Here's my c-14 cooling down for a night of imaging.

I see what looks like a focuser .Is that what I need before I try to use my SLR on my scope?

I had my C8 out Sunday night for some eyepiece time and imaging.

 

 

Did the quake knock the collimation out?

This was a fun little project; an ETX-90 Observer pieced together from pieces and parts. The tripod, mount, telescope, and finder were all bought off of the used market and while the mount was in transit I picked up an Audiostar controller from Highpoint Scientific. The mount and tripod were originally from an ETX-80 Observer and happed to be the same mount and tripod used for the ETX-90 Observer. The new mounting cradle built into the ETX Observer series makes it easy to swap the scopes. The telescope was originally from an ETX-90 PE and (I think that) the colorful tube looks really nice on the Observer mount. The Audiostar is the modern equivalent of the #497 controller with the addition of the audio chip holding the audio descriptions of objects and instructions. The functions include being able to make these audible on-demand or automatically. Most of the audio is the same as used with the Lightswitch and are voiced by Sandy Wood. These sound bites add a bit of fun to hopping around the sky, or you can just leave them off and enjoy your observing music. The 30mm Orion RACI finder makes it easy to switch between using the GoTo or to go off-road star-hopping. Overall, the Observer is a solid upgrade to the original ETX and being able to piece and ETX-90 together from parts was a lot of fun! Now all I need is a bit of clear weather! :)

 

Enjoy!

I did the exact same thing. Someone local was selling the ETX-90 telescope and fork arms and tripod, however, something was rattling inside the base. I de-forked the OTA and opened up the base to find that the RA motor support was cracked and it had separated from the motor mount. So the base was trashed. The tripod had the EQ tilt plate and was in good working order, almost brand new. I checked online and found out that Scopehed had a brand new Observer base without the hand controller. So I bought the newer base and ordered a brand new Audiostar from High Point. On the OTA, it was just a regular colored blue-ish purple metal OTA. So I found online through ScopeHed was an OTA wrap of a Galaxy on one side and nebula on the other. It was meant as a sliding dew shield of sorts, but I customized it to act as a tube wrap and attached it to the OTA, so now it looks like a PE edition of the ETX-90. When the new Observer base arrived, I attached the OTA to it, hooked up the new Audiostar and attached the OTA to the cradle and it looked like a brand new unit! I have yet to take it outside, but when Jupiter and Saturn come around this summer, I may just use it as a small portable planet imaging telescope. I had someone from CN classifieds 3D print a Bahtinov mask for me, a new front cover and a mount for a solar filter for me. I bought the Solar film online from Rainbow Astro and when the film arrived, I cut it into shape, dropped it into the solar filter mount and glued it into place. So for a $499 original telescope, mount and tripod, I re-built it into a $200 re-furbished telescope!

I found an old photo from 1985. That's me on a cloudy day aligning the finder on my first CAT – my 1978 DX-8. These days I'm grayer than the DX-8. I gave that scope to my brother many years ago.

Greetings,

 

my C6 SE asked me to join the party, how can I say no to the 'little scope which could'?

 

Here is the small orange CAT indoor (ready to go outside) and under the sky at dawn, fully dressed for imaging.

 

Thanks for looking,

 

Marco

Is that an ETX-80 attached to your 12"?

Yes, I use it with a quark for h-alpha. I only put it on there for that and remove it when not in use.

My Meade Model 622 6" f/3.6 Comet Tracker (or ComeTracker as I have seen in some photographs). Authoritative information on this telescope is hard to come by, but it seems that this telescope was briefly sold for about a year between 1985 and 1986. It was sold as an OTA only without rings and I don't believe that it was originally equipped with a finder. I was unable to find a set of rings that fit the tube which is a smidge over 7.2" in diameter (my 7.2" rings don't quite fit it). I solved that problem by bolting a Celestron Losmandy rail directly to the tube. I added a Vixen finder mount and an Astro-Tech 60mm guide scope.

The telescope is amazingly compact and built like a tank. This example has superb optics and makes a fine imaging platform.

On the bottom LHS of the post screen you'll see Select Picture - navigate to the one you want, click 'Open', then 'add to post'. I always preview the post before hitting 'post', but if you mess up, you can always go back and edit. smile.gif

When my mom said I should start a family I'm guessing this isn't what she had in mind. I just put the volume of Burnham's Celestial Handbook in for scale. Right to left: Meade 10" LX-90, Orion 7" Mak, Orion 4" Mak.

My recently acquired 2045. A nicely made scope with a bunch of accessories and aluminium case for 100 gbp. I haven't DPAC tested it yet but the moon looked good at x250. The secondary obstruction is 45% which must affect it but I'm impressed.

Against is the finder and the unreliable tripod adjustment. Focusing is on the stiff side but no image shift.

Hi John

 

Can you post an example image taken with the Meade 622.  A friend has one and I have been trying to talk him into selling it to me.
