Re: Images of the moon taken on August 7 with the C14 (part 1)

 

Yes, Christian, this is absolutely inspiring work.
Thank you for sharing it!

Can't wait to set up a Hyperstar with my new C14 EdgeHD.
Currently using a humble iPhone 6.

Best wishes!

Lee

Dear All,

Please find a first set of images of the moon taken last August, 7 with the Celestron 14, Basler 1920-155 camera, Astrophysics X2 Barlow lens and a red filter.

Let's start with the classics :

Clavius :


Tycho :


Maginus :


Deslandres :


Straight wall :


The nice riles of Flammarion and Oppolzer :


The area around Bode with a lot of cracks and riles :


And the nice Philolaus crater :


More information is given there :


And more to follow ...

Best regards

Christian

Re: focus inside tube

Kerry,?
To clarify.?
? ?The shipping bolts attach to the mirror holder with it all the way to the rear. This causes the the focus to be in the tube when on a sky object. With the locks removed you will able to move the mirror forward by turning the focus nob. This will move the focus back.

Re: focus inside tube

 

This has been my single biggest complaint of Celestron so far; critical
items not appearing in the C14 user manual. The hex shipping screws are at
the top of the list. Without first removing those screws, you can ruin your
primary if you try to wrench the focus knob beyond its resistance. In April
spent at least an hour fretting about it over my new C14 EdgeHD, then
desperately ran to CN for data.

There, 1 or 2 helpful souls on page 3 or 4 of a discussion had answered the
question last year for another member.

Anyway, for your apparent focus issue you should call Celestron Tech
Support.

The focal plane of the scope is too close to the front of the telescope. In fact it is welll inside the telescope.

No it's not an edge, it's a C14A. The two knobs are shipping screws and have to be removed completely. Why Celestron's manual??? doesn't mention this,I can't imagine.

In case the corrector plate needs to come off, guidance is available in the files section of this group in a document by Greg Nowell:

? <> ?

This document includes instructions for removal and reinstallation of the corrector plate. Some details of how the corrector plate is mounted for centering may differ from the document (e.g.. adjustment screws instead of shims).

Thanks, Gary. ?I’ll get in contact with Dean. ?In the mean time, I’ll try what you suggested to temporarily fix it.

There are gaskets/washers between the secondary mirror holder and the corrector lens. Yours are probably old and shrinking up thereby causing them to loose their grip. When your secondary mirtor rotates you loose your collimation.

I believe Dean at Starizona is replacing them with newer ones that have a rubber composition. You might want to check with him.

In the mean time you can remove the secondary mirror and reach in with your fingers to hold the secondary mirror holder and turn the part on the outside of the holder. This is fairly easy to do but you probably need to replace the washers with new softer ones with some grip.

If you have never removed a corrector you should seek guidance on removing, reinstalling, and most importantly realigning the corrector lens. It takes a certain amount of experience to do this by eye in the event you opt to remove and replace the gaskets/washers.

Needless to say you will need to collimate once this is done with the secondary mirror in place then once again with the HyperStar lens.

If you live near Starizona Dean will do this for you.

My C14 is vintage 1999 or so. I’m starting to use it with HyperStar now. One thing I notice is that when I’m messing around removing the secondary mirror and attaching the HyperStar lens, it is pretty easy to rotate the secondary mirror holder relative to the corrector. What mechanism is supposed to keep it from rotating? Will I have to remove the corrector and tighten something up inside?

Re: C14 dust cover ( corrector end not e.p.) replacement.

 

I am using the cover to make an off axis 6 inch solar filter holder for my C14.? I want (and have found and purchased one) the oem product because I do not want to have to worry about fit.?
Re: C14 dust cover ( corrector end not e.p.) replacement.

 

Certainly on first impression the cover is vital and if you lose or somehow damage your OEM cover the first instinct is to replace it. ?My gripe with my OEM cover though is that when I stand the scope on gravel it gets a bit dinged/scratched. ?Yes I could take the trouble to stand it on a blanket or something but when breaking down at night these details slip. ?

There is a cheaper solution, however, which I have used on my Newtonian, and which would work with a C14 as well. ?

Cut a large cardboard circle. ?Then cut a cardboard strip, maybe 2 or 3 inches wide, equal to the circumference of the scope. ?

Now, get yourself some nice duct tape (there are many colors) and bend the long strip into a circle. ?Place it around the perimeter of the cardboard circle and secure it as a circular band. ?Now put tons of duct tape to secure the two pieces together and add some thickness and durability.

It makes a nice cover on my 10" Newt. ?Still using OEM cover on the C14 but now that I know this trick how to cover a telescope objective is not much of an issue. ? GN
