At the 11:45 mark I mention crop size sensor while also mentioning the ASI294MC and ASI1600MC. I meant to say Micro 4/3 sensor.. not crop. The 1.25" filter is not big enough for a crop size sensor.
Interesting video James! This looks like a great filter for OSC, I have the Optolong L Extreme and the L Pro, love them, but as you say, the LExtreme is only 7nm, so the new 3nm will be much better! Good idea with the filter wheel too! Clear skies👍
Excellent video James. I have used the ZWO 5x2" filter wheel with my Esprit/ASI2600MC since day one (UV/IR cut, L-Pro & L-Extreme filters). Even though the ASI2600MC has a UV/IR cut window I used a filter as well to keep everything parfocal (I have my backfocus set to 55.7mm to account for the filters). I am now imaging from a bortle 3/4 zone (well, In would be if the weather would clear up!) so will be retiring the L-Pro filter going forward.
There are SII/OIII dual narrowband filters nowadays. I'm not sure if they come in 1,25" versions but it makes SHO imaging with OSC much more practical. Especially with a filter wheel.
I have the 533MC and love my EFW. Just ordered the 2 inch version simply to have access to a larger variety of filters. I use a CLS or quad band filter and then use a pure Ha filter and then combine the results. It really enhances the overall image.
yup ... you're right 👍 flats are needed on most of my gear ... even the Samyang 135 ... I kind of hate the fact that o cannot rotate the whole scope to better frame objects with my C11 ... I can with the 115/800 .... cannot with the Samyang as I have it now ... maybe I'll pair it with a filter drawer and the 585 and then will be able to do that. PS. a filter wheel is a good place to store all those filters and have em handy!
Using a filter wheel with and OSC makes sense especially with the filter options you are using. Filter draws are ok but they do often leak light in and also introduce dust every time you change filters. (been away from easy internet access so I'm just catching up on videos).

making life easier with a filter Wheel and a OSC. can't wait to see what you capture with the L-Ultimate. CS
Thanks Jason!
That's an interesting use of a wheel James I can certainly see the switching BB/NB advantage here part way thru the night. CS :)
Thanks Ollie! CS!

Thanks Pete! Grats on the bortle 3/4 upgrade. :)

I Know that Askar has one. I also know about the one IDAS has, but I heard they stopped selling theirs.

Nice! Even if I ran just two filters.. I'd keep the filter wheel :)

Yes.. a filter wheel is a great place to store extra filters, as long as you don't forget you put them in there! Got the T-shirt on that :)

Thanks for stopping by Logan! Always good to hear from you :)
The L-Ultimate is one of the best investments I've made in this hobby.
Good to hear :)
