             Just took some pictures of 3.5day waxing moon while it was about 40-45 degrees above the horizon , landscape around petavious and petavious itself. Looking closely at the 320 x240 picture of petavious there is a faint greenish tinge to the brighter edges of features. Reminiscent of my pictures taken through a SW 120ED  a couple of years ago. Pictures are in the 5ash galllery.

                      Regards philip

For whatever it's worth, I can see CA in my SW150ED. It shows up as a very, very faint deep purple blur around extremely bright, bluish or white stars like Vega, Rigel, or Sirius. Really bright white stars tend to look like they're blue because of this (especially Vega).

I don't think it's really a problem though. I don't see any on the moon and planets where it might actually obscure detail (to be fair I haven't looked at Venus yet though).

Hello 5ash,

 

I somehow can't open the pics in your gallery, maybe silly me, ha, ha.

It would be interesting to see the green tinge/fringe,

Hi, if I google lunar pictures taken with a SW150ED , up comes links to my gallery on cloudy nights. When followed there’s my gallery and the pictures are accessible when you press a few buttons? Strange as I’m viewing  independently?

Thanks , I’ve tried to capture this crater using other telescopes of greater aperture. This ones the best, I’m very pleased so far with the performance of this telescope.

Wow! Nice-thanks for sharing 5ash! Just to be sure, these are from your skywatcher 150ed?

All the ones I posted were taken to test out the 150ED. As I said previously there’s a greenish hue on bright features in the petavious picture . You have to magnify it to see it.

Outstanding images -- thanks for sharing!!

 

I haven't seen green in my 2017 APM 152ED, but I have seen a blue halo around some bright stars, that I found to be related to the diagonal and/or eyepiece.  In general, mirror diagonal + simpler eyepieces = better color correction for low to medium powers / deep sky;  Baader 1.25" prism + Orthoscopics / Plossls for high power / planetary.

According to Sky-Watcher's advertisement in the December Sky & Telescope, the Evostar ED refractor line will be on sale for the holiday season.  The 150DX, which has caught my eye, will be $500 off, and I'm sorely tempted.

 

Those who own or have used the 150ED or DX, what do you think about it now?  Is it a keeper?  Sharp and contrasty?  Still sharp at high powers, say above 240x, without image breakdown?  Do you recommend it?  Even on sale, the 150DX will be $2700, so the investment is not insignificant.  My spouse must be persuaded before I can spring for a new scope. 

 

Comments?

 

Best regards,

 

Austin Astronomer

Jump if the price drops for sure. Mine was very good and could do 450x on Jupiter and over 600x on the moon.

I haven't been able to use mine very much as the weather has not cooperated in the least. The two times I've used it has been great. I liked the DX model too, but I was not too sure about which focuser was used. I got the standard model and just recently purchased a moonlite CFL 2.5 focuser. I think you would be pleased with this scope. It is big and heavy so you will need a study mount. I am using the skywatcher EQ6-R pro. I think your spouse would like looking through the scope too. Go for it!
