ToupTek SkyEye62AM - Sony IMX455 Sensor v4 - settings
Posted: Sun Mar 24, 2024 11:04 am
Hi Robin, hi forum,
for my Touptek SkyEye62AM (Noctutec MILAN) with the sensor v4 am trying to get data for best settings (deep sky).
As already discussed in earlier threads the ToupTek has 2 settings (LCG / HCG) which I´d like to test separately.
When choosing the ASCOM driver SharpCap crashes. Taking the native driver one gets mixed data as you described (auto switch).
ToupTek has published sensor data (of the previous version of the sensor) which show the difference in read noise:
There are mainly two situations, as Stathis wrote in another thread:
- aiming for high dynamic range
- aiming for low noise (faint signals)
I image with APT and have to set either LCG or HCG (no auto switch); my exposures are 240 - 300 sec; 3 nm NB filters.
My data attached, made with a L filter. Until now I couldn´t test the sky brightness due to the bad weather.
Interpreting Touptek´s graphs I´d take LCG mode in both situations due to the almost equal dynamic range but the better read noise (?)
Do you have any suggestions concerning the settings?
thanks, Peter
