Dark Skies West Sussex
Christopher Davenport replied to sungrazer's topic in Getting Started With Observing
If you want proper dark, head across into the ashdown forest. There are many areas just off a small lane where you can setup right next to your car. -
Totally Bodacious Dude! (M81 in LRGB)
Christopher Davenport replied to PhotoGav's topic in Imaging - Deep Sky
Gav nice image, but your colour is off, you missing wads ofblue. see peters m81. even my dslr rendition has more blue. won't pretend to know how to fix this or why its happened. -
M81 and the IFN in LRGB 28hrs total

Wow, this is fantastic. Something to aspire to. -
Appreciate the sentiment, it was done in jest, to draw attention to the level of effort involved in both pieces. Both are fantastic contributions to amateur astronomy.

DSLR Rosette - Post your pics
Christopher Davenport replied to Christopher Davenport's topic in Imaging - Deep Sky
So this is interesting result emerging here. A modified DSLR colour balance will be heavy in the red spectrum due to all the added HA. Now even though I colour balance in DSS and select modified DSLR, it is still red heavy. I must say I like the Unmodded colour rendition with the white showing up in the center. i.e Graham image. My Image has the white, but it is overwhelmed by the by the HA. I have been playing in PS with my colour balance to see if I can correct it. This is another attempt at processing, my curves may have been abit to aggressive as I have clipped some back ground to kill n -

Don't know how you do it, but you get the most amazing single sub images -

Nice, I like the colour balance on your image ... I think I may need to reprocess mine as I have all red (probably due to the HA mod to the camera.) -
Great work Brent ... some tips to avoid darks. 1.) create an bias master based on ISO and Temp. (changes at 5c) 2.) Take images using dithering (APT has this option, I use it with PHD2) 3.) Set dither on 2 or 3 and then stack on cappa sigma with sigma at 2 or 3. 4.) Get the SW 0.9 comma corrector, it reduces and flattens. Good luck ... My efforts for comparison and colour matching.

Hello All As we approach the end of the winter season, I have only managed to get 3:30 hrs on the Rosette. Now this tardyness has been mostly my fault as much as I wish to blame the weather. I have had the opportunity to image rosetta, but squandered my time on others. (some of which are throwaway really.) I am slowly learning that my best images are the ones I turn into projects over multiple nights. Anyway, here is the beginning of my Rosette project with my ED80 at 210min. Now I want to push this up to 600 if I can, but I am not sure what more it will add and if it is worth it. So if you d
