Hiya guys,

 

I finally got me that 32mm Plossl to use with me Orion 180 Mak.

 

Took a chance on the SkyWatcher product and was pleasantly surprised. Nice multi-coating, rugged housing, and they even put the umlaut on the 'o'. How about that! :lol:

 

Checked it out during a few sucker holes this evening; a nice gain in true field. No ghosting, excellent contrast and aberration free nearly right to the edge.

 

Simple 4-element design. Good tool.

 

Cheers,

 

Neil. ;)

Looking good Neil, I like the simple design of Plössls (had to work a little for that umlaut). That should get you to about 0.6 deg at 80 plus x I believe.

Hi,

 

I just got in from looking at a low, brilliant Moon with my 180 Mak. I was testing my new 32mm Plossl.

 

I can report that the entire Moon could not quite fit into the field of view. But it's darn close!

 

Still, there's plenty to see with half a degree!

 

The image was dazzling to the eye but razor sharp, despite its pitifully low altitude. The great ray craters emanating from Tycho and Copernicus were, quite simply, spellbinding!

 

Contrast is excellent. The crater fields running along the eastern limb are a great joy to behold. No chromatic aberration save the usual (slight) differential atmospheric refraction which comes with the territory at such low altitudes.

 

A most happy camper!

 

Thanks,

 

Neil. ;)
