Hopefully you saved your .ser file made by mistake.  I made exactly the same mistake with SharpCap, and was horrified to think my data was gone.  Fortunately there is a very nice program called SER Player that can not only play .ser files, but also extract each frame to the file type of your choice – including .tiff.

This is my solution, no 3D printing required.

It's a Jubilee clip and it works really well.

Notice it is a genuine Jubilee Clip not a cheap copy so probably costs a bit more.



It would be nice if ES included one of these in the box with the unit.

Thanks Jerry!
That explains it; it is an artifact... Live and learn. So nobody else go hunting for it; it only exists in my image train :)

This was my solution to this same issue. I found that this Nikon 90° viewfinder for a SLR camera works very well. I simply attached a half of a .965 bolt case over the threads from the viewfinder, then just slide it over my polar scope eyepiece. Definitely a improvement over kneeling on the ground.

Yes, it is called the "Reflection Nebula"..... It is an artifact in your image caused by the bright star Vega reflecting either off the clear camera chip cover or another optic you may have in the image train. I have seen this much more pronounced when filters are in the image train. This reflection occurs typically when the bright light from the star is reflected off the chip surface back up to the protective glass over the chip, and then back to the chip again. 

Rest assured, it is not a real nebula.

Hi All, so it's been cloudy here for months, it seems. Finally gave up on completely clear skies because I wanted to get out and test out a few things. Vega was just about the only thing not covered by clouds, so I was doing some test shots and noticed a small green oval nebula. At first I thought, is the ring nebula that close to Vega; nope and this thing is much smaller. Maybe it is just an artifact of some sort, but it does not look like an artifact to me. The only thing is that I can't seem to find any information on this object. I don't think I've photographed Vega before, or at least not in many years.

Anyway, I was wondering if anyone knows what this nebula is... does it have a name or number? Also curious if anyone else has photographed this thing. I'm not sure how easy it is to see in the attached photo, but it is just off Vega in the center toward the upper right... tiny green oval.

This is 10 60s subs using the ASI294MCPro, AT80 APO, 0.8 reducer, and, of course, the EXOS II with PMC8.

Hi Steve,

Yes, I would appreciate any testing you would like to do once we have completed our internal Alpha testing. We have yet to create a standard installation package for the new server/driver, but once we have done that, it will be easier to distribute and get feedback on it. I am hoping we can do this within the next couple of weeks (crossing my fingers!)

Re: Slewing behavior: POTH Hub vs Device Hub #ASCOM #iEXOS-100

Steve Lang
 

Hey Jerry.

1) I downloaded and installed devicehub (on Ascom Platofrm 6.4 sp1/latest/whatever) and noticed similar behavior with NINA. It worked for a while, then failed to slew and was generally not responsive. Had to restart ascom and use POTH instead, but I'm not convinced that devicehub is compatible with 6.4sp1 anyway. Will try to log a fault with dev's, but...

2) More importantly, I'm keen to test the new ascom driver with built in server (no POTH required.) Would prefer to do that with 6.4sp1 (my current setup) if that's useful to you, and I can test/run ascom conformance tool as well.

I would suggest that if you are having problems with specific applications on the new ASCOM 6.5 platform, that you report it to the Application developer and also to the ASCOM-Standards developers. There is an ASCOM Platform Groups.io forum where you can report these issues and discuss them at:

https://ascomtalk.groups.io/g/Help

I am not going to pursue this myself as we are currently actively working on our PMC-Eight ASCOM Server that we will be releasing soon.
This will do away with the need to use POTH or the Device Hub. In the meantime,

I suggest that anyone wanting to use the new ASCOM platform 6.5 that you select POTH when you download the platform in the list of components to download. This is not automatically selected since it has been deprecated in this new platform version, but it is still available to select and install.

Nice image.

I just bought a zenithstar 73 apo doublet and the exos 2 pmc eight mount, and a zwo asi294mc pro camera.  
My very first photo of the sky ever at age 61 lol.  So what went wrong?  Andromeda Galaxy
1.  too short of the exposures (30 seconds)
2.  I meant to capture images in the .Fitt format and chose .Ser by mistake
3.  It was going to be sun up soon so I rushed
4.  I did not have gain dialed in with the short exposure time
5.  Probably 10 other things I have not learned yet, lol

I did manage to polar align in sharpcap pro accurately, 3 star align with Explorestars, and slew to Andromeda with it in the corner of my FOV, so I guess I did something right for the first time ever trying this.

I am now addicted, learning today and installing/configuring astrotortilla plate solving tool to use in sharpcap pro.
fun fun fun

HI Pavel,

Yes, I responded to that discussion on CloudyNights. A 10 degree shift in angle with the north facing tripod leg is an effective strategy and will still result in a stable mount, but if you do that we always suggest that you provide some kind of anchor on the north leg in the ground to mitigate any chance of the mount toppling over. As long as the base of the tripod is level in the east/west direction it will work fine when tracking and aligning the mount. With an anchored north leg, you would probably be able to increase the altitude to an effective 80 degrees which should cover just about anyone wanting to use this mount.

Using iEXOS-100 beyond 60˚N/S #iEXOS-100

Pavel
 

Hi,
I would like to ask if there is someone using the iEXOS-100 mount beyond 60˚ north/south. It is obvious to anyone who tried that the R.A. lock knob and the latitude adjustment knob crash together somewhere after 59 degrees.  The question has just been raised on CloudyNights as well and some modifications have been suggested to avoid the crash, but apparently the mount still cannot be effectively set to more than 65 degrees.

As an occasional visitor to Northern Europe (one of the last areas without light pollution around, but with latitudes between 60 and 70 degrees), I have also thought about setting one leg of the tripod to the south and shortening it. It might be enough for visual observation. But would it be stable? And would it be usable for astrophotography? Any better ideas?

Best regards,
Pavel
