Good effort Zuts, lots of detail appearing.

Add some more time (without the Moon).

Have fun!

Hi Paul
Great effort from inner city Glebe , don’t know how you do it , you must be bordering in Bortle 9
I’m out in the suburbs at Bortle 7/8
Did you use Startools for processing ?
I didn’t hear from you after I sent the sample workflow
Well done !!

Hi Peter, Yes I am happy with the detail, not happy with the star colours though. I may try a re-process without stars and add them back later. Need to work out how though.

As far as the moon is concerned, every night in Glebe is like a full moon.

Hi Ryan. It's a Astronomic UHC filter. However It still allows UV/IR. I have just purchased a ZWO dual band and am keen to try that when the weather improves.

Hi Martin. Yes, thanks a lot for that Star Tools tutorial. This was processed with Star Tools. I think I am getting better but am still not happy with the over processed look I am getting. I am also trying Gimp but that tends the other way, and masking is not so easy. Anyway I will keep at it as I purchased Star Tools.

Hopefully the ZWO filter I purchased will improve things, but guiding is still an issue. For this shot the guide scope was pointing just above a street light which washes out the entire guide image, so I couldn't get better than about two on the graph. There was also a lot of jumps to 4 which meant I had to discard about 20 frames as the stars were too eggy. I have uploaded a few photo's so you can see how poor my imaging location is. The first image is just prior to running a PA routine so is pointing directly south, which is where I had to point to take this image. The second is pointing west for a Lagoon shot. This is better as it is pointing away from direct street lights.

Great work..I guess you are limited in exposure time by the parking regulations... I see a two hour limit....you must have set up and polar align down to F1 pit stop efficiency...
In Gimp there is a doge and burn tool that allows selective brightening or darkening which if you are interested in masks is a quick way out for selective brightening and darkening..I have not used it in Gimp only in photo shop but I find it really handy without creating a mask.

More exposures will also do wonders ..in my case I take many hours and these days and throw out so much...but if you use only the best you notice...

Anyways I would be very happy with such a great result ... it is surprising that you did so well given where you were...

That’s a fair effort for a UHC in Bortle 8 sky. Excellent work. Be aware that the dual band filter, as with all narrow band filters even if the are dual band, will require longer sub lengths pound for pound. If you’re having issues with guiding, you may need to spend a bit of time ironing that out to get the best out of it. Look forward to seeing how you go.

I thought that was impressive before I even saw how bright it was where you took it! I think you'll really enjoy the new filter.
