M38, NGC1907 and Mr Smiley 21 Oct

[jgs001]

This is the stack of 25x60 seconds from last nights run on M38. I stopped after only 25 subs as the objective had dewed up again. Given that I cleared it before starting this run, and this was only 30 minutes later I decided enough was enough. It took all the gear an hour to dry out.

Anyway enough of that... Here's the image. I could be wrong and probably am, but is that a patch of red neb in the lower right, just under Mr Smiley's mouth ?

[jgs001]

Might that bit of neb be IC417 ?

Hi John

Nice M38 John, quite a horrible night for imaging with the high thin cloud........I do believe you have captured part of IC417 in your image as well, good job

Lovely framing JSG. IC147? Don't know that one - Liked the bubble stuff earlier btw - Think I'll have a crack myself.

[jgs001]

Cheers Dean. Nor did I, but I spotted the redness in this resulting image..

[LostNSpace]

Have a look at this image John

It shows M38 with IC417

Cheers Mark. Gonna have to go back and get a load more subs on this one.... Looks like there's a lot in there to be captured... Looks like I just missed M36 too... Maybe piggy back the camera and use a normal lens for a wider FOV... hmmmm.

[DeanWatson]

Ahhh! Pretty! Looks like an absolute female dog (sorry, this language checker is paranoiac... It picked me up for 'A clod of earth, usually covered in grass and rather damp and rhyming with Odd' the other day!) to get a decent exposure time on.

[jgs001]

Could be, bear in mind Dean that I'm tracking in AltAz so my exposure times are limited anyway. And this was only 25x60 seconds and I got some in there. I'm gonna go grab me 100 or so 60 second frames and see what comes out. (these timer remotes are wonderful things ).

[LostNSpace]

All depends what your FOV is John, you might just manage M36 as well, although getting more of IC417 in the image might be a different matter........

I have the same problem getting some targets in the FOV, if you look at my M31 from last night, M110 is missing, i would have to move M31 to the bottom of the image to capture M110 as well......

I think you are doing a fine job to get the length of subs you are doing just using Alt/Az, i know with my other mount im lucky to get 15secs.....

[DeanWatson]

AltAz? Remarkable! L'Audace, Toujours audace! (can't remember exactly what it means but it sounded appropriate- audaciousness or something...) Ah! timer remotes - best thing since sliced bread except you can't spread them with margarine (well, you can...)

[jgs001]

I'm using an ST80 clone scope. Not sure I could get M36 in and keep Mr Smiley intact... Maybe using the 55-250 lens, but then I won't have the CLS filter...

Thanks Mark. I'm able to get up to 120s subs, but I end up losing 50% of them to tracking errors in the drive train, so tend not to go that high. At 60s, I might lose between 5 and 10% to tracking errors, so I get a better hit rate and possible a longer total exposure.

Cheers Dean, Just figured it was worth a try and it's what I got and it's working well. The best news is I paid peanuts for the mount on ebay and got a 60mm frac thrown in (don't use that though). I don't want to know what you're spreading marg on timer remotes for

[MartinB]

Nice to see a bit of nebulosity creeping in. Another lovely cluster John

[Sam]

Great image John, You certainly captured a lot of different things in that area.

[Psychobilly]

Hi John,

I have said it before but I am going to say it again...

Your results with the 80 an the alt/az mount are amazing !!!

Billy....

[jgs001]

Thanks Martin. Cheers Sam. Thanks Billy. I'm of the firm belief that if I don't try I've got no hope. The worst that can happen with trying is that it doesn't work, push the gear and see what happens . This is another one I'm going to go back and grab a shedload more data.
