Heres my first ever shot of the Orion Nebula in a Bortal 8 sky (as well as my first nebula). I stacked 52 light frames with Deep Sky Stacker (with dark, bias and flat frames) and then edited the stacked image with photoshop. The Core looks kind of blown out, so I'll need some shorter exposures to combine with this version.
I've also got a question linked to this: As i'm in a Bortal 8 location (on the edge of London, UK) i feel like i'm kind of limited by the exposure length befor the image just looks completly white/redisch from light pollution. For this photo i used 45 second Exposures but had to bump down the ISO to 200 to make it not look overexposed. In the end, does it really matter if the image looks overexposed due to light pollution because the light from the actuall DSO will still be there and can be filtered out through the power of editing or does this not really work?
*Any other comments or things i can/should change with the image would be greatly appreciated
Many Thanks to anyone taking their time to comment!
Hi All, I have a Star Adventurer but have had problems getting consistent results even when setup was as near to perfect as I can do, (this was focussed on due to this issue).
It took me a while to find out that when the eyepiece is is extended for focus it is very loose, so loose the graticule moves indipendantly of Polaris / background.
I have asked the supplier, "Astroshop.eu", to highlight the problem and ask for their feedback.
Question to Astroshop.eu:
I have had a constant issue with Polar Alignment. As I cannot use it so often, (visibility), it has taken me a while to identify the problem. When I adjust the polar scope focus the eyepiece is so loose that the graticule moves a lot laterally in all directions in the view. I can send a video but I think you can understand what I am saying.
Basically I must be getting something very wrong or there is an issue with the product. The thread is so loose it is entirely unstable.
Please advise what we can do about this.
Answer from Astroshop.eu:
1. "I'am sorry to say, but this is very normal and does not affect the function of the star adventurer".
2. "My collegue confirmed that this will not be a issue".
I have subsequently asked the guy to ask his colleague again, but some time has gone past and I have no further reply.
I think it is clear enough from the text and would really appreciate some experienced answer, any comments very welcome.
Additionally here are the videos I have sent to show them, (hand holding the phone so a bit shaky but issue can be seen. I'd really appreciate some help before I spend too much time again tring to get it to work, for reference the eyepiece wobble is around 3.5 graticule intervals, so not small. As it's full of grease it took me a long time to see how poor quality the Polarscope build quality is.
Thank you all, Andy
At last, I have 3D printed an adapter to attach an angled viewfinter to the polar telescope finder. This is for the Star Adventurer polar telescope, but I think it fit even others.
My document of how I did it:
It works so perfect compare to my film canister build adapter. This is my first real 3D printed product I will use so I have great times.
Not posted some images since my introduction in the welcome section. With the dark nights finally back here in Scotland I thought Id share some of the DSOs I managed to capture back in Feb-April just before the light nights rolled in at the start of May.
These were all stacked and edited in PixInsight.
1. The Running Man and Orion Nebula - less than an hour of integration time (SA pro + fuji 55-200mm lens).
2. Bodes and Cigar Galaxy - Less than an hour of integration time ( SA pro + SW 72 ED telescope).
3. Flame, Horsehead, Running Man and Orion Nebula - Less than an hour of integration time (SA pro + fuji 55-200mm lens).
4. Pinwheel Galaxy - 35 mins integration time (SA pro + SW 72 ED telescope).
5 Whirlpool Galaxy - 21 mins integration time (SA pro + SW 72 ED telescope).
6. Andromeda Galaxy - 1.5 minutes integration time (Move Shoot Move + fuji 55-200mm lens).
Hello everybody. My last imaging session left odd looking star trials in my photos, almost like a clockwise motion. My polar alignment and balance were good, so I am not sure why this issue is occuring. Below is an attached video of me scrolling through my subs. Any help/ advice would be greatly appreciated!
