whats your technique for imaging Venus

[seeker372011 (Narayan)]

Every time I turn my scope (a newt) on to Venus and try to get an image I get massive diffraction spikes...how do you experts avoid this?

Turn the exposure or frame rate down

I've never had problems with spikes on Venus, with my newt. Because it's so bright, I usually use 1/33 or 1/50s exposure, with zero gain if possible.

even at 1/33 I got spikes, however I kept gain at about 20 %..maybe that's the problem
thanks for the tip

Imaging well before sunset against a bright sky also helps (I am assuming you are doing this) and using a filter even if it's a light blue W82A can help reduce glare a little.

Have not had this problem on my reflector but have done my Venus imaging recently at 1/200 sec, 10fps and 15% gain.
