The performance (in terms of available utitilies) of IC Cap. is much better than SharpCap. However the resource rerquirement of SharpCap is much less than IC Cap.kingyo 寫:
其實想問下,
1) Sharp Cap係咪真係比IC Cap. 好用? 有咩唔同?
2) DBK21AU618 比DBK21AU04 既整體Performance 係咪真係好D??我想知既係....Cap的影像好D定係只係後期處理時可以處理得D?

My telescope is robotic and is being manuvered from my home through internet, SharpCap is the only choice for planet shooting.
FireCap is also a good chopice but seems not handy and stable enough for robotic application (cannot accept multiple cameras)
The quality of the final photo does not depend on the capturing software. Image process software (such as Registax) may help a little but quality of final product mainly determined by aperture of telescope, sky stability, types of camera and sky transparency - i.e. the external factors.
If external factors are non-ideal, capturing and image processing software are only of little help.

DBK21AU618 is much better than DBK21AU04, due to the lower noise of the 618 CCD and its higher sensitivity.
Again I would like to stress that it's the raw data from teh camera that determines the image quality, image process could help only little, if the raw data is non-ideal.
