Hi everyone

 

I'm keen to see pictures which have been taken with Celestron Evolution scopes.  Please post pics from your 6, 8 or 9.25 scopes. 

 

It will be really interesting to see what the Evolution scopes are capable of and also the types of cameras used. 

 

Thank you 

 

Kate

I'd been anticipating taking this set of shots all year, after seeing the event last winter.  I'm not really unhappy with this result, but with luck, I'll get to try again a few times this winter before the trees leaf out again.

The Evolution is primarily an observers scope, but here is my not very well done Dumbbell Nebula.  Canon 60D camera.  No processing- still figuring that out!

Hi Len,

 

Congratulations ! :waytogo:

 

Was the above a single frame ?

 

I've tried a little processing on it and I think it's turned out reasonably well if the above is true. If so, a few more frames, next time out, will indeed enhance your imaging in general.

 

There is a little star drift present but even that can often be removed, particularly if you keep the exposure times short which you will inevitably have to do so, operating as you are at the moment, from an Alt./Az. mount.

 

Keep 'em coming !

 

Best regards,

Tel

Nice!  Yeah mine was single frame, maybe 15 second exposure, probably iso 1600 or so.  There are good registax YouTube videos.  I'm going to try some of that.  I'll post if anything is at all acceptable.

Tel, lenrabinowitz, love those two shots.  Very impressive to see what a Schmidt Cassgrain can do where DSO are concerned.

It's not the sct so much as the alt az mount.  It's not really stable enough for dso's beyond after more then about a thirty second exposure.

I think you will be better off watching Deep Sky Stacker videos. RegiStax is more for planetary imaging.

Orion Nebula last night.  About a 15 second exposure.  Camera was attached to my Ultima Duo 21mm eyepiece with an lpr filter attached.  Getting there slowly but surely!

These pictures are amazing... and they say Schmidt Cassegrain can't do deep sky? I will be so delighted if I manage to achieve some of the shots posted here with my scope!  Thanks so much for posting them all.

Thank you Kate!  SCT scopes are really not suited for it, but the Evo will hold steady enough for about 30 seconds of exposure.  The things shown here are some of the "easier" dso's to shoot as they are relatively bright.  Go for it- have fun!  It's a challenge!

SCT's are not ideal for deep sky but with a focal reducer can be very effective.  Many folks here and on other forums have captured very respectable results more often with EQ mounts.

I think it's more the alt az mount.  The Evo is a nice mount but it will only track accurately for about thirty seconds.  I'm thinking I might get an eq mount for my Evo ota.  Anybody know if the VX mount would work with the Evo vixen rail?

Sorry for the quality but this a photo of the computer screen.
However as bad as this looks, in person it was great.
I used Astro-Video Systems MK IV Video Camera with the Vari-reducer set to .28 with the EVO 9.25.
This in my driveway in a red zone that is probably closer to white.
There is a fully lit school across the street and I was shooting over a street lamp.
I targeted the Horse Head Nebula as this has always been a big challenge from my driveway.
I used the latest beta from SharpCap at Matt's suggestion and I am really impressed with the results.
I set up the MK IV to only stack once internally with an integration of 254.

You have nothing to apologize for-  that is very difficult to get!  I think we Evo users are a little intimidated by some of the great amateur astrophotos we see.  Time for that to stop!  I am heartened by the fact that my photos don't seem to look too different from the other photos posted.  Keep at it troops!

Are you guys shooting through an eyepiece or any filters?  I have begun experimenting with that.

You guys are to be congratulated on turning out some good shots, (above).  :bow:  :bow:

 

Perhaps bear in mind though, that "shooting" is only a lesser part of the overall technique where, if the captured image has potential, processing will pay a very major roll in exploiting this.

 

In my view, I think the essentials are:

 

1) Whether you take your shots at prime or a-focus is irrelevant, but try to accumulate a reasonable number of frames for stacking. This will increase your signal to noise ratio and thus produce a smoother, "cleaner" image for processing.

 

2) If possible, use a software package rather depend purely on any DSLR camera to accumulate your selected number of frames or video. By its use, .you can see now much better the image appears on the "widescreen" before capturing it, (i.e. its brightness, contrast, colour, focus etc.) and thus be in a position to adjust easily, any one or more of these properties should it be necessary.

 

3)  Decide and concentrate upon getting a good image of one perhaps two objects only on any given night. Flitting from object is not to be recommended as I recall to my own cost !

 

4) Learn the basics associated with stacking and processing.

 

Registax is an ideal tool for stacking and processing lunar and planetary frames, while DSS, (Deep Sky Stacker), is great for DSOs. Both of these packages are free while to enhance the final, stacked image, Photoshop offer their excellent CS2 version as an equally free download.

 

Registax and DSS however, do not offer any DSO capture capability unlike Amcap, Sharpcap, Craterlet etc. do for planetary and lunar landscape frames. For this purpose, I personally use "Nebulosity" supplied by Stark Labs. but I gather there are other programs available depending on how much one wants to spend. Nebulosity costs, I believe, about $60 nowadays.

 

So, exampling Pugsx's lunar landscape above, which includes the crater Tycho, the attached gives some indication of what CS2 alone can do.

 

I hope it meets with your approval and that the above post may help you to increase your skills in astrophotography.

 

Best regards and keep 'em coming ! :waytogo:

All of these images are so cool. Keep 'em coming, I'm enjoying this. I just might have to give this a try with my point and shoot Canon. I've taken an image of the moon that way. Thanks everyone for sharing and clear skies.

Len, Yes, of course it will. That's one of real benefits of the both the SE and Evo mounts, they use the standard CG-5/Vixen compatible dovetail bars/saddles so they have the ability to swap the otas both on the mount and onto another mount like a gem.

 

 

Before going out and buying a nice little gem mount (a nice thing to have) I'd suggest a few things. You can do an awful lot in 15-45s in alt az mode on an Evolution or similar mount.

 

- get an SCT f6.3 reducer and an SCT-T adapter and a T-Ring for your camera. Remove the DSLR lens and the eyepiece/diagonal and go with the T thread connection from the reducer to the camera.

- get BYEOS (for Canon DSLR owners) and a stacking program (DeepSkyStacker for example) and learn to take a bunch of shorter exposures and then stack and process them. 

 

Yes this is just like planetary lunar imaging but on DSOs (you'll be using relatively short but not really short subs - usually in the 5-15 second range). With a little post processing work (brightness, contrast, histogram stretches, curves, etc.) you'll soon be creating nice images of many of the brighter DSOs.

 

Another fun direction is to get one of the newer cameras that were designed for guiding or solar system work (Mallincam Skyraider AG, Altair Astro GPCSM, ZWO 120 series, etc.) and a copy of the SharpCap software. Add an inexpensive .5x 1.25" focal reducer and you can start going after many DSOs and also view them live. SharpCap now includes live stacking features and these little inexpensive cameras (they are in the $200-250 range) do a surprisingly good job.

 

If you already have a DSLR both options cost you about the same amount (SCT reducer, adapters, software vs. small camera, reducer, free software).

 

Afocal imaging of DSOs (camera and lens connected to an eyepiece) is fun to try but it's not what you want to do in the longer term. I would definitely not spend any extra money on that type of setup (more expensive adapters and camera holders and such) ... that money would be better spent on either of the two other options.

Thanks for the feedback Mark!  I already have all of that stuff.  I think I am actually just going to try the new Evo Wedge.  Any thoughts on that, or wedges in general?

 

I am just barely a beginner in this.  Taken me eight months to get anything even remotely worth looking at.  Just now starting to think about processing.

 

Are you sure that the Evo OTA would fit on the VX?  If you look at the VX on Celestron's website, the bar looks to me a lot larger.

 

Also, I'm not sure you can get the VX mount without the tripod, or if the mount alone works with the Evo tripod.

 

All feedback appreciated.  Thanks!

 

Len
