size which guider lens seems narrower than main photography lens
am I right?
Is it normal? I thought a guider scope will have wider scope which means shorter focal length.
Please advise me on anything to know^^
Thanks in adv.
