Hiten, 

Thanks for all work You done for us.

Your pics are pretty awesome,  hope will have same results in the future. 

 

Im still waiting for delivery of my Infinity

Why would you buy a 414 at $1500 when you can buy an infinity for $500 less.  You don't need the cooling with the low noise infinity.  Please explain this.

Cooling starts to become relevant if you are doing exposures longer than 2-3 minutes due to dark current accumulation. If you think your sub exposures will be less than 2 minutes then the Infinity fits the bill otherwise get the 414.

 

Some folks also want to use the camera for astrophotography along with EAA in which case the cooled 414ex makes more sense due to the same reason.

Hilten, I would hope that the exposures would be under 2 minutes for EAA Observing if not then why not just get into CCD imaging :lol: . Honestly waiting beyond 2 minutes to see an object would either put me to sleep or drastically limit the amount of objects that I could view on a single clear night, so it sounds to me like my buddy who does imaging and is lucky to capture a couple of images for the night.

Do anyone tried how Infinity works with binning 2x2? Had to be similar to older cameras with significant shorter exposition.

I think you would give up color in the process of binning pixels.

Shakes head in appreciation.

And with any luck, anticipation.

Also binning on the color sensor will not produce the same sensitivity or resolution as on the mono sensor due to the Bayer matrix.

Should be better if I will trust You :)

Can You say a word about Your reducer setup used for last photos from C8 F4.3 ? Type, distances... I still looking for it, Your stars look pretty good.

In Fire Capture I'm able to view in color 2x binning of ASI224 in the Preview window but images outputted are b&w.

Kuba was talking about the Infinity. When using binning with the 224 I get color but I see little or no increase in sensitivity. I don't think the ASI224 does HW (charge domain) binning but maybe Sam can confirm.

I used a Meade 3.3 focal reducer at f4.3. I think the 825 sensors will produce least aberrations with a focal reducer at f4.5 or slower. To image at faster than f4.5 either you have to accept and live with vignetting and some coma around the edges or get a hyperstar which allows you to image at f2. But at f2 with a C8 your image scale will not permit viewing/imaging of smaller DSOs.

You will see a sensitivity difference with the HW Bin either checked or unchecked, I don't remember which way it should be.

Only if the camera supports HW binning otherwise it is just adding pixels together. I have not experienced any real sensitivity increase with binning on the 224 (edit: based on photometric analysis I did).

Maybe I can catch Meade 3.3 from second hand.
For now: my local shop have Celestron and AlanGee, can borrow AG and try to play with spacers, they also have all extenders from Baader system. Hope can find "sweet spot" for my SCT 9.25 XLT.

Hi all heres a video just on you tube showing the binning being used when moving to target and some nice views with the infinity.

What are the telescope / focal ratio / ... specifications?

I believe they have a C14+Hyperstar

Thanks for posting the video!

 

Which display monitor do you use for your live views in the observatory? Thanks.
