My name is Luiza, I am a student of Computer Engineering in São Paulo, Brazil and I would like to ask for your help.
As yesterday was the super pink moon day, I, at about 22:50, decided to take several photos of the moon using my phone and my non-digital telescope. And, analyzing the photos now, I realized that in some of them there are certain objects that I can't say exactly what they are. Could you help me identify them, please? I am not sure if they are satellites, ISS, Hubble, etc ... and I am very intrigued by themphotos.rar.
P.S: the objects are in the lower left corner of the images
Below are consecutive raw pictures if the ring nebula I took with my canon 600da and RCT 8" with neq6 pro guided with sharpcaps polar alignment procedure on the 15th of this month at 1am. I have 20 of these all 1600 iso auto wb 2 minute exposures. The problem will become apparent when you closely examine them, tracking is almost completely broken. I only stacked about 8 of them as most of the frames are unusable, some are star trails, some are commas and some are double exposures. This has become standard and getting worse since I tampered with my mounts gears and backlash adjustment. I have never been able to get consecutive 3min exposures on this mount, and I got it new 6 years ago, and only used it less than 30 times. I have spent roughly 20 hours trying to get rid of the backlash, coffee grinding noise and knocking when I press the directional keys to no avail, when the keys are pressed I notice the image wobbles violently. The go-to is also not working to 100% efficiently, I have to do guess work if I want my image centred.
Hi, I'm 100% new to astronomy, and I'm using a 7 year old eq2-mount telescope. After a few nights of awkwardly using the RA wheel I have to ask, aren't the RA slow motion controls on the opposite side to the eyepiece? How am I supposed to use them? Do I have to hug the telescope, or put the finder in the bottom? I also don't understand why one of the knobs' dial doesn't move when I move it around. Thank you very much, all help is appreciated. By the way there's a PDF by skywatchers I think, and that's all that came in the box as an instruction manual, the illustration is pretty accurate, my telescope is a reflective telescope
So it seems that after my clear out of the "Big" scopes life circumstances are meaning it is less and less likely that I will be able to do any astro which is a shame indeed.
I am therefore putting my little "Grab 'n' Go" setup up for sale
This is an absolute little beauty of a telescope. Really excells on planets and lunar work and solar (appropriate filters must be utilised - never point a telescope at the sun unless you are an experienced solar astro buff!)
I was very unimpressed with the flimsy tripod that came with the scope and managed to source a purpose built and absolutely solid portable pillar mount for it. Its is steel construct and is ingenious in that it allows levelling of the feet and also levelling at the plate too thanks to the utilisation of three springs and wing nuts to allow for easy adjustment.
Not only is the pillar great for the levelling option it has but it also has removable legs to allow for easy transportation to dark sky sites. The legs simply slid into place and the steel cable is tensioned by hand through easy use of the inline bolt brackets.
This is a whole package deal - perfect for anyone wanting to start astro or just have a great little portable setup.
SO, whats included? Included in this sale are the following:
- Skywatcher Skymax 127 Maksutov OTA - mint condition, no marks of blemishes
- Purpose built solid, tubular steel pillar levelling mount
- Baader Planetarium Hyperion 8-24mm clickstop Zoom Eyepiece
- Skywatcher 9x50 RACI Finderscope
- Greenwitch Astronomy original all weather telescope cover (you can't get these anymore!)
- Skywatcher Synscan Al-Az mount and Hand Control
- 12 V power cable
- Original factory fitted straight through 8x30 finder scope and bracket/shoe
- Instruction manual
This has all been kept in my observatory under the cover throughout. It really is in excellent condition and cost me quite a bit to put together so I have priced it competitively. Please no offers.
Is collection only and (of course) covid safe exchange. I prefer bank transfer as payment.
Hi guys, hoping you can help with the tracking problems I'm coming across with my astrophotography setup. I've been using it since August 2020 and have kind of put up with the problem until last night where I think it's getting worse...
Specs below (let me know if you need anything else):
William Optics Zenithstar 61 II (360mm F6.1) - Zenithstar 61Adjustable Field Flattener iOptron SkyGuider Pro Camera Mount Full Package K&F Concept Aluminium Tripod with 2kg weight Canon EOS 250d (cropped sensor 1.6x) The problem:
I take roughly 40 pics with each being 1 minute long at 1600 ISO and stack them on DeepSkyStacker. From a few people I know on the internet, it seems as though, with a very similar setup and same focal length, they can get around 3 mins of exposure with no problem. And that's without a guide camera.
With my 1 minute exposure, roughly 10 of 40 images are reasonable but the rest have star trailing or double stars (see attached downscaled, unedited pics of Orion nebula)
What I think it could be:
My first idea was the tripod, it's not the best but it's not cheap plastic, and it should be fine for a 1 min exposure. Then I thought it could be the iOptron tracker that could be faulty?
Every screw has been tightened, there's no play in any of the adapters/mounts.
I thought I'd post this here to see if anyone else has the same problem or has more experience/knowledge that could help. Also to see if there's an obvious problem before I spend hundreds on a new tripod or send the tracker back for a replacement.
Any help would be much appreciated!
