Re: January Astrophotography Contest

Hi Mike, Sorry for the delay in replying as I have been out of town for a couple of days. Sorry again for my ignorance but with respect to your question do you mean “ is Eta Carina visible to the naked eye?” If so, then in theory, yes. The apparent magnitude of Eta Carina is 1.0 and the naked-eye li...

Re: December Astrophotography Contest

Thanks, Rick,

But we need some more images submitted. I hate having the only image for the month.

Sorry to hear about your equipment problems. I hope you get it sorted soon.

Hi Mike, I live in the north of New Zealand and yes, I have been lucky with the weather recently. Not so in the south where they have been getting lots of rain. Ruined the cherry crop, apparently. But I also get my share of bad weather at times. The indigenous name for New Zealand is “Aotearoa” whic...

Re: October Astrophotography Contest

Anybody know what’s happening to the Monthly Imaging Contest? There has been no comment about Octobers winner and no November contest. Is this the end of the competition?

Re: September Astrophotography Contest

Good idea. How do we do that between two different hemispheres?

Could we extend the voting time and hope some more people will vote. Just an idea.

​Great image Rick. And an interesting nebula. No good for me though as it doesn’t even rise above the horizon where I live. What pallet did you use for processing?

Re: September Astrophotography Contest

Hi Sean,

Thanks for the comments - it is much appreciated. But not such a "short period of time". I started astrophotography with a second-hand Vixen mount about seven years ago and have built up to my current equipment.

Re: September Astrophotography Contest

Hi Rick, Thanks for the kind remarks. Processing these images has been a very long learning curve for me, and I’m still learning. I use PixInsight for image processing. I think it is an awesome piece of software but, as I said, I found it a big learning curve. The stats are as follows: 32 * 480 sec ...
