A fine old pair...

I've been wanting to get these two together since I acquired the Vixen. Skies looked like they might be clear for a while early on, and so it turned out.

Didn't get much observing done, but I did manage to align the two scopes successfully using the adjustment plate. It's a little fiddly especially in full darkness, but very solid once clamped down.

Anyway, these two old birds give a wonderful combination of widefield with the Genesis and high powers with the Vixen. With the 24mm Pan in the Genesis I was getting the whole of Orion's belt in the field of view, then up close on the trap with the Vixen, lovely stuff.

I've finally got the AZ100 working with my Nexus II now, so won't need the DSC when I acquire my AZ100 proper which will save a little cash. The DSC is very nice actually because it does give the option of phone free observing if you want it.

Good to see another Genesis still working hard................

 

Thanks Ken. This one is a cracker I must say, best of the three I've owned and performs well at high powers, as well as the expected widefield views.

No, the Vixen is 1986 vintage, 34 years old but still in excellent condition. They are not made any more, not sure when they stopped.

The Genesis is similar vintage, made somewhere around 1988 to 1993 and still in excellent condition. If cared for well these scopes perform beautifully for years.

They are very different in that the Vixen is an f8.8 fluorite doublet with excellent colour correction and perfect for planetary, lunar and doubles. The Genesis is an f5 Petzval design with a short focal length and a flat field of view so is ideal for very wide fields of view up to 5 degrees with the right eyepiece. Colour correction at higher powers on bright objects is nowhere near as good as the Vixen but at low power that doesn't matter. It is still pretty sharp and will split close doubles well. Both scopes are in excellent collimation with very good star tests, particularly the Vixen though.

Some info on both of them here for background reading.

Stu, you need to fit the Genesis with a 2" diagonal and a Nagler 31mm - gives you a proper 4.81° True Field of view!

Here's mine - 1991 vintage :)

It does have a 2" Everbrite in it Nicos! I have recently sold my ES 30mm but do need to replace it with a 31mm Nagler when I can afford it, performs better at f5 than the ES I think.

EDIT Might try the Feathertouch dual speed too, that would be a nice upgrade!

You can always email TV and give them the serial number - they'll tell you production year.

1986!.. Wow how time fly's. Very nice though Stu. I'll assume a real keeper for sure!.. would be hard to replace I really miss my Vixen SP 102M. Stunner of an achro.

Enjoy.. Rob

Yep, indeed it does Rob. Oldest scope I've had I think, not sure when my Zeiss Telementor was made, I have a Telementor II currently.

Aim is to hang on to the Genesis, FC100 and Vixen FL102S long term as I just really enjoy the different and complementary characteristics of all three.

Had another play with these two tonight, actually did some decent observing with them. I left the Panoptic in the Genesis, and then used either the Leica or Nagler zooms in the Vixen. Was great having the field of view for the likes of M45 and 44, then some power for smaller OCs. I also worked through a list of coloured doubles on Skysafari, the Vixen doing a fine job on the tight ones, whilst the wider ones looked better at lower power in the Genesis.

Quick snap of M45 for the record.
