This is my first serious attempt at using my basic Sony A7 for AP on a WO-ZS71 mounted on the NEQ6.
Individual frames were captured using Sony's own software and that is where I ran into problems - it has a mind of its own!
Focusing using a Bahtinov Mask and Live View on the laptop seemed to work pretty well. The software then allowed me to take 9 x 10s and 4 x 30s exposures despite my best efforts to take 20 of each - it was not going to play ball.
These 13 images were stacked in DSS without any calibration frames (I took flats but I judged them not fit for purpose and I wasn't too impressed with my Darks either!). ABE was applied in PI along with MLT noise reduction. The image was cloned and the original incrementally stetched with HistogramTransofrmation and the clone with Arcsinh stretch. The two resulting images were then Mask Layered in Photoshop, levels applied and a small amount of additional noise reduction.
I think this A7 has some potential providing I can sort the Remote software and get myself some decent calibration frames.
All comments and suggestions greatfully received.
Thanks for looking.
heyyyyy its meeeee, kronosss and today there is a full moon(i missed out on the eclipse because of clouds... huh i guess i gotta wait another 19 years...)and i went out in the b ackyard with my 3" reflector telescope the celestron firstscope! The seeing was kinda bad... the full moon had less detail than the quarter.... anyway i figured i could see something else then i turned left and i saw orion(book-pun -intended) and the stars were quite faint(bad seeing full moon and light pollution.) i tried locating the orion nebula, after some time i stumbled across a small extremely faint smudge just barely distinguishable, then i turned and zoomed in,(75x) i saw 2 small kind of blurry spots of light (focusing wasnt great andi have the worst 4mm eyepiece in history...) with a very faint dark grey light around them keep in mind i saw that light when not looking directly at the nebula(read that it makes light appear brighter somewhere, it works lol) sooo is what i am seeing indeed it? or are my eyes playing tricks on me?
Took this last night in a rare beak in the clouds, still a work in progress and the moon was close. it was also a bit of an experiment on how my L pro max filter would help with moonlight, the answer is...quite well actually! the rest of the moon glare was mopped up in astro pixel processor.
55x60s, flats, darks and bad pixel map applied. stacked and processed in APP and final touch up in PS.
Still a work in progress and i'll add more data as and when i can
I thought I would share with you my first DSO taken with my new Orion 8" Ritchey Chretien F8 Telescope. The frame is made up of 12 x 4min shots, no light or dark frames, using my Sony A7Rii camera. The camera had the long exposure noise reduction switched on, which does help to reduce the total number of stars captured by the camera, as the Sony A7Rii does tend to overdo the number of stars captured. The telescope was mounted on my trusty skywatcher NEQ6 mount and the guiding was via PHD 'of course' via my skywatcher ED50 guide scope.
The shots were taken from my back garden in Stowmarket, Suffolk where I believe I am a Bortie 4 location, so the skies are mostly dark, with just a little light pollution from the main town, no filters used.
My normal telescope is a Skywatcher ED100 Pro Esprit F5.5, which is an incredibly sharp scope, but with a wide 550mm field of view, great for capturing the whole of Andromeda but a struggle with smaller images like the Iris Nebula. I will say the Orion RC scope did need to be collimated out of the box, which was a little disappointing, and it was not just a little out of collimation, it was a long way out, but with the use of a collimating tool, I soon had it dialled in.
First impressions of the Orion Ritchey Chretien 8" Telescope are fair, not super impressed, as it is nowhere near as sharp as my ED100 Esprit, but then this is to be expected based on price and telescope type, however, the pictures it has produced are pretty good, if you downscale the full 42MP from the Sony A7Rii camera, as can be seen in this picture.
I purchased this 8" Orion Ritchey Chretien OTA mainly for Planetary work, but as yet I have not had a chance to 'get onto' a planet, fingers crossed some clear nights will arrive soon, so I can try.
I welcome comments,
After being sick for what feels like an eternity, followed by two weeks of clouds and wind, i simply could not just let this night go as it was said to be yet another week or two with clouds on the way.
With my main scope not quite ready for use yet, i quickly hooked up the QHY5L-II-M to a canon 50mm lens, attached a 7nm Ha filter, and started looking for a decent target. I didn't need to look long before i saw Orion, and then it was set!
As the moon is currently 78% lit i must admit i was a bit worried, but i think the end result turned out OK, especially considering the relatively little data of just about 1 hour.
Exposure is 13x 300s (and 35x 30s for the core of M42) with the QHY5L-II at gain 12.
The lens is a Canon 50mm F/1.4@F/2.8
Darks applied to 300s exposures, but no flats or offset. Stacked in DSS, processed in PS and cropped to 16*9 size.
