Well, I have captured Saturn for the first time and it’s a rush, but unfortunately, the universe conspired against me tonight.
The full moon was about 40 degrees away, it was hazy making stars look like they were boiling, and squadrons of mosquitoes attacked with Kamikaze like zeal!. I slapped myself silly but they eventually ran me out of my backyard, cursing all the way inside.
Hopefully next time seeing will be better and I’ll spray myself with repellent, and boy do i need to get my focus correct, i need a mask.
I knew from the start, that my Mak (which is new) was a bit out of collimation, I also knew that
alhough they hold collimation very well, they can be a pain to collimate.
With this in mind I scoured the net for articles and videos before attempting it rather than ending up
having a major wobbler when messing it up lol.
The key was to understand the push/pull system by which the spider is moved, and very small turns of the screws while adjusting them in sequence with each other.
I am happy to say that after 30 minutes, and thanks to Arcturus and a high power eyepiece, I have come
as close to perfect as I will get and I am more than happy with that. I took a cell phone shot, I wish it was as sharp and defined as the rings were visually but regardless, it was rewarding.
Both inside and outside focus was the same which is great, after snuggling up the locking screws, I won’t be messing with them anymore unless I drop it.
HEY its about time eh!!!! my first astrophoto with a dedicated cam using all the bells and whistles like iCap and Registax.
Programs that are still alien mumbo jumbo to me, but after eating a whole bunch of youtube videos and a bunch more trial and error, I finally pumped out this abomination, or so it must seem to you Pro's lol
I had a very vague idea of how to set up proper parameters in iCap for lunar imaging but I tried several settings and used youtube also, regarding wavelets, I basically dragged sliders all over the place
and watched changes occur. There is much to learn about post work in iCap, but i'll give it the old college try lol, my sole reason for posting is for feedback, this is where you Pro's shine, oh do I need
Anyway, it is my first astrophoto so no matter how much better it can be, well, it will do for now and I say that with a bit of swag because hey! at least I see craters there lol.
Exposure time.....no clue!
Number of frames....a whole bunch
Attempts.....way too many!
Wavelet values.....all over the place
De noising....didn't work at all I think
Resolution...12 something by ??? forgot
The conditions were horrid, a mak is not an imaging scope as I have learned the hard way, F1800 not good, I will definitely be looking at a much shorter FL scope,
Far too tight an image, I would need a 50 shot mosaic for full moon, or a focal reducer which I'm not sure anyone makes for my Mak.
Finally i have had some time tonight, under a clear sky, to point my new SW Mak 150 which i bought in December at the beautiful waxing crescent moon in the western sky outside my backyard porch.
i had no idea what to expect, having never even looked through a mak before, i set the scope out early and left it to equalize while i had dinner and some television, 3 hours later i realized i had put the scope out and bolted out lol.
I inserted my 24mm X cell LX reasoning that with the inherent narrow FOV of this scope i better use a 24 right off the bat, well it was just enough to squeeze the moon into the FOV entirely, and what a grand view it was, i really was blown away!.
First off i was struck by the beautiful contrast, the razor sharp limb against the inky black sky was fantastic, second was earthshine, beautiful looking and striking against the darker backdrop, craters speckled up and down the terminator with mare's and mountain ranges
beautifully contrasted and razor sharp.
Seeing conditions were very good, with minimal atmospheric distortion, i was able to push magnification up to 250 while maintaining image quality with minimal loss, i can honestly say that this Mak has provided me with a view of the moon i haven't seen since
looking through a Televue Frac at a star party years ago.
I can't wait to give Jupiter a go later tonight if the clouds don't roll in as expected since rain is in the forecast for the morning, but i don't mind anyway, i have waited since December for both weather and time to finally use my new scope, i can wait for jupiter.
Tonight, i felt as though i rediscovered the moon, such was the absolutely beautiful view through this scope which is new to me, i will be looking at some eyepieces with a bit longer FL to give me a bit more FOV around the moon, maybe a 30mm would do the trick.
Hello all! today i had a very brief moment outside with my 150 Mak before the clouds rolled in, between the time i put it out under clear skies and the two hours i gave it to equalize the clouds had rolled in but with some breaks here and there.
so during a short break in clouds i picked the brightest star and quickly checked collimation with my 14mm eyepiece, my question is if i should bother to adjust collimation because while im getting a beautifully symmetrical disc
with sharp rings on one end of focus, on the other end im getting a disc thats not so symmetrical with a bit of doppler effect going on where concentric rings are compressed a bit more on one end, dealt with this before on my big dob
but not sure to what degree it will affect performance in my mak. I remember some saying here that Mak's don't ever need collimation and hold collimation short of a hammer blow to the tube, should bother opening the pandora's box that
collimating can be in worst cases? (star was dead centre in FOV of course)
