Hello i am interested in getting into EAA i’ve seen good things about it and it’s caught my eye. I’ve used my iphone for a whole year capturing dso and i like the progress but it’s time for a upgrade and i’ve come down to the zwo asi 178 or 385 but just can’t choose which one. Any other camera recommendations would be helpful budget of 300. Also my telescope is celestron 127 SLT

I use the IMX385 based sensor, which is Altair GPCAM3 385C USB3. It is a sensitive sensor and can be used for deep sky objects.

 

It also helps to get a focal reducer. A 0.63 and/or 0.5 focal reducer should be helpful.

I have an AP friend with the 385, and I started with the 178mm and mc versions.

For the longer focal lengths of your scope (even with a recommended reducer) the 385 would be a better solution.

 

If you start with a short refractor (I started with the AT72EDii) the 178 is a better (but slow) general purpose camera for EAA.  I now use my 178mc as a planetary camera and intend to use the 178mm as a guide camera.  My small refractor now has a role as a wide angle EAA rig with a camera that has 385 sized pixels - just more of them.

If your budget can stretch a little, the ASI585 would be a good choice.  Now at $359.  Larger sensor, smaller pixels, good sensitivity, more full well depth.

I was going to make the same suggestion. Great price through the end of the year.

You can search the pinned EAA Gallery topic for terms like "385MC" or "ASI385", etc., and you'll find several EAA pictures taken with an IMX385 camera.

I use a 385mc if you wanted to take a look at my gallery. Be aware I'm still quite new at this so the quality of images varies.

For planets, small cameras can be nice because small pixels provide oversampling and small is all you need to frame the object.  But In EAA, bigger format is almost always better.

I'm brand new to EAA.  Trying to look at Mars tonight with my AT80ED and ASI178MC.  All I got on the screen was a bright white spot like a star.  Can someone clue me in to a good starting point for the exposure and gain to use for live stacking in SharpCap if it's even feasible?  Also, should I be using a 2X or higher Barlow on this small target?

 

Thanks!

I have a ASI585MC and it really is an amazing camera for both EAA and planetary. Large sensor for the price, great wide field EAA views and with slightly smaller fov 100fps for planetary. All the images in my gallery taken with one.

I also vote for the 585. The latest generation of sensors are way better than the past ones. No amp glow, lower noise, much greater well depth, fewer hot pixels, faster frame rates.
