Hi, I bought the "STX-Ultimate" package in March of 2019. I chose the SBIG "50mm square LRGB filter set" and the "50mm Square Narrowband set of 3 filters Ha, SII , OIII" for the filters. Pixinsight has some very useful tools for processing data, which want to know what brand those filters are; they don't have "SBIG" as an option. I would appreciate knowing what those filters are, so I can use these tools optimally. Thanks. Mark
We've used a variety of filter suppliers over the years, including Custom Scientific, Baader, and Optolong. I'm not sure which you have.
Unfortunately prior to implementation of our ISO9001:2015 QA system in 2020, we didn't document parts batch numbers so I can't be 100% certain. That said, I looked at the filter purchase order history in our ERP system... judging by your purchase date, I'm fairly certain you got Baader filters.
Here's another way to check - of you kept the original filter boxes: - Baader filters often came in a plastic box that slid apart (like a drawer) or flipped down and had an multi-colored insert paper. - Customer Scientific had a clear plastic box and often a yellowish paper insert. - Sometimes there is a marking or label on the blackened edge. If not edge blackened, then it may an early Optolong. - If in a white paper box with a two part, then it may be an Optolong or another OEM.
Thanks! I doubt the boxes still exist. I image remotely, and someone else set up my stuff in 2019. I moved it in 2020, but I did not get any boxes when I moved it. But I thank Doug for his response!
