Re: The Quest and the Solution – New Product Announcement

This is exactly what I’m looking for as I image with the ASI6200MM full frame sensor. My only wish is some built in way to adjust tilt on the scope, either at the lens cell or focuser to allow us to dial out any remaining mechanical tilt in the scope due to tolerance stacking.

Thanks AP team, I hope I win the raffle!

Under "Features" it says that the flattener has not yet been designed. 


Re: 110 scope musings

Personally, I think this is great news.   This is everything I was looking for with the 130GTX and QTCC with my QHY600.  I'm strictly an imager at this point, but I do have plans to try visual with my stowaway and 130GTX. 

But the monster field that this 110 will produce and the resolution with 3.76um pixels will be mind blowing.

OK... gotta take the bait.  Why is a Mak-Newt perfect for visual?  Inquiring minds want to know.  :-)

helloo Astronuts,

 

Well, you have by now seen the 110 product page, and I have a few thoughts I want to pass along.

 

For the past 2 years I have been keenly aware of trends in this hobby, and have been listening to you active users as to what you want in a scope. So I have spent an inordinate amount of time working out the best optical system that would fulfill a lot of the most desirable things that everyone has requested. I'm leaving out Newts because it's not my specialty.

 

You want:

1)  sharp stars with essentially perfect color correction:   Apo Triplet Refractors, Mak-Newts, Mak-Cass

2)  High power visual instrument with highest contrast and Strehl:   Refractors, Mak-Newts, Mak-Cass with very small obstruction

3)  capable of imaging wide fields as well as the above:   Whoops, that leaves only Refractors and Maks with large obstruction

4)  High power high contrast visual + wide field imaging capability.   That leaves only Refractors.

 

I know that lots of people would like to have a high performance visual scope that has refractor-like contrast and a Mak-Newt fills the bill. But there is no way you can also use it for wide field imaging. As soon as you make the secondary size big enough to cover any modern imaging chip, there goes the visual contrast. Only the refractor can fulfill all uses at once. With today's newest glass compounds we can make a fast refractor that performs for just about any purpose, even for high power visual. So that's how I settled on this particular design. It's a Stowaway on Steroids.

 

Rolando

 

P.S. I still love Mak-Newts and I think they are about as perfect an optical system that exists for visual only.*

And a nice size Mak-Cass for imaging only. But ne'er the twin shall meet to produce both results at the same time.

 

*ask me why

I love this announcement.  I've lusted over the Traveler since they were still being offered for sale.  Too bad I was a poor high school student back then.  This time, there is nothing holding me back..

Of course, it is a little redundant with my Stowaway, but I'm sure I'll find a use for both. 


Re: The Quest and the Solution – New Product Announcement

KHursh
 

Oh man. This is hard. It's the same focal length as my Stowaway, but with a much bigger focuser to allow a fully illuminated and corrected image with a reducer. BabyStarFire will be amazing for wide field imaging. With a full frame sensor, it will fit all of the Andromeda galaxy with room. I can't believe how great it looks on the Mach2. There goes the bank account... if I can get lucky again.


Re: Stowaway with large sensor

Yuxuan Wang
 

Yes, the astigmatism may be a result of tilting in the flattener elements. Roland convinced me to let go of that.

That looks pretty good!   A little bit of astigmatism but more prominent in just one corner, so there may be a little tilt in the image train playing a role.  Thats the really critical eye on it.  On balance its a great result for such a huge FOV! 

Thanks for sharing!!!

Jeff,

Very nicely done, thank you. It brought back a lot of memories. We haven't been to TSP in a long time, but went several times in the late 1980s and early to  mid-1990s and we always enjoyed spending time under the stars there and wandering around west Texas. My limited vacation time eventually took us to Winter Star Party, a good escape from our winters, and Astrofest (Illinois) in later years.

Clear skies, Alan

Awesome Jeff.

I really enjoyed your video. Looks like the place have really good dark skies.

Hoping someday I'll be able to attend to one of those star parties.

Thank you Roland.  It was the brightest I have ever seen the Zodiacal light and the most contrast in the Pipe nebula.  Wonderful week under the stars with AP gear!
