Sharpstar 94 with 0.8 reducer ASI1600mm

Its cropped a little but looking at the stars in the corners I still need to add a bit of spacing.

Thats a lovely example.  Interested to see how you get on with the stars.  Mine had astigmatism that couldnt be resolved

Lol Yes I do suffer from star anxiety with it, I’m hoping it’s the back focus. So far I’m not too happy with the scope. I bought the starsharp dedicated field flattener with a recommendation of  100+mm back focus and at that length I can only focus on objects 20yards away. I reduced the back focus and managed to reach focus but the stars are a bit ovate around the edges. This image, I used the .8 reducer.
 

Unfortunately I purchased the scope Dec/Jan time and didn’t get it out the box for 6 months to test due to the weather, otherwise I would be putting it back in the box and returning it.

Thats a shame, but I dont think the stars at all detract from your image, it's fantastic and eye catching.  I also bought the 94 0.8x FF, and was told the level of astigmatism etc was to be expect with the design of the scope and flattener, and that I will need to use post-processing to correct the star shapes.

Nice pic, looks suitably ethereal!

Thanks Adam, You’re right I can live with it and with a bit of processing it has come out alright. I’ll just add a few more hours of Ha to it.
