It finally cleared up for a while. Although the Moon was shining (85%) and the sky was slightly cloudy, but at least I could take the first if without filter 500x15s, gain 60. Processed FIT from the instrument in PixInsight.

 

Conditions were poor, but I'm very happy with the test.

Recieved my D3 a couple weeks ago. Through some pretty average seeing conditions (clouds, full moon, bortle 7-8 location) I have managed to make a handful of initial test captures.
I'm a complete newbie to astrophography so the following might be of interest to those with zero experience and/or located in less than ideal locations. I will post the out of scope images + my very first tentative processing efforts using PI.
(Cuiv's youtube tutorial is a great guide) I think I have probably erred on the "overprocessed" side of things but was keen to see what sticks and gain more experience by just playing around.
All the following images are in Alt/Az mode with 10sec subs. (Unfortunately I cant quite view Polaris from by city balcony)
Other than the PacMan Nebula I havnt cropped the images so I am sure there are artifacts galore for the experienced eyes out there. Also in regards to the PacMan Nebula this was taken after the recent update which added AI noise reduction.

Overall im very happy and enjoying the learning process!!

I found everything intuitive and faster than the Seestar, thanks to the interesting design that allows fast movements across the sky. Then, the subsequent calibration to three stars and pointing at the object is also fast. The field of view is quite large, so in most cases, it is not necessary to do a mosaic like with the Seestar S30 and S50, and therefore, the exposure time works out better.

 

Overall, I was surprised by the image and the relatively few wasted images. I took the M45, 500x15s, gain 60 and noticed that the subject is also better displayed on the tablet screen, and the program works better with curves. Frankly, in those conditions, I was expecting a significantly worse image, i.e. somewhere in a dark sky, it would make a great image. I downloaded the stitched FIT from Dwarf3 to my computer and lightly edited it in PixInsight. Virtually no difference between the output JPEG. My only complaint is that the FIT is already curve-edited and if one wants a really clean unedited FIT, the user has to stack it themselves from the individual FITs.

 

The shoot started at 19:57 and ended at 22:24, for a total of 147 minutes and the image is 125 minutes long. So the difference is only 22 mins, that's very nice.

Dwarf labs has committed to giving us unstretched files… not sure how imminent it will be but they are stating without reservation that we will have that,

D3 moves much more for dither than what one would expect, however pleasantly surprised that they were able to do so well with it since it was a brand new thing for them to implement, it does look like a couple of centimeters of the image needs to be cropped out because of the way they do it but I don’t consider that a biggie

I photographed the IC434 in poor conditions, Bortle 7, in the city with moderate high clouds. It's only 225 times 15s exposure, gain 60. This test clearly shows me that the IMX678 ( IMX676) sensor is not bad at all, only its implementation in the Vespera PRO is bad. Unfortunately it got cloudy and I could not continue the test. I modified the output JPG a bit.

Bortle 7, in the city, 358 x 15s exposure, gain 60. I modified the output JPG with GraXpert and PixInsight.

 

Interestingly, the temperature reached -3°C during the test, even though the temperature inside the device was 14°C. So, neither the optics nor the instrument were affected by frost like everything else around. The shooting started at 21:53 and ended at 0:23, a net time of 2.5 hours, and 480 pictures were taken. In the end, Dwarf composed 358 images, or 74.6%.

The Double Cluster.  My first attempt with my new D3.  My backyard skies create a wicked gradient.  I only changed the black point in Apple photos.  I don’t know how to actually post process, so this is the best I can get from my B8 skies.

Hey, the clusters are quite recognizable. The king of gradient removal is GraXpert.

Bortle 7, in the city, 262 x 15s exposure, gain 60, no filter, temp -3°C. I processed the output FIT with GraXpert and PixInsight.

Excellent ! No eq mode and filters, bortle 7…can yield even better results really !

 

Congrats and keep posting please !
