I’m completely new to Astrophotography and am just in the process of choosing my new rig.
does anyone living locally in Hertfordshire have any recommendations for the best areas with the least light pollution around Hemel Hempstead way?
I’m thinking Ashridge / Ivanhoe so it gets you high enough so leave the worse of light pollution behind - I tried taking some shots from my back garden and it was just consumed by yellow colour cast 😩
Any ideas I would grateful - found a thread on Hertfordshire skies but it favoured towards the east of Hertfordshire whereas I’m more West way.
I currently have a Canon T6 with a Opteka 500mm f8 lens ($87) that I use for lunar and solar photography. I recently purchased a full frame Canon EOS R and am thinking about getting a 800mm f11 Canon RF lens ($899). Will the quality on the new canon lens be significantly better than my Opteka lens? Is it worth the upgrade? Also, should I use my new full frame or my crop sensor (1.6 factor) to shoot? I want to get the best quality possible.
I am thinking about buying a Celestron Nexstar 6se to use for astrophotography at a very beginner level. I am thinking about using a ZWO ASI224MC as it seems a good option. I have a few questions about how to setup/use it - here they are:
1.) Do you just screw it on where the eyepiece is usually at?
2.) Do you just have the cable going to a computer where you have stacking spect where that stacks the photos it takes?
3.) Does it automatically take photos of planets and DSO’s?
4.) Does it need any filters to get color on nebulae as those are they primary things I want to photograph
Thats all, as you can see I am a beginner to astrophotography and just want to know how to use the camera to take decent pictures.
I think I need help with my Photoshop settings. I've been processing my photos and been very unhappy/depressed with the results. I then realized that they looked a lot better on my phone than on my PC screen. I did some testing and I discovered that Photoshop (CS4 - both 32bit and 64bit) and the basic Windows viewer [the two things I've been using all this time to look at my images] are displaying poorer quality views of my images than other viewers or programs. (see attached images) I think I just noticed this because I just got a CMOS OSC camera and was expecting a lot better than it seemed I was getting.
Do I have something set wrong in Photoshop? I really don't want to spend the money to get Pixinsight just right now (and the time to learn it) but I need to be able to see what the image really looks like while I'm processing it.
At first I thought the problem was with my monitor, but since I do see the correct image with some programs I've concluded that the issue must be with Photoshop itself. However, I have no idea at all how to fix it.
I've uploaded two views of an early processing stage of an Andromeda photograph.
This one shows the image as seen in Gimp, Irfan View, Windows Paint, on-line, the new Windows "Photos" or on other laptops, phones, etc.
This one shows the image as seen in Photoshop or in the Windows Photo Viewer or Photo Gallery on my PC. (I used screen capture to get this but it is accurate for what I see).
As you can see above, the image I'm seeing in Photoshop has problems. The main problem I notice is that the gradients of color do not flow smoothly but are concentric areas of flat color. No depth or subtlety.
Can this be fixed and if so what do I need to adjust in Photoshop or my PC? I'm using Photoshop CS4 and this effect shows up in both the 32bit and 64 bit versions.
Any help would be appreciated.
Thanks and Clear Skies Everyone
150mm F/5 Newt, as received new, view down eyecap collimator (no adjustments attempted by me):
I've read a couple of intro guides, so I'm led to believe that the off centre image of the secondary in the primary is normal for a fast reflector.
The whole image of the primary in the secondary seems to be reasonably central too.
My concern is obviously that the black dot from the collimation cap is not within the "doughnut" centre marking from the primary.
I've tried here to superimpose a circle with centre lines, but I'm not sure if I've got the circle itself correctly positioned (I'm not sure what I should be lining it up against):
Now, the interesting thing is that it's one of those jobbies with a sealed, non-collimatable primary. But I believe the secondary has all the usual degrees of movement.
Does it look likely to be far out?
I can try a star test tonight (first time for that too).
