I had a chance to get out in the garden last evening, had a go at capturing NGC 7023 - Iris Nebula, only managed to get 12 good shots, 240sec x 12, combined in Photoshop with Mean Stacking. The dew was super heavy and currently I do not have any dew heaters (next purchase) so lost the battle after around 2 hours.
One interesting point is I captured these shots with the long exposure noise reduction switched on with the Sony A7Rii, so each shot took 8 mins to take and save, but as a result the noise levels were next to zero at 800 ISO, and at the end of the day the noise is always our enemy. I need to try a real pro level 'cooled' astro camera just to see how much better it could be, as the Sony A7Rii is just stellar !
I am very happy with the final shot, taken with my Skywatcher 100 ED Pro Esprit Scope on my NEQ6 mount, Skywatcher ED50 Guide Scope and Altair Astro ASI130mm camera, PHD2 of course. The sky was nice and clear with low light pollution, as around 5 miles from major town.
I do not take darks or flats or use Deep Sky Stacker, and I do not use filters, plus the camera has not been modified, so I am always delighted with the results I get from my set-up, as I have a deep level of respect for the hard work that most Astrophotographers go through to get the incredible images that we see here in Stargazers.
I have read that some people believe that the Sony Alpha cameras have a tendency to 'eat the stars' and not show everything captured, to be honest, I always used a Canon 60Da for many years for my astrophotography, until one day I though, what if my Sony A7Rii could be used, the first time I did this I released that it was time to sell the Canon 60Da, the 'Remote' (free) Sony software is almost as good as BackYardEOS, but the cameras are a decade apart in performance, the noise levels on the Sony are at least 4 maybe even 5 stops better than the Canon, that is the Sony A7Rii at 3200 iso equal to the Canon 60Da at 200 iso, so at 800 iso it is just so impressive. As you can see from the picture only 12 frames, stacked in Photoshop (Mean).
Open to comments and welcome a discussion/debate,
Hi guys and gals,
I recently purchased a pair of Nikon Aculon 10-22×50 Zoom binoculars for around $179 and I'm pretty disappointed with them. I live in Semi-rural northeast Texas and was looking for a good pair of binoculars for a casual stargazer like myself. I thought these would be the perfect pair, I was wrong. The field of view is pretty small and the focus is annoying. The view is like tunnel vision at 10× and too dark at 22×.
Do any of you individuals have any helpful suggestions on what exactly I should get that suites my individual needs?
I am looking for something that won't break the bank (under $300), has a large field of view, would allow me to see the moons of Jupiter, the Andromeda Galaxy, starclusters, nebulae, and maybe some of the Messier Objects? Also, without a tripod needed. I would like something that is comfortable on the eye and easy to hold.
Its asking a lot, I know. But I'm hoping some of you who are more knowledgeable on the subject would be able to help me out?
I'm considering buying a new telescope (my first telescope) for astrophotography, and some visual astronomy.
But I can't decide which type should I get. I mainly want to photograph deep sky objects. After testing some variations in Stellarium I am worried that some deep sky objects won't fit into the aperture of an 8" reflector.
I'm wondering which type should I get. And also I'm worried that I won't be able to photograph anything with a small refractor because I live near a city.
I am also open to any suggestions for a beginner astrophotography telescope. (around 800$ would be perfect)
I apologise if I made any writing mistakes.
Edit: I'm considering buying a Bresser Messier 203/800 or a William Optics Zenithstar 61 but I'm still open to any suggestions.

I'm currently using the Skywatcher Skyliner 200P reflector telescope with the 10mm and 25mm EPs that came with it. I have been viewing for a while now and think its time I upgraded the eyepieces. My budget is around £500. I'd like to be able to get a range of EPs that will provide me with wide view and higher magnification viewing (a shorter length, longer length and a barlow (or perhaps a powermate but I dont know much about these other than they are seemingly better than barlows - perhaps a little over budget)).
I enjoy both planetary and DSO viewing though if I had a preference it would be the latter. I wear eyeglasses having astigmatism in both eyes so eye relief is important. I mainly view from rural areas but will sometimes get it out in my rather light polluted back garden, so I am flexible with exit pupil size (the maximum being 31/35mm I reckon).
There is quite a selection of vendors and I am hoping you folks can help me narrow down my choices with some first hand experience
