I recently bought the Askar C2 (SII/ OIII) Dual Band filter with the intention of seeing what results I could get by combining the the data from this with that from the Optolong L eXtreme (Ha/Oiii) Dual band filter, hopefully to produce a true Hubble SHO pallate with an OSC. The C2 filter has a much wider bandwidth than its more expensive version - the D2 - so I was interested to see how it performed.
To test it out I imaged the Rosette Nebula in monoceros.
Find out how I got on!!
My usual disclaimer: As with all my videos, I don't claim to be an 'authority' on the subject in question, but hope my understanding and personal experience of it are helpful to others, as other peoples have been to me. I should also make it clear that I have no affiliation, financial or otherwise, to any of the products or vendors I may refer to.
Thanks for watching!
