ASI 120MM or 130MM?

skywatcher

hello,

I have a ASI 120MM , which works perfectly, I plan to change it to a ASI 130MM for more field with my Lunt LS 35 H-Alpha and Kepler with my 100/500, I will not need to make mosaic for the entire solar disk at these focal lengths, with ASI 120MM, the focus is properly on the Lunt LS 35 while returning the maximum helical focuser, but I'm afraid that with the ASI 130MM, the focus will no longer take, the distance from the sensor thread on ASI 120MM is given to 12.5mm on some Mechanical Drawing and sometimes 14mm, what is right?

this is the same value for the ASI 130MM ?

ASI 130MM is sold without the wide field 2.1mm lens, where can we buy it and what is its price?

ASI 130MM has a protective filter in front of the sensor?

we can unscrew?

all 12.5mm distance from the sensor

the sensor on ASI130MM is very old, so we choose to stop production

there will come new camera with biger sensor

so I would suggest you can wait some time

A big thank you for this information

March 20, 2015, there will be a partial eclipse of the sun, I wish I had a camera for that date that covers the full disk of the sun at one time,

do you think that the new camera will be released before March 20, 2015 ?

it would be nice if this new model also have a distance of 12.5mm sensor, hoping that its price is competitive genre (less than 400 € or 500$ !)

she will also have a built-ST4 port ?

which sensor will be used to this new camera ?

If you need a very big sensors, like 1" diagonal then there is CMV4000 in some cameras, but at a price of around 1400-1600 EUR. 1/1.8" e2v Sapphire CMOS sensors are much cheaper (but also smaller), around 400 EUR or less.

I want to continue with monochrome cameras, because more sensitive...
