  1. Mine is flexible too but the t-shirt is lightweight enough it doesn't really move. Can you not run some wood down the inside to give it more support? Or invest in a carbon Fibre or I think you can also get proper remote operated closure fins I found this on the new filter system https://www.baader-planetarium.com/en/blog/rasa-8-extreme-images-michael-jaeger-with-ccd-camera-f2-highspeed-filter/ and its called the Baader FCCT (Filter changer camera tilter). I think this is the solution for the RASA 8" filter situation. I knew I had seen something more than just Facebook.
  2. Hi Tony, does the Varilock spacer fits between the filter drawer and the camera? I just leave the dew shield on and throw a t shirt over the end it can be left on for months which also saves me doing flats that frequently. The simple things
  3. I was looking into the RASA 8 as a portable setup in the field with my caravan. As far as I know this is a known problem with the UFC due to the small backfocus and looks like you've got a good solution, at least for mounting the filters but I suspect you will still have problems with collimating as you will need to remove the camera to access collimation screws? Removing the camera to collimate will mean you are back to square one most likely. I saw on Facebook in one of the many groups, that Baader are working on a solution for this due early 2020. From what I can gather is the new product will be a filter changer system with a built in tilt adjuster with adjustments on the side so it can be collimated without the need of removing the camera etc... This would be ideal for the RASA 8" It sounds like this may be the solution to deal with the 28mm backfocus of the RASA 8". I've got the 2inch Baader high speed filters already for my Hyperstar C11 but this never gets removed from the Observatory for the field, so this new changer could be ideal.
  4. Images taken with this scope using my DayStar Quark (also for sale)
  5. 11" Imperial ADM Losmandy type universal dovetail bars complete with some left over stickiness as shown in picture from standard use of duct tape (which I can clean off). Looking for £45. Payment by PayPal or Bank Transfer. Collection or delivery (delivery should not be more than a few £'s)
  6. ADM 100mm guide-scope rings and ADM type d series dovetail plate adapter. Could sell rings separate to patent adapters if required. Looking for £90. Payment by PayPal or Bank Transfer. Collection or postage (postage should be approx £9 for special delivery).
  7. Selling my DayStar Quark H-aplha eyepiece as I dont have time to use it. Comes with original box, power supply, manual etc.... Within 10 minutes of plugging in it's ready for solar observations or imaging with magnificent detail. I used this on my 152 (6") Starwave refractor for both breathtaking visual and high detail imaging. Sample photos posted are taken with this combination and an ASI 120MM camera. The 6" Starwave (also for sale) needed only a UV/IR filter fitted at the front of a diagnol with no recognisable distortion from thermals and no recognisable heating of the tube or optics. An excellent combination. Looking for £750. Payment by Paypal or Bank Transfer. Collection or I can post Special Delivery (should be around £9 for delivery).
  8. The Starwave 152mm delivers rich field views of the night sky using a large 6 inch / 152mm of unobstructed aperture at an incredible price. What's more, this lens isn't your average achromat lens. It is constructed from high quality Japanese Ohara and German Schott glass with top quality coatings, a very smooth polish and accurate surface figure free from striae. Another use for the Starwave 152mm Achromat is solar imaging. If you ever wanted to push your Daystar Quark or Quantum to the next level this optical tube has it all. 6" of aperture and a fast focal ratio for the fastest frame rates. If you're interested I also have a Daystar Quark for sale. Contact me for info. Scope has slight cosmetic mark as photographed where a small bit of its fancy sparkly coating has come off and also a minor scuff where the dew sheild knob has rubbed down side of tube upon retraction. These in no way hinder the scope performance. Solar images taken by me with this scope using my Daystar Quark Chromosphere (also for sale). Looking for £600 and payment by Paypal or Bank Transfer. Given the items size would prefer collection or meet up half way etc....
