Let me think about this for a second...Okay, I've thought about it and I believe you're very wrong.
First of all, do you have Dwarf 3 or have you ever used a Dwarf 3? Or are you basing everything you believe to be true on videos from folks that were given Dwarf 3 units for free, with the agreement that they would produce positive press?
I have one, and was not given one of those early publicity/press units. Mine is from the first production shipment that I got because of a very early preorder.
It produces very nice images over very long periods while in EQ mode. Alt-as acquisition is mostly ruined by the huge amount of field rotation that happens because of how long it takes to get good image quality.
I am also thinking of selling it, and yes, I I have preordered an S30.
Okay, you want to know what's wrong with the Dwarf 3 in the real world?
- It is very slow. To get a decent image literally takes hours of exposure. With polar alignment and 45 second subs, I haven't seen anything useful come from it in less than two hours. Top quality images take longer.
- The JPG output from the scope is terrible. Admittedly this is just my opinion, but it's not good enough for anything besides a preview of what's happening.
- To get decent images requires stacking individual subs and processing in external apps. This is likely beyond the scope (see what I did there?) of what most users of a $500 product will be interested in doing.
- And yes, you have to stack the subs. The TIFF that is saved in the scope is already stretched and is only a bad 16-bit version of the bad JPG preview. It is almost completely useless for any kind of processing because it's already stretched and somewhat processed.
- The software is badly designed and very odd to use. DwarfLab did a rewrite earlier this year and evidently redesigned large portions of it, but it is still pretty bad and cumbersome to use. I've been told that you can reframe an image, but I have yet to be successful at it.
- The software is incomplete. They promised mosaic mode, it isn't there. The promised AI trained noise removal and superior JPG quality isn't there. Or if the noise removal is there, it needs a lot more training because it looks worse than competitors.
- There is no attempt to save settings or even retain them as you move through the seemingly endless steps to set up a shot. And if you go back to redo an earlier step, it completely forgets any later settings when you get back to that step. Don't even ask if you can retain settings from session to session.
- If I really wanted to live with polar alignment, I would have spent my money on something much more capable than the Dwarf 3. I'm not going to get into the issues with how they set up polar alignment because that would be whole other post. Suffice it to say that with a specific set of steps that work around their implementation, I can usually get good enough alignment in around ten minutes.
But with lots of time and lots of work, the Dwarf 3 can produce some very nice images.
I'm going with the S30 for a tiny grab and go scope because of what I've already seen over the last year with the S50. Yeah, it's been a year. I was one of the early preorders on it, too. Early adopter seems like the story of my life.
The S50 produces very good output from a consistent and easy to use interface. It's field-of-view was way too limited for a lot of targets, but the recent 2.1.0 release cured that with ZWOs introduction of mosaics. The same statement holds true for support of polar alignment in the Seestar. Yeah, a few folks are doing a hacked together process that doesn't work very well, but with the mosaic capability, it's not needed.
The Seestar mosaic mode (in the app they call it 'Framing') removes most of the advantages of EQ mode. It removes field rotation artifacts, and it removes walking noise. The other thing I've found in using an S50 and Dwarf 3 side-by-side, is that for similar sized targets, their acquisition time is comparable. IOW--the Dwarf 3 with it's nice large sensor, and the S50 at a full 2X magnification take similar pics of a target in roughly equivalent time. But here's the key point. With the S50 I don't have to use that large slow field all the time. I can shrink it down to the size of the target. In the future, I'll probably use a very small mosaic for all captures because of the image quality it produces. the only real polar alignment advantage that the Seestar mosaic mode doesn't overcome is the use of longer subs, but I can live with that.
I expect the S30 to produce similar results in a smaller package. It has a larger FOV with a smaller aperture, but I believe that will be offset (mostly?) by the superior sensor.
Sorry, but in the real world, at least for me, the Dwarf 3 loses, and it isn't even close.
