Have not posted an image for a good while. This is taken from Sydney bortle 8 skies (Forest Lodge) and a full moon to stress test my new Antlia ALP-T Golden Dual Band filter. I am pretty please with the result, synthetic hubble style shot from my ASI294MC. Had to resize to 50% to hit the size limit.

John,
Great effort
Well done !!
Looks like the filter has performed well under inner city heavy LP
Forest Lodge would be bordering on Bortle 9 ?
I’ve just received my Antlia Golden ( previously been using L Extreme for nearly 2 years under Bortle 7/8 suburbs )
Do your have your capture details, subs , gain , cooling , cal frames and so on …

Oh also IIS will automatically resize your image if it’s not exceeding say 1.1MB

Cheers
Martin

Nice work that filter seems to be very good. Optolong has brought out the 3nm L-ultimate which I have preordered so it will be interesting to compare the results.

That’s a lovely result. Great contrast under very harsh conditions. I’m also very keen to upgrade to one of these new dual band filters so very nice to see some results coming in. Well done!!
