Modded 350D - Finally Firstlight :)

[Psychobilly]

At last I got a clearish night and have been able to Firstlight the Modded 350D on a Ha Target

Chose IC1396 as it was in the clearest patch of sky but towards the LP

Managed 7x300s before the skies were getting too light

Image needs far more data to smooth it out and flats etc...

(click to enlarge)

It was also my first chance to try the focusing masks for the 8" and the 66 they seemed to work quite well

Should have spent more time on IC1396 rather than faffing around on M45 for an hour or so - it was in the clearest patch of sky when I first setup and I was testing the focus masks on it...

Just great to be back out again for the first time in weeks...

Oh well better get off to work now

Billy...

That a cracker Billy Glad that the modded 350d is working well.

[Psychobilly]

Thanks John,

Needs a lot of work and a shed load more data... suppose it will be another month before I get another half decent night though Also struggling to get PixinsightLE to get a background out of it...

A CLS filter would help too, they do a cracking job on LP.

At last you get to try it - no chance here last night although the Moon did appear without a cloudy halo for a short period early in the evening!

Some more subs and you will be well away!

A CLS filter would help too, they do a cracking job on LP.

Thanks George

I use a 2" Hutech IDAS P2 on the nose piece of the William Optics Field Flattner III and a Lumicon Deep SKy SCT filter on the 8"

I find the Hutech is a superb filter getting rid of the LP with minimal color cast the Lumiucon is a bit stronger giving more of a color cast.

Hi Neil,

If its clear skies I need then I think I'll have to come and join you

Billy...

[Sam]

Nice image Billy! getting tempted to look at modding now....

[Psychobilly]

especially if you compare it to this...which was fromt he un-modded 350D...

Quite a difference

Tonight i'll be spending several hours on NGC7000 and IC 5070

Billy....

[Doc]

Billy your work always amazes me.

You are so dedicated to this.

And also where do you get all the clear skies from.....

[Psychobilly]

Thanks DOC

But last night was only my 3rd night in the obs since I built it... looks promising for tonight though - althought thats probably put the tin hat on it

Just taken 38 random clear sky images between 140 and 200 degrees offset from the sunset which I can hopefully get a set of flats from, another set of 20 bias frames and the cmaeras doing a set of darks at tonights settings as I type this...

So hopefully....

Must get my camera done soon nice one Billy few more subs and calibration and its a good un

Good luck tonight; nothing but cloud here... I'm not envious at all! :-) go go go! :-)

[Tim]

Wahey! There's no stopping you now! Just need some proper skies...

[saturn5]

Thanks for showing the difference between modded and unmodded Billy.

How much longer would you need an unmodded exposure to be to get the same as a modded image or is that not possible. :withstupid:

[Psychobilly]

The sensitivity to the Red wavelenghts has increased 5 fold whilst the red and blue has esentially stayed the same (a slight increase).

SO I suppose you would need 5 times the exposure to get the red about the same but would then be probably over exposing the blue and green .

Is that the right thinking?

looks like a good few hours tonight and the cam now has a PSU rather than batteries so tahts another limiting factor gone...

Can someone dim or better still switch the moon off please

Billy...

[saturn5]

Thanks for that Billy,so maybe for nebulae it would be just as well to take b&w images or is it possible to tweek enough red out of the image in photoshop without messing the rest of it up.

I'm just itching to get out and take that first long exposure image,probably be adventurous and do something unusual like M31

Come up here btw,the moons off Might clear later but this horrible really low level cloud is whizzing by,really damp stuff.

[glennbech]

The sensitivity to the Red wavelenghts has increased 5 fold whilst the red and blue has esentially stayed the same (a slight increase).

I have some light pollution from a nearby small city and have experienced to overexpose the red channel on a 3 minute exposure (even with a LP filter). With a non-modified camera the image would have been fine. (Well, not "fine" but properly exposed)...
