Hey all,
I had another first tonight I dragged my gear down to have a go at Venus while I still can and it was also the first time seeing it with a telescope.

Anyway I grabbed a short avi. and have done a quick stack, it was un-barlowed and not a huge stack but it's so bright I don't know what is optimal. Still I'm happy with it.

I can't work out how to sharpen correctly though, maybe not so much of an issue with Venus but I have seen what good sharpening can do to my Mars from the other day and I'm getting frustrated that I can't duplicate it and I feel once I get that under control all my planetary images will come together.

Try not to be discouraged, from what I understand (which admittedly isn't a lot) Venus is pretty damn hard to image. You don't see much visually either. I think this is due to it being covered in highly reflective clouds and having an extremely dense atmosphere.

Your Mars stuff looked great, so keep up the good work.

Thanks for the comment and encouragement. :)

I would like to get more of Venus though but I might have to wait until next time around, I definitely want to use my x2 and x3 on it and give the scope proper time to cool down.

Hi Jarrod, I think you will get improved results if you can take a longer stack (try to end up with around 2500 stacked frames) and can get sharper focus and less saturation. I often shoot well before sunset. Consider setting up in the shade of a building. This will give you time to get a reasonable capture.

If the seeing won't let you focus, well you are doomed and had better just try again another time!

If you can get a good focus, make sure you are not saturating. And when you stack, normalize the result to about 65%. That leaves you headroom to sharpen up, which will give you a really nice sharp limb.

Good luck!

Hi Ivan, Thanks for the tips.
If things go well this week I will have another go at it and like you said with a much longer avi, this one stacked about 800 or so frames. It was more of of poachers capture and sharpcap crashed on me so I had to use wxastro which I'm not very familiar with. But if I take the time to set up in advance at least I'll be prepared a bit better.

I'll have a go at trying to normalize the result too as that's something I haven't done either.

Thanks again.
Jarrod.
