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?
So, i have settled between 2 eyepieces for my scopes.
The explore scientific 6,5 mm 52degree
and the Skywatcher UWA Planetary 6mm
I have read that the explore scientific gives better contrast and views.
The explore scientific will give me 184x and barlowed 369x So should i trade less magnification for more detail?
I've realised that I'm not a fan of barlows, I'm also not loaded with cash. I love my two BST's 8mm and 25mm, I'm not so keen on my 15mm meade.
I've recently expanded my scope collection due to some inheritance with a 127 Mak, so my question is what would be a benefit to my eyepieces, replace the 15mm with a BST? Go lower than my 8mm? Go higher than 25mm? With BST's I would easily get two below £100 or go for something different and spend up to £100 on one eyepiece? Have a wide range of focal lengths and ratios over my three scopes, do I plan for different eyepieces per scope or stick to common eyepieces? Before anyone suggests Televues, I'll need to spend a fair bit on the wife before they turn up in the post? unless of course someone knows of deals going round

I had another go at imaging the shrinking Mars, this time without and with a x2 Barlow lens. The results are better with the Barlow, which is what one is led to expect. For whatever reason (probably bad seeing and/or low planets) when I tried a Barlow previously it just made the blur bigger. Equipment: C8 SE, ASI120MC, x2 Skywatcher kit Barlow element screwed directly into 1.25" barrel of the ZWO camera. This does seem to give x2 in practice. I did not use an ADC on the grounds that I shouldn't need one with Mars at an altitude of over 40 degrees.
3000 image video captured with Sharpcap. Processed in Registax6. I found that the Sharpcap exposure histogram did not appear to work on such a small image, so had to estimate the exposure. Yes, optical ADC correction would be better, but the dispersion seemed very small. Blowing up the image x2 in Registax showed a small colour fringe, which I took out with a single point of correction.
The images show some surface detail though the contrast is low (if you are using a flatscreen try viewing from below: ?) Mare Sirenum, with Mare Acidalium just discernible foreshortened at upper right.
