Hi James,
 What is a half of a .965 bolt case. Also where do you find one?
Thanks
Doug doonan

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.

Comet Neowise near M53 #astrophotography

Mike Leemhuis
 

During yesterdays podcast, Jerry mentioned that Comet Neowise would be near M53 last night and asked people to supply pictures.  I'll attach my attempt from our Bortle 5 skies.   It was very cloudy but we did have about an hour when the clouds mostly parted and I was able to take pictures.  I ended up with 21 - 60 second exposures.  I processed the pictures in Deep Sky Stacker, using the mode to track the comet, then I used the mode to track the background stars.  I'll include both.  I also used Affinity Photo and Lightroom. The comet is obviously much dimmer compared to a few weeks ago and the tail has all but disappeared.  I am wondering though why it now appears to be reddish compared to the bright green color when it had a tail.  Any ideas?

Re: Explore Scientific EXOS-2 PMC-Eight GOTO Mount illuminated polar alignment + 90 degree polar alignment

Hi all,
The Mount Illuminated Polar Alignment scope in the EXOS2 has a reticule showing Polaris, NCP, and four other little circles that are supposed to be star positions. Does anybody know the names or catalogue numbers of the four stars that are supposed to be put into the little circles?

Thx Brian
Yes illuminated polar align scope solved, batteries dead boughtonly new a month ago so....
Getting a few tips on possible solutions, if they don't work, will take the plunge and get a guiding camera. Did not realise at start I would need such deep pockets.

Re: Explore Scientific EXOS-2 PMC-Eight GOTO Mount illuminated polar alignment + 90 degree polar alignment

Hi Nick, I'm on the UK south coast and am using the PS without any problems. The illumination issue is already covered by the other guys so I'll just advise you on the eyeballing problem;
The PS position obviously can be adjusted by loosening and tightening its bracket fixing to the mount. The reticle is turned by turning the PS in its bracket, not by turning the mount. Finally you will need to remove your viewing equipment, OTA, Camera from the mount before Polar aligning, otherwise eyeballing is a problem for sure. Once polar aligned you remount your equipment, turn the mount on and so on and your good to go....
I'm at 50degrees latitude here and place my mount on a table for convenient viewing height but the mount is only at half height for increased stability, that may help you,
kind regards, Brian

Hi Jerry.

Please see link.

Basically. As the dec mechanic housing is on the right hand side. I am having to use the guide scope in the finder scope position. But then it pulls left a bit more. I have played with the cbsking and its better but still wants to pull the opposite way.

Thanks

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!)

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. 

 

It is open source GNU code and so is entirely free to download and use.  Really saved my buns!

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.

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.
