One of the best cameras for Ha solar. With a 1/2" chip and large pixels, I used to fit the entire disc with lunt 35. I can still do a full disk with a quark using my TS 60ED and a reducer on the camera nose. This camera does not suffer from Newton's rings so saves a lot of time which is otherwise wasted in setting up a tilt adjuster.
Boxed with the cable, probably i have the disc as well, but not sure where in my astro dump it is. Software is available from the website though.
yesterday evening, I started observing the moon and sketching crater Copernicus even 15min before sunset. The contrast on the moon wasn't perfect yet, but on the other hand the contrast on the sketching paper was better - no need for LED. Copernicus with its prominent ray system is wonderfully appearing on the full moon but this time I just concentrated on the 96km crater itself:
Telescope: Celestron NexStar 127SLT
Eyepiece: ExploreScientific 6.7mm/82°
Date & TIme: June 12th, 2019 / 2130-2230 CEST
Location: home terrace, Dusseldorf region, Germany
Technique: Koh-i-Noor chalk and charcoal pens on black sketching paper
Size: appr. 30x30cm
Looking in my filed skeches, I figured out that I have visited Copernicus five years ago. Here's a comparison of the two sketches showing some changes in technique:
Hello everyone, I've got a question.
I want to upgrade the visual back on the Mak 127. The standard back on the Mak is not pleasant to work with as seen in the image. I need to get rid of this plastic thing. I purchased a mak to sct adapter when I bought the scope, I never got around to doing anything until now as I've just acquired a Baader 2.25x barlow as shown in the image.
Now, I've had a go of attaching the the Baader Barlow into the original plastic thing on the mak, it works .... but I'm not happy with the connection being made with the two locking screws, as there is still movement when the barlow, t-ring and Canon DSLR are all in the train.
I've been having a look on FLO for some work around, does anyone have some input as to whether this will work.
Mak to sct adapter-> Baader 2 inch to 1.25 reducer adapter->Baader 2.25x barlow + T ring & DSLR
Any input or a better way of securing everything is greatly appreciated!😊
Another option I've come across is this , Baader ClickLock 2"-1.25" Adapter and Baader T2 Extension Tube to bring it to 40mm when attached to the mak to sct adapter. Anyone have any experience with this?
since i started work on my observatory there hasn't been much time for AP, but since lunar photography is done in minutes i had a go yesterday.
SW AZGTI with the Skymax127 and Sony A6300 and Baader Neodymium Moon & skyglow filter.
100 frames taken and 50% used to stack in autostackerd.
lets imagine I wasn't to see a nice DSO about 15' size and I think it should look good nicely framed with a 1 deg field of view in the EP..
Which would give the better (or higher probability of seeing anything at all ) view from a semi urban light polluted home site (e.g Bortle 6)?
a) an 100mm f/6 refractor (fl 600mm) and a 10mm EP (60 deg afov, gain 60x = fov pf 1 deg)
(and exit pupil of 100mm / 60 = 1.6mm)
b) a 200mm SCT with focal reducer to give f/6 (fl 1200mm) and a 20mm EP (60 deg afov, gain 60x = fov of 1 deg)
(and exit pupil of 200 / 60 = 3.3mm)
My gut feeling is that the SCT should give a better view just based upon its 2xaperture - but Im not sure I understand fully the maths why.
Is the larger exit pupil going to result in a better / brighter / more successful view?
Or will the view be 'roughly' the same ?
Or have I got it all wrong.....
