Hello Pippo,

All fixed now!

I've installed 2.4.2.8 x64 and x64 and can get the camera working in Firecapture and PHD (PHD requires you to pick WDM camera).

Does anyone have any experience getting PHD to work, i.e. exposure times etc? Is it better to use the ASCOM drivers here? http://pludov.free.fr/ascom_firefly.html ? I'm not familiar with the software and would be grateful of any assistance, Firecapture on the other hand seems pretty straight forward!

I have 2 cameras and plan to use 1 for guiding and 1 for planetary...

Update: It seems the ASCOM drivers do not work correctly under Windows x64. I have FlyCapture x32 and x64 installed, but when trying to connect to the camera using ASCOM diagnostics I get an error:

Connect Failed...Could not load file or assembly 'FlyCapture2Managed_v100, Version=2.3.3.18, Culture=neutral, PublicKeyToken=76c6583b4a4585f4' or one of its dependencies. The system cannot find the file specified.

Can anyone do this successfully?

Mark

I almost pulled the trigger on this as a mono imager for use with my coronado pst, however after reading Piotr's review, it was evident that this camera is prone to newton's rings interference. My current Orion SSAG autoguider (QHY-5) has the same issue with newton's rings, and no amount of twisting the camera eliminates them and they are present no matter what power I use. I assumed it was due to the IR cut filter.

My question is, after removing the lens on the firefly that has the IR cut filter, is the newton rings interference still present and if so, does anyone know a viable workaround? Money is tight right now and I can't get the imager I want and this would be a great temporary solution while I save for an AS120MM or similar.

thanks,

It's related to Micron/Aptina sensors. Firefly and QHY5 use them. The rings are caused by the sensor cover glass which can't be removed. ASI is also Micron based... but those cover-based artifacts don't show up in every sensor of given type.

Thanks for the clarification, it looks like I will pass on that one for the time being. I know the rings are on the SSAG and thusly will be on the firefly as well then.

thank you!
Andy

Jupiter + Io's Shadow + Io, from Paris with the Intes 703 at f/26 and the Firefly on the 18th of Feb 2013:

This without IR-cut filter at at 20:31 UT (21:31 local time).

The image with IR-cut filter is more resolved (the Airy disk is bigger in the IR) and with the IR-cut filter the red spot exhibits more contrast (it is darker).

Yesterday the turbulence was minimal so I tried to push the focal length to f/35 (with a televue barlow 3x, Intes 703 mak 7", IRcutoff filter and obviously the Firefly MV).


Here is the result without rescaling:

And here the same rescaled at 80% to compare with the f/26 images.
