Nice report Kohn. You certainly covered some ground!!

Paul

Nice write up.

Next time you are in the Beehive area, check out M67 the Golden Eye cluster. 
Paul

Delos all the way..... (not tried the Pentax though). 72° of pint sharp stars.

Paul

I’ve been very impressed with the Baader mk III and MkIV. Had one for white light and one for HA! But, these are the only zooms that I have tried. 

Paul

That is some very faint work! Good spot. Possibly a step too far for my sky/eyes.

The forecast is looking good for tomorrow though....

Paul

NGC2403 now on my observing list!

Thanks

Paul

Sky Safari is probably one of the best. Loads of information and easy to use.

Paul

Those are some properly faint targets!

Won’t stop me trying though.

Thanks for posting.

Paul

I’m regretting selling my Uni 24 now......

Just had a quick look through the bins. A lovely sight to be sure!

Nice and clear here. So should be heading your way Stu.

Paul

10” flex tube Dob for me. I can just about carry it comfortably in one piece and it has plenty of light grasp. Carry, place, observe. Simple.

Sadly it is out of action at the moment so I have to rely on its 16” cousin which is not practical at all! The little 72mm frac gets very little use as everything seems a bit dim after Dob viewing. I used to have an ED120 which was much better.

Paul

Think that you have covered all the angles there!

A very fine setup.

Paul

Thanks Don 

Much appreciated.

Paul

Yes. That is pretty much how it works.

To move the turntable and thus adjust the height you undo a thumb screw and twist the whole top.

For what your doing this is a superb choice. Btw- do you have the PCI or PCII?

Hickson 44 is waiting for you! Its pretty cool actually, love those clusters.

Thank you all for your advice. 

Despite the obvious charms of wider viewing. I’m going to go for a second hand  Delos 14mm and hope to try a ES92° Or APM eyepiece at a star party in the near future. 

Paul

The M86 chain under dark sky has got to be one of the finest sights in the sky. Very jealous. But I enjoyed the writeup. 😁

Thanks for posting

Paul

Wow! That is a really impressive number of galaxies.

Thanks for posting.

Paul

Thanks John

I don’t wear glasses to observe and would struggle to hold a hovering eye position. Whereas I know that I can observe all night comfortably with a Delos.

Paul

ES92°? That is interesting.

What scope do you use it with?

Nice looking collection.

There is a big gap in the case.... what will fill that??

The visibility of coma is apparent field related, i.e. you WILL see significant coma in a 13mm 100°, whereas it will be substantially less in a 72° field eyepiece.

I don't really understand why you don't use the Paracorr for all your eyepieces as it not only eliminates coma but also slightly flattens the field.

The 13 APM has a small amount of induced astigmatism at f/5 which will be worse at f/4.  The Delos will have a far better edge, where star images are concerned.

 

As for not fiddling around with Paracorr settings, perhaps you aren't aware you needn't do that.  The Paracorr will parfocalize all eyepieces, i.e. simply insert eyepiece B after eyepiece A

is properly set in the Paracorr, and focus eyepiece B using the Paracorr's top.  The setting that results in focus is the setting for that eyepiece.  That's no more complicated

than moving the focuser.  Even if you insert a 1.25" adapter, the process is the same.  You may still need to fine focus with the focuser, but a half millimeter of focus travel is about all you'll need.

The 14mm Delos, however, will need the TeleVue In-travel adapter (AIT) to be parfocal with the 8mm Delos when the 8mm Delos is used with the Paracorr adapter.

Thanks Don

So I focus using the Paracorr rather than the focuser? Sorry about the blindingly basic question, but I’ve only ever found the need for one with wide wide angle eyepieces which i’ve only owned at the long end of things.

I’m sure that I’ve got an in travel adapter from when I had a set of Delos back when there were a few more ££ available for Astro gear.

Can you give a specific example of what you want to observe?

I love the galaxy clusters like Stephen’s Quintet or ARP 316 cluster, but want to get the best from single galaxies like M51. Sadly the Docter is a bit exotic for my wallet!
