Dear Customers and Friends of AP,



To all interested in seeing the 10" Mak and a few CCD images taken with this

instrument, please visit the AP website (www.astro-physics.com/). Go

to the Products section, click on 10" F14.6 Maksutov-Cassegrain, scroll to

the bottom of the page and you will see new thumbnails of the scope in

various positions, and links to CCD images that I have taken over the past

months. There is also a direct link in the "What's new" section.



Please excuse the images if you've seen better. I am not a really hot-shot

imager, but learning fast. The deep sky images were taken on the 1200 mount

without any guiding, since I have a cheapie CCD camera, not one of the

hotshot self guiding SBig jobbies with an Adaptive Optics gizmo. Maybe

someday Marj will let me splurge on one.



I have to apologize to the many people who have waited so long for this scope

to go into production. Just about everything that could go wrong, did. When

we received the first few prototype optics from Ukraine, they showed great

promise (although they were not fully corrected to the level I needed). I was

assured that all the subsequent production optics would be much smoother and

better corrected since the technicians were perfecting the techniques for

making them. Unfortunately, essentially the entire first production run of 25

optic sets had serious flaws, and could not be used without major rework. I

put all other projects aside for the entire summer and fall of this year, and

concentrated on repolishing and refiguring every optical surface from

scratch. The result is that every optic that will be shipped more than meets

our stated wavefront accuracy, and will perform with the highest resolution

and contrast that this type of instrument can deliver.



We have shipped several scopes, and I will assemble and ship the remaining

ones when I get back from Maui at the end of this month. For those who are on

this production list, I am awaiting the return of the remaining optics from

our coating subcontractor. He has been unusually slow in getting these

surfaces coated, but considering the worth of the optics, I told him to take

his time, do it right, I am in no great hurry for a rush job. So, please be

patient, everyone should have their scopes well before Christmas.



Meanwhile, Haleakela, here I come. We'll be staying at a B&B at 3000 ft

elev\ation with some of the blackest skies anywhere. I'm taking my 92mm EDL

with a Televue Upswing mount. We're also going to try some observing from the

top at 10, 000 ft.



Sincerely

Roland Christen

Roland,



Have fun in Maui. You should contact Jay Renolds Freeman and read his

observing reports from his trip. They are very entertaining and packed with

information on doing astronomy on Mauna Kea.



Clear skies to you,

Jeff "Number 988 in line for the Makg>" G

Thanks Roland! Have a great trip.



Clear skies,

Well, I have seen a few better: Hubble, Keck I, Wynn, and from Galileo space

craft... but that's about it.



Have fun in Hawaii.

Thank you Roland,



Pretty amazing images for a non hot-shot imager. I wonder, will these

scopes enter into regular production?

Hi folks,



I will be uploading some new images taken the last few days with the 10" Mak.

The first one can be found in the Photos section in the M33 folder in the

apug. This image is of the small H2 region in one of the spiral arms of M33.

Mark, Trent and myself are also working on a collaborative effort on another

deep sky project. We are combining images using the 10" F14.6 Mak-Cass, 9"

F4.3 Fastmax and the 7" F7 EDF refractor. I hope we can come up with a decent

result. Stay tuned.



Will probably also add these to the AP web site Gallery as time permits.



Roland Christen

Roland,

Is there a way to post a link to these?

I'm not on the apug, but I'm on your mak/cas list..
