after being out of EAA for the past 3 years I admittedly jumped on a few familiar purchases and a few hype train products.  a c6, avx mount a 224 camera and the night owl.

 

using SharpCap and my prior knowledge I was quickly able to produce satisfying images without issue.  my only issue was the FOV since the size of the sensor was only 6mm.

 

after a few months, I danced between the 183 and 294..the night owl was designed with a 183 sensor size (16mm) in mind but I wanted BIG..BIGGER IS BETTER RIGHT??

 

so I purchased the 294.

 

 

the 294 was even easier to setup since it came with all the exact sized spacers I would need for back focus from the night owl..perfect

 

I started it up full frame..HIGH REZZZ...sharpcap polar align was a breeze with this 23mm chip..it saw like..like..the universe almost !!

 

but it also saw vignette and coma and the occasional sct things like some reflections from the reducers or internals or whatever..idk..

 

I COULD NOT GET A FLAT FIELD..TOO MUCH VIGNETTE TO GET A GOOD FLAT>>BRIGHT CORE OR EDGES frown.gif

 

 

so then I dabbled with the celestron 6.3 reducer and had an amazing 3 nights in a row of EAA..I saw little things and big things..things I've never seen before!!

BUT the edges were even worse but the vignette was managed by a flat.

 

so then I reached out to starizona and they gave me the tested resolution size for the night owl and a 183 and 294 sensor..the size doesn't fit one available in SharpCap so I settled on 

3104X2116..they recommended 2848w by 1952h

 

flats corrected the vignette (1.5s) keeps the core tame so it doesn't blow out during a stretch and the corners are nicely blended.  a few edge areas show some needed help but its just the limit of what I am working with at this point!  the 294 camera is just super amazing and the night owl reducer is proving a great option!  a 224 at $250 is super as well and will service me for planets.

 

ill provide the images here and it should be fairly obvious what is what but feel free to ask any questions!  I was tempted to sell the scope and reducer and try another combo but now this system is proving to work great and the 294 is of course very flexible for any wide field scope that I will be adding in the future.

 

you can also subscribe to my youtube channel below..it mostly has focused on drone and fpv content but will be shifting to astronomy related materials.

That's all very interesting.  I just subscribed to your YouTube channel :)

 

So I assume the Night Owl is not suited for DSLRs  due to the backspace requirement?

thank you..trying to keep it easy and basic to get the most out of eaa and not overcomplicate it.  and thanks for the sub..I promise to deliver.

 

the reason you wouldn't use the night owl for a DSLR is that it was produced for a 16mm sensor size and below and to be an upgrade at a decent price for us sct users who do not want to commit to something like hyper star at 4-5 times the cost. (except for the 6 inch one)  you can reach focus with some kind of rigged up spacing but your useable image circle will be a mess since its bigger then what I was managing to work around.

Did you give Starizona a call?  I ordered the Night Owl and a 294MC at the same time.  While talking to Starizona I mentioned that I had a C6 and they did not recommend this sensor combination, at least not without cropping the image down.  I was ordering the 294 mainly for my WO Star 71 so its not a problem.  The largest they recommend is 16mm.

all the details are in the post. the size they recommended over email and what I had to use.

I'm very interested in this topic, I'm purchasing the 294MC very soon and have been considering either the Starizona 0.4x reducer or Celestron 6.3 reducer, leaning towards the latter right now. Can you elaborate a bit more on the edges and vignetting you saw with the 6.3? I have no first hand experience yet with these kinds of issues that surface in imaging, so I'm trying to gauge if the problems you saw are something I could live with as I get started with EAA or mitigate down the line with flats, etc.

Also, the images you posted seem a bit grainy or low res. Is that a flickr issue?

EDIT: image quality issues appear to have been due to my poor cell service at the time, the pics look great now

the pics are labeled F4 and F7..you would have to choose for yourself if you're willing to deal with it or not.  I think the cropped sensor and starizona reducer perform a lot better then the celestron reducer.  the best option would be to move to a refractor that can handle the full sensor size.  I will add a 70-80mm to my setup and have the best of both worlds.

 

using the celestron reducer at full sensor resolution, you can always use the zoom feature to clean up the large ring on the outside by simply not looking at it.

 

the starizona reducer cannot be used effectively without cropping the sensor in SharpCap because you cannot create a flat that doesn't correct the entire field of view due to the large amount of black around the frame.  so you get either too dark corners or too bright center and that ruins your images as you stretch them.

I have a Celestron Cpc 1100 And this weekend I was going to buy the night-owl and the zwo294 Pro From Starizona . Maybe the zwoasi183 might be a better fit , Have to talk with them at Starizona .

The ASI294 gives you more options.  You can expect to be a bit under-sampled when using it with the C11 but depending on your goals that may be very irrelevant.  You just define a smaller ROI and you won't have excessive vignetting.

 

The very good dynamic range of the ASI294 can make things nicer.

 

But if you want to get every last bit of potential detail out of your system so that you can be zooming/enlarging on your screen?  That's the ASI183.

Anyone tried the asi533mc with the night owl. The sensor size seems like a perfect fit.

I use my 533 with the night owl reducer. The night owl image circle and the 533 sensor are both 16 mm so you will have some vignetting and have to use flats with it. Easy to do and works perfectly.

The Starizona website has pics taken with a C8 and ASI183MC using the Night Owl - (the 183 and 533 are both 1in sensors and have similar overall FOVs, but the 183 is 13.2mm x 8.8mm while the 533 is square - 11.3mm x 11.3mm) . If you zoom in and "pixel peek" the images (e.g. M51), you can get a a good idea of the star shapes that this reducer produces at both the centre and off axis.

I use a C8, Night Owl, AVX, and ZWO 533.

I think the field looks flat, but there is a bit of vignetting if you don’t use flats.

Here’s a single 2 minute frame of Lagoon Nebula without flats or darks from last Saturday night.
Frame is auto stretched from ASIair v.1
but not edited.

Thanks Phil! That's exactly what I wanted to know and see. Great pic. I've been thinking of getting a C8 or C9.25, so I can do some planetary and zoom in on things some more, but wasn't sure if I'd want to go the Hyperstar route (so I could also do wider field stuff). The Night Owl seems like an interesting alternative and would make a Cat very flexible as well.

Night Owl isn’t quite as fast or as wide field as a Hyperstar, but at a fraction of the cost it’s a win in my book. Plus it’s light and super easy to set up or change up equipment.

I’m a big Night Owl fan.
The 533 is an awesome camera and pairing too.
