Second attempt at Andromida,

[StarRaver]

afternoon all, This is my second attempt at Andromida, I managed to capture this abot 2 weeks ago but have only just had the time to have a play around with it due to work,

This is a 30 minute total exposure comprising of 30 lights at 1250iso, 60sec, 25 darks and bias

processing is all that as had limited time but I thought i would post what i have done so far

Thanks for looking

That looks excellent for 30 minutes. And there is a lot you can do with in post processing still.

Next step would be to grab some flats, it would really help (or so I think, I'm not that experienced yet).

Keep up the good work!

[StarRaver]

Yes I think it's about time to start using flats, the dark corners arn't that pleasing to look at lol.

Lp filter is a must also

That is a lovely image - excellent!

[StarRaver]

Thank you, it's definitely better than my first attempt will try and go for a couple of hours on it new moon ( weather depending )

It certainly is.

good effort Dale if that unguided even better, you just need to hammer another 100 subs to get more SNR (signal to noise raitio) to reduce the noise or turn the ISO to 800, i find if your taking 60 secs subs leave 120 secs between you subs so the sensor cools enough which will also help with the noise. great effort carry on

[StarRaver]

Thank you, yes this is un-guided, your right with needing more subs, but with the weather and work time is a bit tight.

I will try 800iso next time but I will have to increase the exposure time and with no guiding at the moment I thing I will end up with trailing.I will also try leaving enough time between shots aswell as I didn't really with this, it only had 10 second pause between shots

Thanks

with that setup and accurate PA you should manage 2 min, i did when i had my ED80 on the NEQ6, when i had my old HEQ5 pro i had a 200p on it and unguided was doing 90 secs with no trails. another thing is do you know how to calibrate your polar scope?

Dan

[StarRaver]

yes my polar scope is calibrated myself from watching a youtube video, I have been able to pull off 2 min subs.

With this I decided to try a lower exposure time with a higher iso as I did shoot multiple objects on the same night.

[Daniel-K]

well sounds like your well on your way, the hard thing is sticking with one object when you first start you want to image everything in one night look forward to more results

That image is amazing. Can kinda feel myself being dawn to the dark side..
