Re: ASI1600MM + 2" EFW + M68 OAG < 55mm back focus possible?

Hello,

Thanks for the reply.

1600MMPro(17.5mm)

The 1600MM has only 6mm of backfocus, and I believe it can connect directly to the EFW using the M42 to M54 adapter supplied with the EFW. Is that not correct?

The 2" EFW has an M54 female thread on the camera side, yes?

Cheers,

Ross

Re: ASI294mc to Rokinon 14mm setup problems

If the stars are lines pointing away from the center, you’re not close enough

No, if your stars point into (or away from) the center, you are too close. You need to add spacing.

If you stars circle around the centre, you are too far away. You need to remove spacing.

Re: ASI1600MM + 2" EFW + M68 OAG < 55mm back focus possible?

Replying to myself, but I'm sure there will be others using 1600MMs and wishing to do the "slow upgrade" to 2 inch filters like I am, so I hope this post is useful. This question is holding up a roughly $2k order to ZWO; I can't really proceed with the order unless I know this is going to work. Afte...

ASI1600MM + 2" EFW + M68 OAG < 55mm back focus possible?

Hello, I'm preparing for the move to full frame. I've ordered a set of Chroma 2" filters and am about to order the ZWO 2" large filter wheel and M68 OAG. Until I have the funds to purchase the ASI6200 mono I wish to use my 1600mm Pro. The imaging train is to be used with a reducer that has the stand...

Re: I miss a mono camera with a medium chip

I would also like to add my voice to requests for an APS-C or APS-H-sized mono cooled camera. I'm sure it would be a best seller to many like myself who wish to upgrade their 1600MM.

Re: ASI120MM mini and PhD2 = no 16 bit

Hello Chad, Yes, the camera is working well using 8-bit in PhD2 (ASI driver and ZWO driver) on two separate PCs. The camera does not work in 16-bit mode on both those PCs. The camera works well in both 8 and 16 bit mode when using FireCapture and SharpCap, so it would appear that the problem is not ...

ASI120MM mini and PhD2 = no 16 bit

Hello Chad and crew, I've read similar reports regarding this apparent incompatibility that appears to be still unresolved, so thought it wise to add my experience. I purchased my ASI120MM mini (mono) back in August 2018. It will connect to and display images in SharpCap without problem, both 8-bit ...
