Pegasus Smart Eye for EAA

Hi everyone,
I have been practicing EAA before it was called EAA.
I remember taking apart the old stand alone web cameras and gluing the plastic film canisters to them as nose pieces.
For several years I have been operating under the ZWO environment for both EAA and AP 
I have recently received the Pegasus Smart Eye and of course along with a week of clouds.
I will be using this exclusively for EAA on my various telescopes and posting the results eventually.
I will be using mine with Askar V refractor using both the 80mm and 60mm objectives.
I will also be using it on my ES AR152 refractor.
I have two different sky conditions to use in Bortle 8 (in town home) and Bortle 2 (country home).

Has anyone else on Astrobin received a Smart Eye?
I have searched and found no results as of today.
I would like to see and share our experiences and especially what gear is used.

Please share your setup and your experience with the Smart Eye and what you think of it for the future of EAA.
These are indeed exciting times for astronomy.

I finally got my Smart Eye unit out under the stars for the first time last night.  There are a few issues which are likely due to it being a very new, version 1.0 device.  Nothing major, and I expect those to be smoothed out quickly with firmware updates (there was one update already pending when I checked today).  The biggest issue I had was that some objects, seemingly those with high dynamic range, did not show faint detail in the stacked color image out of the device.  I did a quick stack in SIRIL for some of those and there is faint detail, so this is just a display/stretching issue which I presume can be ironed out and it might even be user error on my part.  The system did produce some pretty nice images out of the box with no processing by me:



M51



M20



M22



I'm genuinely excited to do more with this.  It's my first foray in to EAA and it will be great for outreach and a fun alternative to eyepiece observing for some fainter targets.

The SmartEye offers only one control for stretching: the knob adjusts the gamma.  Did you try that? 

For tweaking other parameters (e.g. black point), maybe Pegasus could make those available through the web interface.  The device seems to do a pretty good job of automatically setting the black point, though.

Dedicated AP software like Siril will always do better than EAA software with the same data.

I did play with the gamma control a bit, but I should have done more.  I was hesitant to touch the device during exposures since conditions were good.  I was hoping that the system would write out the stacked FITS files to the SD card along with the individual FITS frames, but it only writes out the stacked PNGs.

My other wish list feature for this would be some sort of focusing aid.  Watching the star size visually on the screen only goes so far.  The seeing was great that night and I feel like I could have gotten more resolution out of the images.  SIRIL suggested that the FWHM was somewhere around ~4-5pixels (~2.5-3 arcsec), but my visual views of Saturn at the end of the session when it was only ~30 degrees up were excellent, so I think the seeing was much better than that.

I think that this new eyepiece technology will revolutionize astronomy outreach with the public. The best thing about outreach is letting people look through your telescope to get a personal connection to the universe. I plan to get one of these gizmos as soon as it comes out of its  teething problems. Just like software, I do not go for Version 10, I let other folks do the beta testing.

I have had mine out several times and it has performed flawlessly.

I am so pleased with it that I intend to use it as my primary observing method.

It does well on an Alt-Az mount as it has excellent algorithms to stack and counter rotation.

I have done EAA and AP for several years but this makes things so much simpler.

I'm following this with interest, and waiting for a better v2 (whether from Pegasus - hopefully - or someone else).  My hope is that someone will come out with an uncooled version w a modern glow-free sensor (like a 585) and with <90 degrees ocular FOV so less/no coma.  That should be lighter, cheaper, less power hungry and better EP experience.

The IMX533 is glow-free and is much better suited for this application than the IMX585.  The square 3008x3008 IMX533 array is a far better match for the 2560x2560 OLED display than the 3840x2160 array in the IMX585, which would waste more pixels with its non-square shape and would also have a smaller field of view.

The SmartEye has a CPU, which is probably a bigger power draw than the cooled sensor, and the CPU may need cooling anyway.  

I’d agree that a smaller AFOV, say 70 degrees, would work well.

hi, how’s your smarteye doing? mine just came in today but sadly it’s stuck on a red light so i have to send it back 😅

John59 avatar

So far mine has been operating without any issues. Firmware update without any issues.

I am very pleased with it. I know there have been failures for one reason or another.

I hope you get one that works well as you will be very pleased with the results.

I’m considering to buy this SmartEye Pegasus eyepice: should be quite helpful when observing from urban sky.

One question for those luky owners that are already using it: what’ s the difference between what I see in photos and video reviews (eg Smartphone camera observing from the OLED screen in the ocular), and what REAL EYE can see on the OLED screen?

I’ve read that - while cameras actually improve the image with more colors and details - human eye directly observing at the OLED screen can see much more detail, but mostly in grey tonality, with some limited color accents…

Is it true?
Is “color vision” more a marketing hype?

Hi Roberto,

That is a great question and I hope this helps.

It sounds like the "mostly grey" comment you read or heard about might be based on a misunderstanding of how the SmartEye works compared to a traditional glass eyepiece.

Here is the breakdown of what you can expect:

1. It Is Not Optical—It’s a Screen
It is important to remember the SmartEye isn’t a traditional eyepiece where you look through glass at the sky; you are looking at a high-resolution Sony OLED screen inside the casing. The device is effectively a dedicated astronomy camera with a built-in monitor.

2. The "Grey" is Only Temporary
The reports of a "greyish smudge" refer only to the Live View when you first point the telescope.

  • Initial View: Just like a regular telescope, the image starts faint and mostly grey because the sensor hasn't gathered enough light yet.

  • Stacked View: Once the "Live Stacking" feature engages (usually after a few seconds), the computer builds the image. Users and myself can confirm that vibrant colors and details appear on the OLED screen within minutes—views that are impossible to see with the naked eye.

3. Is "Color Vision" Hype?
No. Because the device uses a color CMOS sensor (IMX533), it collects color data that the human retina cannot process in the dark. The OLED screen then displays this fully. In fact, to me and many others the view through the eyepiece is actually "brighter and more vivid" than the same image viewed on a tablet or phone, thanks to the immersive nature of the OLED micro-display.

4. Real-World Trade-offs
While the color is real, the "lucky owner" experience does have some differences from a smartphone photo:

  • Dynamic Range: Bright stars can sometimes look like "blobs" rather than sharp pinpricks because the screen can't match the dynamic range of the human eye.

  • Pixelation: If you have very sharp vision, you might notice the pixels on the screen, though the 2560x2560 resolution high enough to ignore them.

Summary: The claim that the eye sees "mostly grey" on the OLED screen is false for the final image. You will see full color once the stacking kicks in. The device is designed specifically to bridge the gap between the grey fuzzies of visual astronomy and the rich color of astrophotography.

Hope this helps with your decision!

Clear skies,

Johnny

Thank you for spending your time to help me!

This is exactly what I needed to clarify.
