A few more DSLR images from country NSW.

2. NGC2359 - Thor's Helmet
37 x 4mins ISO400. Captured last night, so the moon was up for most of this run. Not sure on the focus looking at it now (possibly the focus was a bit soft...?) , although it was set at the beginning of the run with Bahtinov Grapper and a robofocus. Anyway i'm not entirely happy with this one yet so any advice would be appreciated

3. M4 - Globular Cluster in Scorpius
29 x 2mins ISO400

Captured with a modded 400D, all processed with Pixinsight. These images were also a trial of ISO400 instead of my usual ISO800. Am certainly seeing more star colour, which is to be expected I guess as at ISO400 you have halved the gain and so doubled the number of photons to saturation, but am still to decide whether it is a good move for the faint stuff from a SNR perspective...? As always critique welcome and encouraged. Its how we learn and improve
Incidentally I also noticed some light dew starting to form on the primary when I checked the rig this morning, so any advice on how to stop that on a VC200L would be appreciated
