Very well done. I'm sorry this has been a poor viewing season for you. The cold and clouds have made viewing impossible for me so it still will be 6 to 8 weeks for good viewing.
Be Well
Grey

Very many thanks, guys, for your appreciation.

Yes, last year was a very poor year for both viewing and imaging and so far, this year has proved no better.

Let's keep our fingers crossed and hope it improves !

Best regards,
Tel

Hi Tel,very well worth your patience i would say,a very nice result and nicely processed, sorry your imaging outing was cut short and only 5 subs captured, but a good result was had so you should be pleased with that.Nice to see that Atik314L in action again.

Despite me making everything ready in the obs on that same night,cloud thwarted me yet again.

Nice one Tel

regards,

Tom.

Howdy Tel,

That's a beauty of an M1! Can't wait until you are able to get the OIII and put them together in color. Although, I must admit, thanks to you and Tom, I'm liking the mono images better and better all the time.

Good luck friend!

Many thanks, Tom and Skip,

Yes, it would be nice and indeed be somewhat of a technological advance for me, if I can produce, align and colour an Ha/Olll composite according to the Hubble Palette, but I fear the weather Gods are once again conspiring against us !

It's all a little like one English comedian once observed and Mushroom Bill, (Andy), brought recently to my attention.

He, (the comedian), apparently bought a lottery ticket with a secret time recorded on it predicting, according to chance, the exact moment Birmingham City Football (soccer) Club would score its second goal.


On opening the ticket it proclaimed "October" !

Related to imaging, I know the feeling !

Opportunities are therefore still few and far between, but one positive aspect did emerge from my efforts.

Moving from an initial preview image of the Crab Nebula on my LT screen through a pure white light glass filter, I thought I might well have to refocus a tad when moving my filter wheel to the Ha filter position and thus incur significant delays necessitated by having to use a protracted exposure time to check.

Such however proved not to be the case: both the white light image and that provided by the Ha proved luckily to be parfocal !

I just hope that if I ever do get the opportunity to image in both Ha and Olll on the same night, the same applies !

Best regards,
Tel

One technical point I forgot to add.

I took no "Darks" or "Flats" to accompany the above image. I guess though, with the Atik 314L running, (at the time), at -23 Celsius, this camera is producing next to nothing in terms of "Noise". Thus, a great camera in its price range !

Best regards,
Tel

Hi Tel,

totally agree with you in regard to not taking darks with these Atik cameras as they are very low noise thanks to the cooling.In fact the fact sheet for these cameras does state that darks are unnessesary up to a given exposure time due to the cooling.

However, i do always take a few darks for one reason,possible hot pixels,i cannot speak of your Atik 314L, but both my old Atik 16ic mono, and my current Atik 314E mono, do sometimes suffer from the odd hot pixel or two, mainly in the summer months when nights are warmer and the cooling has to work harder to cool the sensor. So for that reason alone, i always take a few darks, winter and summer, just in case.

Another thing i do, is to leave the Atik powered up and running for about 30 minutes or so before attaching to the scope,this allows the time for desired cooling temps to be reached before imaging.

regards,

Tom.

Hi Tom,

All you say is quite true and I was probably lucky in this case not to have had to take any darks. This, I attribute to the fact that the ambient temperature was not much above freezing on the night, hence the cooling fan of the camera giving such a low figure.

Come the Summer, (that's of course the British Summer where only the rain gets warmer), and I may well experience one or two hot pixels as a result of lesser cooling.

And yes, I also allow the Atik to cool for a period of time until the camera's temperature shows a steady reading at the bottom of the "Nebulosity 2" progran page.

Best regards,
Tel

Thanks Tom. Though I have the Lasso tool, PSE does not have curves. However, I seem to get a grasp of what you state and not being able to find myself to come around processing is really bringing me down. As stated, I am working on a project which I hope will complete in a week or two.

Uggs, excellent and amazing M42.

Tel, excellent attempt and well processed given your location, hats off.

Thanks to everyone for the kind words about my M33 image.

Tel, the detail in that M1 is absolutely staggering!

Hi
Last night I had a rare excellent seeing session. I was imaging Jupiter and by chance caught Io just starting a transit.
I was using all Celestron gear , 8Se scope , CG-5 mount , neximage camera , even a Celestron 2 times barlow.
Look in the upper right to see Io. I will reprocess the video to even out the contrast later.

Link to my video of the orbital motion..

Superb detail on the video, Nomosnow !

I note you used a Neximage camera but was that the old version or the new(er) Neximage 5 ?

Best regards,
Tel

Hi Tel
The Neximage camera is the old original version camera. In regards to the detail on the video it was plain old luck as the seeing conditions were superb and that happens so rarely where I live.

Thanks, Nomosnow !

Weather/seeing conditions ?
In the main, weeks' long wall to wall cloud cover over here ! Hardly conducive of good imaging !

Oh hum !

Tel

Re: PSE, a;though there is no curves program with PSE, there is a plug-in that works well. Some info here:

Had one clear night a few days ago (a brisk 17F) so I squeezed in an M81.

Congratulations, Milby; looking good !

Plenty of dust lane detail there and the outer "arms" well captured !
