Thanks again. I always use a gain of 101 with the 533MC Pro as it seems to be the optimum gain for this camera.

Wow!! Thank you so much! This is incredible. I shoot with an 80ED-R and all controlled with the ASIAIR Plus. Is there an easy way to measure LP and read noise with this setup? Thanks again.

Hi, I'm imaging with the ZWO 533MC Pro in Bortle 7 skies. I'm guiding and dithering and can get 300s exposures without any issues but would I be better off shooting 180s exposures given the quality of my skies? I seem to recall someone say that 180s exposures in such light-polluted skies are better than 300s exposures. However, during post-processing my images from 300s exposures look ok - just haven't tried 180s exposures yet to see if there is any significant difference. I also shoot with an L-Pro or L-extreme depending on the target. Thanks, Steve

Hi James, Will these macros work with v1.10.6 or do I need v2? Thanks.

Thanks everyone for your advice and comments. I'll look to recalibrate for each session to make sure the guiding is as optimal as possible.

Thanks. I'll run a new calibration next time I'm out and see if that makes a difference.

My EQM-35 is stiff too so I'm hoping the balance is correct. There is also some minor backlash in both RA and DEC so it would probably improve if I could remove that.

Yes, I always run the polar alignment routine before every session, check focus and then start guiding once on target.

Hi all, I'm currently autoguiding with the Plus and noticed last night that my guiding wasn't as good as previous sessions. It could be that my mount needs a bit of TLC as the guiding got worse when I was shooting near the zenith. Once I did the meridian flip it seemed to improve and then I went for another target lower in the sky and the guiding was better. Should I be running the calibration routine before every session or can a single calibration be used for multiple sessions? I usually don't break down my set up after a session as I normally just lift the whole thing in and out of the house whenever I get some clear skies, which isn't often at the moment. Thanks for any advice on running the guiding calibration routine in the ASIAIR app. Steve

That's a great image! I'm still collecting data on M31 in Bortle 7, but with all the clouds we've had recently it's taking a while to get enough data captured.

That's a really good image! It would be good to know how you processed this in Affinity Photo. I've just captured over 6 hours of data but my image doesn't look anywhere near this. Thanks.

I was out last night for the first time with the ASI533MC Pro and captured the Eastern Veil too. I still have some back focus issues to iron out but generally pleased with my first image using this camera. This was 10x 180s exposures and no calibration files.

That's a great image! M31 is one of my favourites and is just starting to come into view from my garden (it's above the trees and houses now!). I've just got the ASI533MC Pro so looking forward to trying this on M31 once the skies clear. Clear skies!

That's exactly what I thought - the advice seems to say to have the filter as close as possible to the sensor.

Hi Michael, I haven't tried it in front of the FR only because I thought any filter should be as close as possible to the sensor. I'll give it a go and see what happens. Thanks.
