“Yet across the gulf of space, minds that are to our minds as ours are to those of the beasts that perish, intellects vast and cool and unsympathetic, regarded this earth with envious eyes, and slowly and surely drew their plans against us.” H.G. Wells, The War of the Worlds 😅👽

Messier 45 (M45), also known as the Pleiades or Seven Sisters, is a bright open star cluster located in the constellation Taurus, the Bull. The Pleiades cluster lies at an average distance of 444 light years from Earth. Messier 45 contains a number of hot, blue, extremely luminous B-type stars and is one of the nearest star clusters to Earth. It is the easiest object of its kind to see without binoculars. M45 has a core radius of 8 light years and its tidal radius extends to about 43 light years. The cluster is home to more than 1,000 confirmed members, but only a handful of these stars are visible to the naked eye. The total mass of M45 is estimated at about 800 solar masses. Imaged using a D7500 and SW 80ED Pro mounted on an AZ EQ6. I used the Optolong L-Pro filter as I image from a B6-7 location. 30 x 120 sec lights (no calibration frames) at ISO 400 (less aggressive!). 😀

Hey Paul, for the price, the Samyang 50mm is very good. The focus mech is spot on and as long as you stop it down to about f2.0 or 2.8 it will produce clear images without all the issues you'll encounter at f1.4. Having said that, I'm not sure there would be much between the Canon and Nikon?

Final image for this year of the Cygnus region of the Milky Way Galaxy. Taken using a Nikon D7500 and Samyang 50mm f1.4 lens (stopped down to f2.8) from Brecon Beacons National Park. The camera and lens were mounted on a Sky Watcher Star Adventurer Pro 2i allowing 15 x 120sec exposures at ISO 800.

The Galactic Core setting over the Brecon Beacon National Park (dark sky reserve). Imaged using a D7500 and Samyang 50mm f1.4 (stopped down to f2.8 to reduce star distortions at the edge of FoV). and Sky Watcher Star Adventurer Pro 2i. Sky shots consist of 20 x 2min tracked exposures at ISO 800 (no calibration frames), stacked in Sequator and processed in Ps.

Just installed the ZWO EAF to my the C9’25. Used the dedicated bracket for C8 - C9’25 SCTs. Easy business. However, it’s a busy enough image train at the business end! Looks like it’s more a case of the 533 than the D7500😅

It is Paul, The foreground shot of Pen y fan was taken during the ‘blue hour’ with the actually tracked shots of MW being a few degrees to the west and slightly higher. Both images were then merged using Ps Sky Replacement Tool. Had I attempted to capture the MW rise above the mountain range, the image would have suffered from LP from large towns to the rear of foreground.

Taken with a D7500 at ISO 800. 50mm f1.4 (stopped down to f2.8). Sky watcher Star Adventure Pro. 10 x 2min lights, no calibration frames

Thanks buddy and I really appreciate the image to show how it’s done. You’re are legend👍🍺🔭

Thank you. Although I’ve never used PIPP, can you explain what is meant by or how I save in old format? Lol. I downloaded the PIPP software but not really sure how to use. 😅

I captured several AVI in RAW 8 on Sharp Cap (all the same settings). For some reason Registax will only allow me to upload one of the five video files. When attempt to load the others I keep getting a message widow that says "FILE CANNOT BE LOADED" (see attached screen shot). Has anyone come across this? I have tried uninstalling and re-installing the software, including associated update but still the same problem.

I’ve a few! 😅

Thanks Marv, Lets get a strongly worded letter to the IAU! 👏😃👍

My goodness guys, that’s me told off🤣 To demonstrate my obedience; please find new images! 😅

Eastern Veil and Pacman nebulae, and M31!

Second go at M31

Had my Star Adventure Pro out at Brecon Beacons NP for a trial run. Managed to grab a few 120 sec tracked images of the Milky Way core (10 x 120 sec) rising over the southern entrance to Sennybridge Military Training Area. Also grabbed a set of 6 x 120sec exposers of the Cygnus Region. Both images were taken using my Nikon D7500 cropped sensor DSLR (ISO 800) and a Samyang 50mm lens stopped down to f2.8. The Milky Way image acquisition involved 6 x 60 sec static exposures of the foreground area (ISO 200) taken just prior to astronomical twilight. Then a 30min wait for total darkness prior to taking the tracked images of the Milky Way core that was rising over the Brecon Beacons in the background. I used the Ps Sky Replacement function in post processing to blend into a single composite image, which I think is a great tool. The image of Cygnus Region was a more straight foreword process of stacking and routine post processing in Ps. I really love the way you can see the Sadr Region Ha, including NGC 7000 and IC 1318. Overall, highly impressed with the Star Adventure Pro and given a bit more practice, I'll be ready for a few more nights in the field. Next time I'll take a few calibration frames to see if it improves the overall imagery. Milky Way sky.tif

Hi all, I recently purchase an Antares 6.3 SCT Focal Reducer and Celestron T-Adapter SC for use with my C9.25. My plan is to use both my Nikon D7500 and newly purchases ZWO ASI533 for imaging (camera use will be DSO dependent). I live in B7 class area and usually use my Opto-Long L-Pro or L-eXtreme filters, however, the 6.3 reducer and dedicated T-Adapter don't seem to allow the fitting of a 2" filter along the imaging train. Has anyone faced with a similar issue come up with a solution?

Yeh, I used a Dual Band but I’d need a lot more data to bring out the OIII on the crescent. If I get a clear night I’ll try and grab about 3hrs work and some calibration frames.

All in one night but without darks and an extremely hot DSLR sensor, hence the horrible noise! Couldn't believe it was 21 degrees when I started imaging!
