All,
 
I thought I would share my recent attempt at the Flame Nebula, Horsehead Nebula and NGC 2023. You can see my last try about a year ago here.

Captured over 8 nights, from Oct 31 - Nov 8, with a total exposure of just under 20hrs and a waning full moon in Bortle 9+ white Houston skies.  I'm shooting to the exposure limit of the light pollution here in Houston, using the Optolong L-eNhance filter, which is acting as a narrowband h-alpha filter for the red channel of my unmodified EOS RP camera.

Focal length is 864mm and resolution of 1.37 arc-sec/pixel, with PHD2 guiding error between 0.6 - 1.2 and an average of 0.8 arc-sec error, where everything was run on my telescope mounted RPI4 connected to the PMC-Eight via WiFi.  Shot at ISO1250 and between 400 to 600 second exposures.

Regards,
Vince

Thanks Ian for your fine image. I will merge this thread with the main astrophotography thread that we use to show what these mounts can do.

Hi all, 
      I think members are encouraged to post images taken with this mount.  Sorry if I am wrong.
This is not great but, taken near the centre of a town so a fair amount of light pollution to contend with and with only 40 minutes exposure, it is perhaps not too bad.  A half size image. Some details below if any are interested.  At least it shows what one might be able to be achieved from a dark sky location and longer exposure. (We are not allowed to travel at the moment.)
Cheers,
Ian

This mount, small refractor and camera make a wonderful, portable, imaging system for medium sized fields.

80 mm semi-apo refractor with Teleskop Service (German) 2 inch field flattener.

Sony A7S, 12 megapixel camera at ISO 2000,  15 second exposures to ensure the centre of the galaxy was not over exposed.  Long exposure noise reduction was not used.

Mount aligned with a laser pointer through the sighting tube but I was not wanting to be too precise so that the image would move slowly across the sensor during the total exposure time.  In fact 1.3 pixels movement in each exposure so there was no star trailing and a total of 104 pixels during the imaging period.  This should  remove what Tony Hallas calls 'Color Mottling' and the effects of any hot pixels - in fact none could be seen in the captured image..

Galaxies (M110, M32 as well as M31) and stars separated and processed individually and then recombined to give the final image.

Thanks a lot Wes. It's great to know ES has trust in its customers to assist them to correct known issues. For me, that is a first for mount vendors.

Kudos to ES and much appreciated 

Off to the garage to work on the mount and finish the setup.  I am sure I will have other questions 

Best
Don

Paul, As I mentioned, my Orion .8x FR looks identical to your FF. On my Nikon, I use 2 different T adapters, see attached pics. Both are just attachment adapters. No additional spacing.

With the wide one I also need one 2 inch extension tube. The 42mm is used with no FR.

Since your T2 adapter has some extension  built in, perhaps a smaller additional extension is required, or a T ring (probably like my wide), with no extension, plus one 2 inch extension. Extension tube kits are available with multiple lengths,  The pic with the camera shows my setup. I would just screw the ext tube on to the telescope.

Hope this helps.  Harry

just to be sure, it is the larger ribbed knob that unscrews ? (before I apply too much force on something unmovable)

EDIT: found them.. two LR41 cells in series.

Managed to it by unscrewing one screw with the small allan (hex) key. Fitted one 2" extender, and am able to focus now :)

The houses opposite my house, distance approximately 100 meters according to Google Maps, are in focus


locked Re: No stars on DLSR #Off-Topic

 

I had to get a different camera as my Canon M50 was impossible to get focus with the flattener. I bought a second hand Canon 650d and had no problem.

Be careful as I have thought it had been switched off when it hasn’t, keeps me supplying more batteries.

If those extension tubes came with the telescope (they appear to be ES extension tubes), then they fit on your scope.  You need to unscrew the collar from the back end of the focuser tube and then screw on one or two of these extensions.  Then screw that collar back onto the end of the extension tube.  Those are probably focuser extension tubes specifically for your focuser.

I should also add that with your type of T2 adapter, you should be at 55mm now.  It appears as though your T2 adapter already has the correct length of backfocus length to go with your camera's lens flange distance.  These types of T2 adapters put you at 55mm, usually.
