Hi, i have a Celestron ExploraScope 70AZ, when i look at the saturn or jupiter (low or high magnification) the picture is clear if the object is at middle of my viewing but blurry and color mismatch if the object is at left side of the viewing.

For a long time I wanted to shoot this frame, probably from the early days of my astrophotography adventure.
Finally after all these years I managed to get a decent result of the 'stuff' between these two beautiful nebulae. Fairly happy with the image but always looking for improvement.
I hope one day to redo this all with a mono camera and filters.
Apart from NGC1499 , M45 and the Baby Eagle Nebula no idea what else is in the picture. If you happen to have an idea feel free to educate me.
Some info on image and capturing:
Widefield Pleiades to California.
Taken over 2 nights with a total of 11hrs 25min integration.
With a stock Nikon d610 and Nikkor 85mm 1.8 objective.
Tracking was done with the Skywatcher Star Adventurer.
Lights and all calibrations frames were stacked in DSS.
Processing was done in Adobe Photoshop CC using Adobe Raw, GradientXterminator plugin, HLVG plugin, Nik software plugins and Photokemi action set.
The weather has been so bad I have had the time to finish a video on using astro filters with the Nikon Z bodies and Nikon camera lenses. There is a manual alternative to the FTZ allowing 1.25 inch filters to be fitted between camera and F-mount lenses, and for some lenses and end of lens solution make sense. FAstroTZ is described here:
Having upgraded from canon 1000D to Nikon D5300 how do users of the 5300 find it for Astro I will be using with APT , and how do you take flats as I can’t use Av mode as there is nothing in tools menu to choose no lens , do you use in manual mode and look at histogram ? .
