Horeshead & Flame Nebulas
Jan 31, 2017 17:41:14 #
First I'll apologize for the haze from the light cloud cover I had to shoot thru.
I tried shooting 20 sec shots but was unable to recover any nebulosity thru the clouds.
At the 40 sec exposures I used the stars are blown out. I shot 20 Lights and use the
Dark, Bias and Flat masters I already had form night before. I got frustrated and packed
it in at 21:30. It is a perfect sky out today and I'm hoping it will hold thru the evening
where I will give this one another try. It's a work in progress learning this new
HyperStar setup at f/2.3 with a 2350mm Lens.

BUT, you got to play with the new toy! We have clouds rolling in, so hopefully I got some images to play with while it's cloudy.

Yes, you have to play to get used to the equipment.
Does anyone know of filters that are able to be used with Hyperstar? The camera attaches with a T2 thread (42mm x 0.75 pitch) and I don't see any filters available anywhere that are this size.

I rigged up a way to install filters on my RASA (I assume similar setup for the hyperstar) I only tried it once and appeared to get a bad reflection back to the image. I did purchase Celestron's LPR filter, it works very well.

Baader offers http://www.baader-planetarium.com/en/filters/universal-filter-changer/baader-ufc-s70-11%2214%22-rasa-adapter-telescope-sided.html
But I haven't heard anything about it, looks interesting, but may have same affect I had with my "rig". I've heard the fast f2.x requires special filters, maybe that's why I had issues when I tried a filter.

Those both look really cool.
All I want is to get in focus, and stay in focus. (And a RASA, and a CGE Pro, and a real camera, and a private Island, and a...)
One thing is adjusting your focus after each filter change...

There is no fun in being nicer.
So I'm working on perfecting what I have.
My Dad would have referred to it as trying to make a silk purse out of a sow's ear.
If you want something, you have to earn it. But I'm retired.
I was tired yesterday. And I'm retired today.

Thank you Brian, I'm sure when I can get to the mountain later this month I'll have much clearer images.

Hi Jim H I hope to have plenty of time to play with the settings next New Moon up on the mountain.
Not sure I'm going to mess around with any more filters. I have never had any success with them.
I do have an OIII filter I may work with on some images.

I agree Sonny it's time you move up to some more sophisticated equpement.
You have enough experience to warrant the move.

One of the issues with such a quick scope is the ability of using filters. From what I have read any scope faster than F4 requires certain filters to eliminate the spectrum shift that comes with such a quick scope. I suppose you could use a wider bandwidth, somewhere around 12-35nm but this would be at the cost of losing a large amount of contrast, which is the main draw to 3-5nm filters. I know Baader makes filters for F2 scopes, I am sure Astrodon and Custom Scientific probably makes a version also, but when Astrodon can charge almost a grand for one filter makes me rethink that avenue. Seeing the price of the filter drawers, holders and knowing I would want one drawer for each filter, not to mention the initial cost of the filters, would make me just break down and build a 3D printer and make my own.
Very nice images,
Matthew

Thanks for looking in Matthew I don't think I'm prepared to take on the $1000's in filter investments.
I'll just have to live with the methods I have at hand.

I don't think the Baader high speed F2 filters are too expensive, at least compared to the Astrodons.

It's a shame there's no way to put a 42mm filter inline with the C-8300 Camera.
