I'm trying to reignite my interest in astronomy after a few years off. I want to get into imaging (not in an expensive way) beginning with a simple setup. A few nights ago I was in my back garden with my Sky-Watcher Heritage-76 Mini Dobsonian and Canon EOS M camera connected to an eyepiece adapter (this one.. https://www.amazon.co.uk/Celestron-93640-Universal-Barlow-T-Adaptor/dp/B00009X3UV/ref=asc_df_B00009X3UV/?tag=googshopuk-21&linkCode=df0&hvadid=309904628344&hvpos=&hvnetw=g&hvrand=9227521492625195769&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9045736&hvtargid=pla-403917112227&psc=1&th=1&psc=1). I pointed my scope at the setting half moon and all I could see was a huge orange blob with a black circle in the middle, obviously this has something to do with focusing so what do I need to get this to work as my setup is already nearly bottom-heavy?
Either that or it might be a lot easier to use my Pixel 5 phone connected to the eyepiece, can anyone recommend a good adapter for this please? I've seen this on Amazon.. https://www.amazon.co.uk/Svbony-Universal-Cellphone-Binocular-Monocular-Black/dp/B016EILBAY/ref=sr_1_10?crid=2D2EEIA81TKYX&dchild=1&keywords=mobile+phone+telescope+adapter&qid=1606225704&sprefix=mobile+phone+tele%2Celectronics%2C175&sr=8-10, but folks say they've had mixed results.
Thanks very much.
What camera would you recommend to use with my Celestron SCT 9.25” ?
I would prefer a proper astrophotography camera rather than a DSLR.
I already have a focal reducer and would mostly want deep sky if possible (although my telescope may be too high mag for that), but would also enjoy planetary.
Any advice would be great guys.
Not posted some images since my introduction in the welcome section. With the dark nights finally back here in Scotland I thought Id share some of the DSOs I managed to capture back in Feb-April just before the light nights rolled in at the start of May.
These were all stacked and edited in PixInsight.
1. The Running Man and Orion Nebula - less than an hour of integration time (SA pro + fuji 55-200mm lens).
2. Bodes and Cigar Galaxy - Less than an hour of integration time ( SA pro + SW 72 ED telescope).
3. Flame, Horsehead, Running Man and Orion Nebula - Less than an hour of integration time (SA pro + fuji 55-200mm lens).
4. Pinwheel Galaxy - 35 mins integration time (SA pro + SW 72 ED telescope).
5 Whirlpool Galaxy - 21 mins integration time (SA pro + SW 72 ED telescope).
6. Andromeda Galaxy - 1.5 minutes integration time (Move Shoot Move + fuji 55-200mm lens).
I took a shot of M13 as a first test of my new orion 8 f/3.9. I have a couple of questions about the final result.
orion 8 f/3.9 mount skywatcher eq6r-pro canon 500d - astro-modded by me 40 exposures of 90 seconds and 40 darks 200 bias 200 flats capture software: nebulosity4 guide camera: zwo asi120mm guide scope: svbony 20 (80mm - 400mm) guide software: phd2 Processing:
siril preprocessing: align/callibrate/stack) siril post-processing: green nois reduction/ photometric noise reduction (very cool!)/deconvolution Result:
I attached a screenshot of siril (as the tif or jpg export did not show these "problems")
after preprocessing, I still have 2 problems (see the marked areas); what can be the cause of that? Are my flats not "correct"? The big mark, is a spot on the sensor, that is the "collateral damage" of me removing the Ir-cut filter. The other mark must be an other issue, I don't know so far the right part of the picture, shows some sort of glow; there was no moon during capturing; I live in a bortle class 5 area, but street lights are dimmed after midnight, till 05:00am and shots were taken around 01:00am. what can cause this glow Other remarks are very welcome - I hope to learn from it.
Thanks in advance,
This video is intended to be for someone who is thinking of buying their first scope but isn't sure which one is best. I would love it to be a good jumping off point for discussion and I hope some wise heads will wade in and answer questions and offer alternative opinions. Thx to astrostace and helena's astro and deddy dayag for contributing. I fear I'm going to have my head down making my next video as I'm currently astrobiscuiting full time (or at least till my loan runs out!). So all help much appreciated. 😉
