Re: Dust storm on Mars

Jozef,

Very cool! We tried to see it (the dust storm) on the 17th but got the wrong side of the planet.

He will need a UV IR CUT filter, true?
Does this make a difference for narrow-band solar imaging? I recently got one for color planetary imaging but haven't tried it for Halpha.

Stunning - much better than I've managed with my C11!
Do you find that the UV/IR filter helps a lot?

More Comet NEOWISE

Hopefully everyone is not too sick of seeing NEOWISE pictures yet! These were all taken with a Canon EOS 6D at ISO 1600, and a Zeiss 135 mm lens at f/2. The 1-4 second exposures were on a tripod, the 30 second exposure was tracked. This comet was a much needed treat for covid summer! Thanks for look...

Powering Point Grey Grasshopper

I've seen several posts here (mostly Mark T I think) referencing the use of batteries to power video cameras with lower noise, even with gain turned up. I was wondering what the best way to do that is. I currently have the ac to 12V power supply that Point Grey sells, and could plug that into someth...

Absolutely stunning indeed! I have a C11 but doubt our seeing is ever good enough to do anything like that.

Does anyone have any thoughts on the viability of this scheme for H or Ca? http://w...

Belated Oct 25 H-alpha

Here are two Ha mosaics taken last Sunday with my usual Lunt 100 and Grasshopper 3 (ICX674). All of the individual frames were taken with a 5x PowerMate. These aren't the best but not bad for the conditions - high thin clouds and lots of high-frequency turbulence. Unfortunately this time of year our...

Re: Solar imaging with a 11" EdgeHD

Kevin, You don't need any additional collimation when you install a full size ERF external filter. Just collimate your telescope at night and do not reverse it around declination axis - so, your scope will not loose the night collimation. Then install an external full size ERF, point the scope on th...
