Rosette TEC110FL

I had the little TEC110FL out over the Christmas break. I took several images.

This is the Rosette with a FLI ML8300 which is a good match to this optic with its small pixels.

HaLRGB 80 20 30 30 30.

PMX Mount, Lodestar guiding on a MMOAG. I used a Tak flattener as I also left the adapter at home for the TEC one. It was almost as good as the TEC one which is specific to this scope. Duh!

Nice image Greg. Smooth as, but I wonder if maybe it is just a bit to smooth. The stars look fine but the Neb looks soft.
How do you get clear skies? Beenvery ordinary here for months with only just a very few nights worth attempting an image but work has got in the way of those nights.

I am jealous.

Very nice! I like the saturation of the reds... very rich.

Lovely image Greg. Just fits in the field of view. How long were the subs?
Unfortunately I can relate to the "left stuff at home" experience.

Thanks Mark.

Yes the PMX is wonderful. Its very sophisticated.

Thanks Dougie. I see what you mean. There has been no smoothing or blur added in fact very little processing. Its one of the characteristics
of this scope that the colour comes out very easily. Its not very long exposure and I should really have done a lot more. Perhaps that gives the smooth look. It would never get the detail that Mike's 12 inch got or my CDK17 would get. But I like this little 110mm. Its the little scope that can.

Dark and clear skies abound at my dark site. All the cloud is east of the Great Dividing Range. Have a look at the satellite photos and you'll see the continent is often clear only the coastal areas cloudy.

Thanks Dave. Yes the red is rich. Its one of the things I like about this scope. It gives rich colours. Not sure if that is the coatings or the fluorite lens.

10 minutes is my standard although I often use 15 minutes for Ha or O111.

I also left counterweights at home so I used a PVC pipe as a spacer, a bit of colorbond as a washer and a couple of gym weights with tape as the weights! It all worked beautifully though.

Greg.

Yeh that's alright Greg, nice one, very traditional view

I notice three faint lines running across the fame at the bottom, they are of no consequence other than I wonder if you know what they are? I ask because during my Rosette imaging run I was getting a lot of similar lines through out the night appearing in many frames at similar angles. I just assumed they were satellite trails but they were all so similar and so often. Couldn't be column defects because thy were always at an angle to the axis of the CCD..? Are there just an inordinate number of satellites on that track given it is near the celestial equator..?

Median combine reduced them to almost invisible but I was concerned I had an issue with the camera at one stage...?

Mike

Nice image Greg.

I can see the lines too. Weird how they go exactly across the frame. Satellite trails should have some sort of angle to it. Which way are your columns Greg? Besides column defects start somewhere in the frame generally.

Must be satellites. My ML8300 camera is completely defect free. There aren't many luminance subs (2 I think) so they did not go away with median combine.

Thanks Louie. The red is very rich. I was happy with it consdering it is very low total exposure time and I was lucky to do any imaging with my jerry rigged setup.

The columns are vertical. I see a vertical line when the camera is warm. It disappears around 0 degrees C and by the time below zero there are zero defects. The chip is the cleanest chip I have ever seen.

Probably a lot of "traffic" around that area like M42.

Greg.

Yes, what Mike said - a nicely executed "traditional" rendition. Good one!

Cheers, Marcus

Thanks Marcus. Its not a 12 hour marathon but for the time spent I liked the result. I think a 10 - 12 hour version would go very deep as this little scope really lets the photons through.

Nice Rosette Greg. A little lacking in blue in my opinion but the detail is very good. I see those lines that people are talking about. Couldn't be a passing plane could it?

Cheers

Steve

Beautiful shot, Greg

How heavy is the PMX when you're carting it around and setting it up. Is it difficult to handle, weight wise??

Thanks Steve. It may well be a plane now yo mention it.

Weight would be listed on Bisque site but it feels like its about 25kgs. So medium heavy but manageable. Its a tad heavier than my Tak NJP mount I used to have. I wouldn't describe it as difficult to handle though.

Cheers Jen. Its one of the reasons I got this scope. The coatings/flourite seems to deliver richer colours.

Greg.
Probably be a littler easier to carry around than the MI1000GT
