Astrophotography done with ESPMC-8 #astrophotography #EXOS2

Chris Welliver <chriswelliver@...>
 

Hello everyone, I’ve been following this group for a while now, trying to learn the ins and outs of astrophotography with my EXOS2 gt Mount. I took this photo last weekend with my William optics Spacecat 51,(after the sky glow and atmosphere cleared up), and I’m pretty happy with it. Hope y’all like it.

Huh...  

That looks pretty similar to the polar finder adapter for the iExos-100.
If ES were to develop a variant of that adapter, that one could attach a guidescope to, that would answer it for the iExos-100 camera folks...

Some are better at it than I am, but I was never able to get side-by-side balanced well enough for me.  I found a longer dove tail with the guide scope mounted under worked really well.  It's a much cheaper config too.  You just need a long bar...long enough to make sure the guide camera doesn'tclip the mount.

Hi Gernot,
Thanks! I'm glad it is useful.

For focusing at long focal lengths, I'm going to say the most important factor by far is the "seeing".
I've tried automated focus routines, like the ones in the SharpCap tools, and I've used my Bahtinov mask as well. They work pretty good, but they work much better when the seeing is good. If the seeing is bad, none of them work for me and you end up fiddling back and forth and get no real improvement.

When I shot the footage of Jupiter the other night, the seeing was very good. I focused without using any tools other than my eyes and electronic focuser buttons. I added a Crayford focuser to my SCT and modified it with an Orion AccuFocus kit (little electric motor that attaches to the shaft on your focuser). However, if the seeing is good, I think you can achieve decent focus with the stock equipment.

Atmospheric is a great tool for predicting what your seeing will be like. It's a weather forecast, so its not 100% accurate, but it seems more accurate than others I've tried.
https://www.astrospheric.com/

Another thing that will affect your seeing is the altitude of your target. The higher the altitude of your target, the better the seeing, because there is less atmosphere to contend with. The other night, Jupiter was less than 40 degrees above the horizon, which is really to low to even be trying in my opinion, but the seeing seemed very stable, so I gave it a shot. Really, I would rather my target be at 50 degrees plus. Mars is a great planetary target this year because it is climbing above 60 degrees. 

Decent focus will be easier to achieve on M57 and M13 for a couple of reasons, I think. One is that they were probably above 50 degrees and two is that you were able to use a shorter focal length (less magnification).

I'm curious what others do for focusing as well, especially at long focal lengths. It is still one of my biggest struggles after many years in this hobby.

Hi Daniel, at present I use just a DSLR but not guiding (yet). You can by a side by side saddle to mount 2 items next to each other, I.e your DSLR and guide scope/camera.

Personal preference mainly.

Kstars interface in Linux may be different than on a Mac, but I find it less intuitive.

The sky image isn’t as representative and the catalogue seems incomplete vs whats included with Stellarium.

I’m not familiar with using the DSS sky surveys.

Bob,

I'm doing a write up but you probably don't want to wait.

This is a quick and dirty version of what I did (and assumes you've installed and added your geo, time, telescope, eyepiece parameters, etc.):

1) Installed Kstars - I don't like this program, but it includes the INDI pmc-8 driver you need for your Mac to talk to Stellarium. I don't recommend installing INDI drivers any other way on the Mac, but you can try if you want to remain frustrated
2) Start up the INDI control panel in Kstars and select your mount (EXOS2-GT), then run a local service on port 7624 (this is automatic after you Run the service)
3) Connect to the pmc-8 wifi
4) Connect the INDI control panel in Kstars to the pmc-8 - you have to set up the connection controls from the Configuration menu first (select Ethernet, TCP - the port that is listed is the default - leave it alone)
5) Start up Stellarium
6) Activate the Telescope Plugin in Stellarium and select the Telescopes tab
7) Configure the Telescope Plugin - select Telescope controlled by - INDI/INDIGO radio button
8) Scroll down to INDI settings - you should see localhost 7624 in the Host settings, click Refresh Devices - you should see "ES EXOS2-GT PMC-8" appear in the devices window
9) Click OK and go back to the main Telescope Control window
10) Click Connect - you should now see "Connected" status under "Telescopes Controlled" window for your scope

You're now connected to the PMC-8 with Stellarium on your Mac.

One disclaimer - Stellarium won't solve your alignment issues, but it does help me find things in the sky. Stellarium has a virtual hand controller that you can use to slew your scope to look for things you want to see until you get polar alignment issues sorted. It also has the usual goto features.

Hope this helps.

Hi Bill & all,

Thanks for sharing Bill. Your writeup is very helpful information for a newbie and it is useful for me to see how you are proceeding.

I tried last night to get some pictures of Jupiter and Saturn but I was struggling mainly with focusing, I guess.
I also saw that Jupiter is quite bright compared to the moons, so I could not find a good exposure to get both well covered.
So my learning from this is if you want a good picture of Jupiter and the moons you need to combine two pictures.
If there are experts out there who know how to do it differently, please speak up.

My main issue however was with focusing. 
I have reduced the exposure to be able to better judge on the sharpness of but since I have no focuser it was very much fiddling and no good result.
As a side note I had less issues with M57 or M13; less not meaning no issues...

How do you focus -especially planets?
I would appreciate to get some hints as I am new to astrophotography.
Comments from anyone very much welcome !


Greetings
Gernot

Dave,

Do you mind sharing your current PHD settings (assuming you are using PHD).  I tried my 8" SCT about a month ago and had horrible star trails.  I wanna try again but would like a baseline to start with.  Sounds like you have one.

Thanks,  well I tend to find lower hysteresis values help with 1.5 seconds exposure, with the 200pds tube on the mount the PMC loves to be nudged more frequently than with a small refractor 😊

definitely use a dark frame on your guide camera and get stars as small as poss on there as well.   Yes  I Am guiding both Ra and Dec, total error 90% of the time below 0.5 unless the wind blows my tube!

 

I’m with you, I like diffraction spikes,  good enough for Hubble, good enough for me 😊

Sorry Dave. I was so overcome with the image I lost ability to type.  Really nice.  Sharp focus to, what with the spider flare and all.  I love to see those things on the bright stars in a nebula picture.  Some see them as an issue, but not me.

 

You do anything special to get .5” guiding?  You guiding ra and dec?

Just an update Jerry, so It seems that this issue is not something that I have happen when I'm connected. It only occurs on the app when not connected to the PMC8 system. I used the Fire HD 10 tablet all night Friday, and was able to get 1min exposures unguided. 

Thank you and Dan both for addressing this.

Edwin,

I am using APT’s plate solving, and GoTo++ to center. For the focal length it has been auto-detecting for me, I haven’t changed any of those settings.


I also use Backyard EOS, as they’re focus/framing has been working very well for me!
