First Light with 3nm Antlia 50mm filters-NGC6888+Soap Bubble

It was great to see all the wonderful NGC6888 images created for the last FLO imaging competition, so I thought I would share my image captured in Wales.

This is my first light image of NGC6888 taken with 3nm Antlia 50mm unmounted Ha,OIII and SII filters.

The following frames were taken over 2 nights, 7/8September using the ROR system:

16x10 min Ha, 13x10min OIII and only 5x10min SII (ran out of clear sky)

While not intentional, I was excited to see the data also captured the Soap Bubble in the lower right corner. The data was processed using Pixinsight.

That’s lovely, good to see. What setup are you using with these? I’ve got the 36mm set I’ve put together with a ASI2600mm & Esprit 80. I’ve only had time & clear sky to shoot some test subs & I still need to tweak spacing & tilt. However I noticed the ones I did around Sadr show a bit of halo with Ha. SII & OIII seem fine, I was if anything expecting OIII to suffer. Just wondering if you’ve done any bright star tests?

I'm pretty happy with both my Ha and Oiii considering how bright Sadr is.

The screenshots are both Ha. At first I did think the Ha had a funny halo but it looks like its Sadr reflecting on gas.

Thanks Simmo and Space_d for your kind words.

The setup was; CFF160+flattener, QHYFW(Antlia 3nm HSO)/OAG (LoadstarX2), QHY600m and Mesu200. I haven't had the opportunity to try the filters on any bright stars yet.

The bottom pic looks like a misalignment of the channels on the other stars, but you say it's just the HA layer?
