New Purchaser of the EXOS 2 PMC-Eight

Brad Becker
 

Hi everyone,

Guess I'm looking for a bit of assurance on my purchase of the EXOS 2 PMC-Eight yesterday.  It's being discounted anywhere from $100 - $200 and have a few days cancellation window.

My desire is to start with nothing more than a DSLR and lenses ranging from 20mm - 300mm to reduce ISO and extend exposure for AP but future proofed to eventually slap on a modest scope for visual and AP work as my knowledge grows. 

I've been out the picture for decades and parsing through the discussions the digital world of astrophotography is both stunning and frankly a bit intimidating in the myriad choices, a far cry from the film days when I was gas hypersensitizing Kodak Tech Pan 2415 on a LX5 eyeballing 30 minute exposures with an off axis eyepiece!

I'm looking through the discussions and it's not sinking in yet but hopefully you can jump start me.

Is this mount a good first start for my intentions?

What would be the first accessories to consider hardware/software for a newer user related to making PA easier, improve ongoing guiding accuracy, and image enhancement?

Will the included polar finder scope be sufficient?

I plan to go mobile with the equipment.

Thanks!

Hi Jerry, I believe I have I just successfully loaded the latest firmware onto my iEXOS100. I have tested the mount controls and all worked OK. Is there anyway of actually confirming the latest firmware is now installed please.
Many thanks, Brian

Omar, that's a great shot, would love to have a go at it myself but a little too low for me where I am in the UK
Good work man

Hi Wes,

Thanks! Yes, it's the Eagle Nebula with the pillars in the middle. At some point I would like to get closer with my SCT. And yes, I used the ES 2 inch field flattener. It makes a clear difference.

I used the ZWO 31mm narrowband filters (SHO). They're 7nm wide. Guiding was pretty good for the most part. I did throw out about 20% of the frames.

Bill

You load the configuration manager on your PC.  You need a usb to serial interface cable with FTDI chip.  And you will need the driver for the FTDI usb to serial adapter cable.

This will enable you to use the configuration manager to update the firmware.  The pmc8 can remain in wireless mode during this operation.  No need to change anything in that regard.

Omar, one other thing.  Do you have a field flattner?  There is no visible coma that I can see in my phone at least.  That ES 102 seems to rock!

Nice Omar.   Towers of creation?

What filters you use?  Guiding looks fine, nice stars.

I'm another iPad user, but have a PC I could use to do the firmware update.

What programme do I install to get this "PMC-Eight Configuration Manager Firmware Update tab"?

Hi Jerry,
i was just wondering, on my EXOS 2 PMC-Eight Mount , I have it set to operate on serial port, not wireless.
If I do this update to the mount, will it change it back to wireless ?

thanks,

Hi Jerry,

I seem to recall hearing that in one of the YouTube live vids recently...

Would the motor still run, but just not have enough oomph to turn the larger gears?

If the voltage drops below around 10.5 Vdc then the motors will not provide enough torque to drive the mount and it will start to stall/ratchet.

Hi Koen,

Have you checked to make sure your power source is supplying enough voltage?

I was experimenting with my mount last night and thought it was connected and appeared to be operating correctly (I could see the RA spindle turning) I could not detect any physical movement of the mount.

Fast forward to this morning after recharging my power source (rockpals 330w solar "generator") the mount is operating properly.

Might just be a coincidence, but the state of charge was pretty low last night, around 20% maybe, and I know that the 12v DC output on the rockpals is not regulated so the voltage was probably well below 12v.

Maybe Jerry or Wes can shed some light on this...

Hope ya get it worked out!

Thanks Bill, I've only been at it about a year or so now, still learning all the time.
The PMC8 mount is a recent upgrade, it handles the Newt and all other gear just fine and for the price,  I think its pretty game changing.

I use a ZWO DuoBand  (narrow band ) filter on my 294 colour cam whenever I'm doing nebula shots, it works very well.
I would love to get one of those high-end quad band filters , but cant justify the >£1000 price tag!
Ah well..

Thank for your info Bill, perhaps ill try a moon and sky glow on a galaxy.

Thanks Wes.  I used the shorter exposure due to time on a work night.  My goal was 60 frames at 1600/60s to increase signal but just couldn't hang much past the meridian flip.  I will go a bit longer on the next session when I have the night and following day to myself.  The previous shot you saw was the Sagittarius Star Cloud and the edges were trailing.  The flattener did the trick.  Mount is performing outstanding and trend lines in PHD2 looks like they are riding on a rail.  I do a calibration at the start of each session and consistently average around .5 total error if not less.  The cal also seemed to help guiding performance.  Not up to Dave Cherry's level (yet :-)) but getting better each session.  Processing is killing me but progress is happening.

Gotta say that I love this mount!

I can’t remember what you had prior to the field flatner but man oh man those stars!

Nicr all around. Real wide field.

That triffid has a beautiful blue green lobe if you expose it more to go a bit deeper.  You. Can see it but it is faint.

Really nice image
