Tech@ZWO If so, can we use narrow-band filter under Solar. Lunar, and Planetary modes?
Nasa-HSIA No,you can't use narrow-band filter under Solar
Tech@ZWO Why? It is quite interesting if we can use narrow-band filter here and Solar filter together.
Tech@ZWO it is our understanding that there is always a built in filter in the optical path no matter what is being imaged and in what mode. There are 3 built in filters (dark, UV/IR and LP) by default the UV/IR is what’s in the path. Can you please add a request to your development team to provide the user the ability to change this internal filter to the LP filter during other imaging modes like solar and lunar especially solar much like it’s already available for Deep Sky. The filter is there… why not just allow it to be used if the user wants to use it
Nasa-HSIA and this is the crux of my question. Thank you for understanding. ZWO? Can a request for activating the LP filter during solar mode be added to the SeeStar app[](https://)
With regard to imaging the sun apart from a solar filter, why would you want or need to use an PL filter when solar imaging ?
The-Patrician From filter curve, you can see H-alpha line in the filter range. We just want to try if some structures on the Solar surface can be detected or not.
Nasa-HSIA Impossible. Way too wide. You need <1 Angstrom passband to see any details in chromosphere.
Unless the Ha line you are looking at is around 675Nm if memory serves then you would not be able to observe the Chromosphere, apart from all of the additional filtration required, such as an ERF.
Lilo Have you try to image Solar surface by using such filter before? I studied astronomy more than 30 years. Astronomy taught me that anything is possible.
Nasa-HSIA 20nm filter gives almost nothing for the Sun. But if you wish, there is always an option to put 2" filter in front of seestar's optics. Easy.
Glabella Ok,I will record to our team,thanks
