Good evening fellow astro friends, 

I recently acquired a touptek 2600mm, toupteks new filter wheel and a set of antlia 4.5 sho filters + their pro lrgb set in 36mm unmounted. 

i have finally got all the adapters and the time to assemble my new setup. esprit 120 --> pegasus falcon rotator, 1.0 flattener, touptek oag, touptek filter wheel, touptek camera and want to start using it as soon as possible.

as I am new to mono imaging I am not very confident that I have assembled the filters and the filter wheel as good as possible. 
would be great if some of you could give me some feedback on the flats I produced. 
the ha filter and oiii seem to have some light leakage but I am unsure if that will be a problem or if it will calibrate out. (I am already using filter masks that came with the filterwheel). I have not yet calibrated the filter positions.
flats with my esprit and my pegasus flat panel never came out to clean so I guess that the rest are ok. 

I used Ninas flat wizard for the flats. 5 flats for each filter and stacked them in app.

cs and thanks
Andi

Looks fine. But the only real way to know is if it calibrates data fine.

You need to calibrate the lights first, see if it works, like Quinn said. 

Also, let me guess, 36mm filters?     Are you using the included filter masks with the Touptek wheel?

I recommend painting your filter masks a light absorbing black.   The stock finish reflects too much light, causing reflection issues with off frame stars.   I just searched vanta black paint.
