Attaching QHY268C to Stowaway

Jeffc
 

I'm considering pulling the trigger on a QHY268C, but I'd like to know how I would attach it to the AP92 Stowaway.

First off... is the QHY268C (weighing about 2.2 lbs) too heavy for the Stowaway?

Anyone here using a QHY268C with the Stowaway? Or even with 2.7" AP threads?
I'm also trying to figure out what my options are for mounting a IR filter somewhere in the optical path.

I see from   
     https://astro-physics.info/tech_support/accessories/photo_acc/ff-tcc-imaging-train.pdf
that the AP92 Flattner and TC (item CC in the diagram) appear to have male threads on the "camera side".

I.e. Focuser -> Doveloc -> FF/TC (male) -> (female) Camera Adapter -> Camera

AP offers a Canon and Nikon adapter for the FF and the TC, which "thread onto" the FF or TC.
(These are shown as item DD in the diagram above.)

However, what if I don't want to use a Canon or Nikon camera?

In this case, I'd like to use the M54 interface.

Is there an adapter to go from the FF / TC male threads to another standard like M54?
Or a way to go from the FF / TC male threads to the AP 2.7" Female so the regular AP "CCD adapters" can be used?  
(This would also allow the use of regular 2.7" thread  spacers.)

Additionally, there is a need with the QHY268C to add an IR filter in front of the sensor...

Could the filter be added to the OTA/focuser side of the FF / TC ?  
(I suspect not.)

It seems the filter will need to go into the "adapter" for the camera.
So it would be ideal if the "adapter" allowed for 2" filter threads "inside" the adapter.   
(Fwiw, I thought the ADA27-54 had internal 2" threads, but it is not indicated on the website.  I'll need to check my cache of adapters.)

Yes , there is always precise parts.   I'm thinking of getting an adapter from PP that goes from the FF/TC threads to "female" AP 2.7" threads, in a shortest possible distance.   Then I can use the 2.7" AP extensions/adapters to mate with the camera.   

I would still need to sort out a solution for the filter; perhaps a drawer.   I don't like drawers tho as I believe there can be flex there.

Thoughts?

thx

That’s downright dramatic, Chris.

The IMX455 on a 530mm focal length scope produces such a massive field of view you can really frame a lot of targets together.  As you know I'm a sucker for dusty targets and when I got a couple of clear nights around the new moon I couldn't resist choosing this really faint region.  I'm super happy with this scope.  Thanks Bill Long for talking me into getting one!

I've got to put some time into processing out the flare around brighter stars, but I am a pretty lazy post processor and it's delicate work.  I'll get around to it in a future revision. 

Imaged over two nights, unguided with a Mach 2. 

C&C Welcome.

This will certainly be a great travel scope! It would be even more like the Traveler if we could still get a version of the 400 to carry it. That would make a wonderful eclipse trip rig.

Riccardi Honders cooling fans

Hello,

I can’t seem to locate the specs for the Riccardi Honders cooling fans. Specifically, what is the power requirement, and what is the connection type? I’m looking to power them via the Pegasus Ultimate which has the 2.1mm DC jack. 

Your help will be appreciated. 

Thanks,
Barry

Thank you for your kind words Ross!

Nice. Was this flattener test at F/7 or F/8? Pixel scale seems to indicate possibly the later?

I introduced a slight green color cast on the last revision.

Thank you Robert and Stuart!

OK-  Fixed the distracting Halo on the three brightest stars.

On thing that is pretty cool is all the little tiny galaxies in there.  It's tough to see unless you are really looking for them. Sort of a Wheres Waldo on a much larger scale.

Nice work Stuart.  Has a nice 3D look to that dust.  Nice separation from the starfield. 

Dark Nebula are the most rewarding targets for me.  Also the most challenging and at times frustrating.  Keep on bagging them!

I never had much interest in dark nebulae till all of a sudden I'm wanting to shoot a bunch of them. More to come soon I hope!

I really like this target.  I wish I had more clear time to image it.  You did a great job on it.

Nice one Stuart.  Barnard 150 was on my list for this year but I never got to it.  I'll have to wait for next year.
