Hi Doug - quite a few comets are green and is to do with the gases in them. These can be ionized cynogen and carbon which can emit green radiation in green wavelength. These gases vaporise as they near the Sun.
I need 6400 ISO eyes !! No wonder the binos can't spot it and we had high haze all night anyway. Seeing is absolute 'manure' at present and not likely to improve from what I've seen on the weather maps. I was up and imaging last night but it was more an exercise in getting the system all functional and testing setups. Pics were complete rubbish, just fuzz balls but got PHD going again no problem even through the haze. Might try going to bed early and waking at 3am or something over the long weekend. (We have Monday off, Auckland Anniversary). See if the skies are any better at stupid o'clock.
Hoping to find tomorrow morning. What time is best for seeing it?
Hi Petr - no more Moon-free mornings for a while and just at the moment any time is good although you like to get it higher in the sky and it is fairly low in the early evening. The comet is circumpolar and visible from southern locations all night. As long as you can see the Southern Cross you'll be able to see the comet. It's moving through Musca at the moment, just to the right of the Southern Cross as you look at it in the evening.
I viewed it last night around midnight with 4.5" f8 reflector & 21mm eyepiece (43x) and it was very easy to see despite the bright moon and poor sky conditions (light cloud & smoke). Also got an image, here: http://i727.photobucket.com/albums/w...n2013textb.jpg
OK, clear skies here at present, where is it ??
I imaged above A Crux last night between HIP 61404 and HIP 60329 where the track sheet says it should have been on 28th but I can't find anything.
Possibly my CLS filter may be hiding it, need it to clear the moon glow in the sky.
