Any possibility of a 2" filter wheel and filters ? I'm using a 36mm sensor so need the clearance .

Just an idea but I would buy a 2" filter wheel now just so I don't buy the same filters twice down the road. :)

I think so. Whatever the standard 2” interface is. I noticed the 2” filterwheel on a video of your table at a conference posted on FB. I think if you will eventually release an APS-C sized or larger mono camera one day then coming out with the 2” filterwheel soon will make it cheaper in the long run. I want to purchase Baader narrowband filters one day but would rather just get the 2” versions. Just a thought, but for my asi1600mm a 2” filter would more ideal for less then f6.

Keep up the awesome work. I look forward to receiving my asi071-pro!

I would love to be a tester but I don't have enough 2" filters to fill her up probably. I would use the 1600MM or my 071-Pro. If there was a 2" EFW available I would probably end up buying it so that I could start buying more 2" filters, eg RGB-H etc.

As of now, the largest monochrome chip is the ASI1600, right? I think the standard size for 2" filters is 50mm round unmounted filters. That is what I have. I know it would be very big, but a 10-position 50mm filter wheel would be great. Or at least being able to use unmounted 50mm filters. That would allow for LRGB, Narrowband (HA, SII, OIII) as well as a couple of astrometric (BVR) filters in a single carousel.

Secondly, not related to a 2" wheel, but I have the 7 position 36mm wheel, and was wondering if you could just purchase an additional carousel for filters, so you don't have to remove the individual filters if you want to use others? Those mounting screws are very small. and for those with a a lot of filters, it would be a lot easier to swap them out that way.
