Reprocessed Trifid

[traveller]

I had another go at reprocessing M20 I captured last weekend.
15x60 sec at 800, then 15x60 sec at 1600 topped off with 5x60 sec at 3200.
Equal darks.
Full spectrum modded Canon 1100D with UHC filter and UV/IR clip in filter.
ED80 with guiding on EQ6.
Somehow the stars still look bloated.
Happy with the results overall, esp given the full glare of the moon.
Comments welcome.

Given the equipment used and interference from moonlight I reckon it looks about right. Stars look okay to me. A linear stretch can make the brightest bloat. I do it anyway and if they look too fat run a median or minimum filter over them later on.

You do need much more total time though, especially with a UHC filter.

Thanks Kevin,
Yes, 35 mins is not much. Currently working on M8 (more red :P) aiming to collect as much as I can before the moon ruins it.

Hi Bo this one isn't as badly affected by the light pollution, so I assume the filter is what helped you there. Like Kevin has mentioned UHC filters cut down the light substantially, so longer subs or longer total time is required. I guess it would be a bit of a balancing act to get enough time for adequate signal without reinstating the light pollution you are trying to quell. Nice job, keep them coming.
